Flutter Switch Localization: Toggle States, Labels, and Accessibility

Switches are essential UI components for binary settings in Flutter apps. From enabling dark mode to toggling notifications, proper localization of switch labels, state descriptions, and accessibility announcements ensures users worldwide can understand and interact with your settings. This guide covers everything you need to know about localizing Switch widgets effectively.

Understanding Switch Localization Needs

Switches communicate state through:

  • Labels: What the setting controls
  • State descriptions: On/off, enabled/disabled
  • Accessibility announcements: Screen reader feedback
  • Semantic labels: Context for assistive technologies
  • Subtitle text: Additional explanation

Basic Switch with Localized Labels

Start with a properly localized switch using SwitchListTile:

import 'package:flutter/material.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart';

class LocalizedSwitchTile extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;

  const LocalizedSwitchTile({
    super.key,
    required this.value,
    required this.onChanged,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return SwitchListTile(
      title: Text(l10n.darkModeTitle),
      subtitle: Text(l10n.darkModeSubtitle),
      value: value,
      onChanged: onChanged,
      secondary: Icon(
        value ? Icons.dark_mode : Icons.light_mode,
        semanticLabel: value
            ? l10n.darkModeEnabled
            : l10n.darkModeDisabled,
      ),
    );
  }
}

ARB entries:

{
  "darkModeTitle": "Dark Mode",
  "@darkModeTitle": {
    "description": "Title for dark mode toggle switch"
  },
  "darkModeSubtitle": "Reduce eye strain in low light",
  "@darkModeSubtitle": {
    "description": "Subtitle explaining dark mode benefit"
  },
  "darkModeEnabled": "Dark mode enabled",
  "@darkModeEnabled": {
    "description": "Accessibility label when dark mode is on"
  },
  "darkModeDisabled": "Dark mode disabled",
  "@darkModeDisabled": {
    "description": "Accessibility label when dark mode is off"
  }
}

Settings Page with Multiple Switches

Create a complete settings page with properly localized switches:

class LocalizedSettingsPage extends StatefulWidget {
  const LocalizedSettingsPage({super.key});

  @override
  State<LocalizedSettingsPage> createState() => _LocalizedSettingsPageState();
}

class _LocalizedSettingsPageState extends State<LocalizedSettingsPage> {
  bool _darkMode = false;
  bool _notifications = true;
  bool _soundEffects = true;
  bool _autoUpdate = false;
  bool _analytics = true;
  bool _locationServices = false;

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return Scaffold(
      appBar: AppBar(
        title: Text(l10n.settingsTitle),
      ),
      body: ListView(
        children: [
          _buildSectionHeader(l10n.appearanceSection),
          SwitchListTile(
            title: Text(l10n.darkModeTitle),
            subtitle: Text(l10n.darkModeSubtitle),
            value: _darkMode,
            onChanged: (value) => setState(() => _darkMode = value),
            secondary: const Icon(Icons.palette),
          ),

          _buildSectionHeader(l10n.notificationsSection),
          SwitchListTile(
            title: Text(l10n.pushNotificationsTitle),
            subtitle: Text(l10n.pushNotificationsSubtitle),
            value: _notifications,
            onChanged: (value) => setState(() => _notifications = value),
            secondary: const Icon(Icons.notifications),
          ),
          SwitchListTile(
            title: Text(l10n.soundEffectsTitle),
            subtitle: Text(l10n.soundEffectsSubtitle),
            value: _soundEffects,
            onChanged: _notifications
                ? (value) => setState(() => _soundEffects = value)
                : null,
            secondary: const Icon(Icons.volume_up),
          ),

          _buildSectionHeader(l10n.privacySection),
          SwitchListTile(
            title: Text(l10n.analyticsTitle),
            subtitle: Text(l10n.analyticsSubtitle),
            value: _analytics,
            onChanged: (value) => setState(() => _analytics = value),
            secondary: const Icon(Icons.analytics),
          ),
          SwitchListTile(
            title: Text(l10n.locationServicesTitle),
            subtitle: Text(l10n.locationServicesSubtitle),
            value: _locationServices,
            onChanged: (value) => setState(() => _locationServices = value),
            secondary: const Icon(Icons.location_on),
          ),

          _buildSectionHeader(l10n.updatesSection),
          SwitchListTile(
            title: Text(l10n.autoUpdateTitle),
            subtitle: Text(l10n.autoUpdateSubtitle),
            value: _autoUpdate,
            onChanged: (value) => setState(() => _autoUpdate = value),
            secondary: const Icon(Icons.system_update),
          ),
        ],
      ),
    );
  }

  Widget _buildSectionHeader(String title) {
    return Padding(
      padding: const EdgeInsets.fromLTRB(16, 24, 16, 8),
      child: Text(
        title,
        style: TextStyle(
          fontSize: 14,
          fontWeight: FontWeight.bold,
          color: Theme.of(context).colorScheme.primary,
        ),
      ),
    );
  }
}

Accessible Switch with State Announcements

Create switches that properly announce state changes:

class AccessibleSwitch extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String title;
  final String subtitle;
  final IconData icon;

  const AccessibleSwitch({
    super.key,
    required this.value,
    required this.onChanged,
    required this.title,
    required this.subtitle,
    required this.icon,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return Semantics(
      toggled: value,
      label: title,
      hint: subtitle,
      onTap: () => onChanged(!value),
      child: MergeSemantics(
        child: SwitchListTile(
          title: Text(title),
          subtitle: Text(subtitle),
          value: value,
          onChanged: (newValue) {
            onChanged(newValue);
            _announceStateChange(context, title, newValue, l10n);
          },
          secondary: Icon(
            icon,
            semanticLabel: null, // Already in Semantics
          ),
        ),
      ),
    );
  }

  void _announceStateChange(
    BuildContext context,
    String settingName,
    bool newValue,
    AppLocalizations l10n,
  ) {
    final message = newValue
        ? l10n.switchTurnedOn(settingName)
        : l10n.switchTurnedOff(settingName);

    SemanticsService.announce(message, TextDirection.ltr);
  }
}

ARB entries for announcements:

{
  "switchTurnedOn": "{setting} turned on",
  "@switchTurnedOn": {
    "description": "Screen reader announcement when switch is turned on",
    "placeholders": {
      "setting": {
        "type": "String",
        "example": "Dark mode"
      }
    }
  },
  "switchTurnedOff": "{setting} turned off",
  "@switchTurnedOff": {
    "description": "Screen reader announcement when switch is turned off",
    "placeholders": {
      "setting": {
        "type": "String",
        "example": "Dark mode"
      }
    }
  }
}

Adaptive Switch for Platform Conventions

Different platforms have different switch conventions:

class AdaptiveLocalizedSwitch extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String title;
  final String? subtitle;

  const AdaptiveLocalizedSwitch({
    super.key,
    required this.value,
    required this.onChanged,
    required this.title,
    this.subtitle,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return SwitchListTile.adaptive(
      title: Text(title),
      subtitle: subtitle != null ? Text(subtitle!) : null,
      value: value,
      onChanged: onChanged,
      // iOS-style uses "on/off" semantics
      // Android uses "checked/unchecked"
      controlAffinity: ListTileControlAffinity.trailing,
    );
  }
}

// Platform-specific state text
class PlatformAwareSwitchTile extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String title;

  const PlatformAwareSwitchTile({
    super.key,
    required this.value,
    required this.onChanged,
    required this.title,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;
    final platform = Theme.of(context).platform;

    String stateText;
    if (platform == TargetPlatform.iOS ||
        platform == TargetPlatform.macOS) {
      stateText = value ? l10n.switchStateOn : l10n.switchStateOff;
    } else {
      stateText = value ? l10n.switchStateEnabled : l10n.switchStateDisabled;
    }

    return ListTile(
      title: Text(title),
      subtitle: Text(stateText),
      trailing: Switch.adaptive(
        value: value,
        onChanged: onChanged,
      ),
    );
  }
}

ARB entries:

{
  "switchStateOn": "On",
  "@switchStateOn": {
    "description": "iOS-style 'On' state text"

  },
  "switchStateDisabled": "Disabled",
  "@switchStateDisabled": {
    "description": "Android-style 'Disabled' state text"
  }
}

Feature Toggle with Confirmation Dialog

Some switches need confirmation before toggling:

class ConfirmableSwitchTile extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String title;
  final String subtitle;
  final bool requiresConfirmation;

  const ConfirmableSwitchTile({
    super.key,
    required this.value,
    required this.onChanged,
    required this.title,
    required this.subtitle,
    this.requiresConfirmation = false,
  });

  @override
  Widget build(BuildContext context) {
    return SwitchListTile(
      title: Text(title),
      subtitle: Text(subtitle),
      value: value,
      onChanged: (newValue) async {
        if (requiresConfirmation && !newValue) {
          final confirmed = await _showConfirmationDialog(context);
          if (confirmed == true) {
            onChanged(newValue);
          }
        } else {
          onChanged(newValue);
        }
      },
    );
  }

  Future<bool?> _showConfirmationDialog(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return showDialog<bool>(
      context: context,
      builder: (context) => AlertDialog(
        title: Text(l10n.confirmDisableTitle),
        content: Text(l10n.confirmDisableMessage(title)),
        actions: [
          TextButton(
            onPressed: () => Navigator.pop(context, false),
            child: Text(l10n.cancelButton),
          ),
          TextButton(
            onPressed: () => Navigator.pop(context, true),
            style: TextButton.styleFrom(
              foregroundColor: Theme.of(context).colorScheme.error,
            ),
            child: Text(l10n.disableButton),
          ),
        ],
      ),
    );
  }
}

ARB entries:

  "confirmDisableTitle": "Confirm Action",
  "@confirmDisableTitle": {
    "description": "Title for confirmation dialog"
  },
  "confirmDisableMessage": "Are you sure you want to disable {feature}?",

  "@cancelButton": {
    "description": "Cancel button text"
  },
  "disableButton": "Disable",
  "@disableButton": {
    "description": "Disable action button text"
  }
}

Switch with Loading State

Handle async operations with loading indicators:

class AsyncSwitchTile extends StatefulWidget {
  final bool initialValue;
  final Future<bool> Function(bool) onToggle;
  final String title;
  final String subtitle;

  const AsyncSwitchTile({
    super.key,
    required this.initialValue,
    required this.onToggle,
    required this.title,
    required this.subtitle,
  });

  @override
  State<AsyncSwitchTile> createState() => _AsyncSwitchTileState();
}

class _AsyncSwitchTileState extends State<AsyncSwitchTile> {
  late bool _value;
  bool _isLoading = false;
  String? _errorMessage;

  @override
  void initState() {
    super.initState();
    _value = widget.initialValue;
  }

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return SwitchListTile(
      title: Text(widget.title),
      subtitle: _errorMessage != null
          ? Text(
              _errorMessage!,
              style: TextStyle(
                color: Theme.of(context).colorScheme.error,
              ),
            )
          : Text(widget.subtitle),
      value: _value,
      onChanged: _isLoading ? null : _handleToggle,
      secondary: _isLoading
          ? const SizedBox(
              width: 24,
              height: 24,
              child: CircularProgressIndicator(strokeWidth: 2),
            )
          : null,
    );
  }

  Future<void> _handleToggle(bool newValue) async {
    final l10n = AppLocalizations.of(context)!;

    setState(() {
      _isLoading = true;
      _errorMessage = null;
    });

    try {
      final success = await widget.onToggle(newValue);
      if (success && mounted) {
        setState(() {
          _value = newValue;
          _isLoading = false;
        });
      } else if (mounted) {
        setState(() {
          _isLoading = false;
          _errorMessage = l10n.switchUpdateFailed;
        });
      }
    } catch (e) {
      if (mounted) {
        setState(() {
          _isLoading = false;
          _errorMessage = l10n.switchUpdateError;
        });
      }
    }
  }
}

ARB entries:

{
  "switchUpdateFailed": "Failed to update setting. Please try again.",
  "@switchUpdateFailed": {
    "description": "Error message when switch toggle fails"
  },
  "switchUpdateError": "An error occurred. Please check your connection.",
  "@switchUpdateError": {
    "description": "Error message when switch toggle throws exception"
  }
}

Custom Styled Switch with Labels

Create a switch with visible on/off labels:

class LabeledSwitch extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;

  const LabeledSwitch({
    super.key,
    required this.value,
    required this.onChanged,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return Row(
      mainAxisSize: MainAxisSize.min,
      children: [
        Text(
          l10n.switchLabelOff,
          style: TextStyle(
            color: value
                ? Theme.of(context).disabledColor
                : Theme.of(context).colorScheme.onSurface,
            fontWeight: value ? FontWeight.normal : FontWeight.bold,
          ),
        ),
        Padding(
          padding: const EdgeInsets.symmetric(horizontal: 8),
          child: Switch(
            value: value,
            onChanged: onChanged,
          ),
        ),
        Text(
          l10n.switchLabelOn,
          style: TextStyle(
            color: value
                ? Theme.of(context).colorScheme.primary
                : Theme.of(context).disabledColor,
            fontWeight: value ? FontWeight.bold : FontWeight.normal,
          ),
        ),
      ],
    );
  }
}

ARB entries:

{
  "switchLabelOn": "ON",
  "@switchLabelOn": {
    "description": "Label text showing switch is on"
  },
  "switchLabelOff": "OFF",
  "@switchLabelOff": {
    "description": "Label text showing switch is off"
  }
}

RTL Support for Switches

Handle right-to-left layouts properly:

class RTLAwareSwitchTile extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String title;
  final String subtitle;
  final IconData icon;

  const RTLAwareSwitchTile({
    super.key,
    required this.value,
    required this.onChanged,
    required this.title,
    required this.subtitle,
    required this.icon,
  });

  @override
  Widget build(BuildContext context) {
    final isRTL = Directionality.of(context) == TextDirection.rtl;

    return SwitchListTile(
      title: Text(title),
      subtitle: Text(subtitle),
      value: value,
      onChanged: onChanged,
      secondary: Icon(icon),
      // On RTL, switch goes to left, icon to right
      controlAffinity: isRTL
          ? ListTileControlAffinity.leading
          : ListTileControlAffinity.trailing,
    );
  }
}

// Custom RTL-aware switch row
class CustomRTLSwitch extends StatelessWidget {
  final bool value;
  final ValueChanged<bool> onChanged;
  final String label;

  const CustomRTLSwitch({
    super.key,
    required this.value,
    required this.onChanged,
    required this.label,
  });

  @override
  Widget build(BuildContext context) {
    return Directionality(
      textDirection: Directionality.of(context),
      child: Row(
        children: [
          Expanded(
            child: Text(
              label,
              style: Theme.of(context).textTheme.bodyLarge,
            ),
          ),
          Switch(
            value: value,
            onChanged: onChanged,
          ),
        ],
      ),
    );
  }
}

Switch Group with Mutual Exclusivity

Some settings are mutually exclusive:

class ExclusiveSwitchGroup extends StatelessWidget {
  final Map<String, bool> options;
  final ValueChanged<String> onSelect;

  const ExclusiveSwitchGroup({
    super.key,
    required this.options,
    required this.onSelect,
  });

  @override
  Widget build(BuildContext context) {
    final l10n = AppLocalizations.of(context)!;

    return Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: [
        Padding(
          padding: const EdgeInsets.all(16),
          child: Text(
            l10n.selectOneOption,
            style: Theme.of(context).textTheme.titleMedium,
          ),
        ),

Testing Localized Switches

Write comprehensive tests:

import 'package:flutter_test/flutter_test.dart';

void main() {
  group('Localized Switch Tests', () {
    testWidgets('displays localized title and subtitle', (tester) async {
      await tester.pumpWidget(
        MaterialApp(
          localizationsDelegates: AppLocalizations.localizationsDelegates,
          supportedLocales: AppLocalizations.supportedLocales,
          locale: const Locale('en'),
          home: Scaffold(
            body: LocalizedSwitchTile(
              value: false,
              onChanged: (_) {},
            ),
          ),
        ),
      );

      expect(find.text('Dark Mode'), findsOneWidget);
      expect(find.text('Reduce eye strain in low light'), findsOneWidget);
    });

    testWidgets('announces state change for accessibility', (tester) async {
      final announcements = <String>[];

      tester.binding.defaultBinaryMessenger.setMockMethodCallHandler(
        SystemChannels.accessibility,
        (message) {
          final data = message.arguments as Map;
          announcements.add(data['message'] as String);
          return Future.value();
        },
      );

      await tester.pumpWidget(
        MaterialApp(
          localizationsDelegates: AppLocalizations.localizationsDelegates,
          supportedLocales: AppLocalizations.supportedLocales,
          home: Scaffold(
            body: AccessibleSwitch(
              value: false,
              onChanged: (_) {},
              title: 'Test Setting',
              subtitle: 'Test description',
              icon: Icons.settings,
            ),
          ),
        ),
      );

      await tester.tap(find.byType(Switch));
      await tester.pump();

      expect(announcements, contains('Test Setting turned on'));
    });

    testWidgets('shows confirmation dialog when required', (tester) async {
      await tester.pumpWidget(
        MaterialApp(
          localizationsDelegates: AppLocalizations.localizationsDelegates,
          supportedLocales: AppLocalizations.supportedLocales,
          home: Scaffold(
            body: ConfirmableSwitchTile(
              value: true,
              onChanged: (_) {},
              title: 'Notifications',
              subtitle: 'Receive alerts',
              requiresConfirmation: true,
            ),
          ),
        ),
      );

      await tester.tap(find.byType(Switch));
      await tester.pumpAndSettle();

      expect(find.text('Confirm Action'), findsOneWidget);
      expect(find.text('Cancel'), findsOneWidget);
      expect(find.text('Disable'), findsOneWidget);
    });

    testWidgets('handles RTL layout correctly', (tester) async {
      await tester.pumpWidget(
        MaterialApp(
          localizationsDelegates: AppLocalizations.localizationsDelegates,
          supportedLocales: AppLocalizations.supportedLocales,
          locale: const Locale('ar'),
          home: const Directionality(
            textDirection: TextDirection.rtl,
            child: Scaffold(
              body: RTLAwareSwitchTile(
                value: true,
                onChanged: null,
                title: 'الوضع الداكن',
                subtitle: 'تقليل إجهاد العين',
                icon: Icons.dark_mode,
              ),
            ),
          ),
        ),
      );

      // Verify switch is on the correct side for RTL
      final switchFinder = find.byType(Switch);
      final switchWidget = tester.getRect(switchFinder);
      final screenWidth = tester.binding.window.physicalSize.width;

      // In RTL, switch should be on the left side
      expect(switchWidget.left, lessThan(screenWidth / 2));
    });
  });
}

Best Practices Summary

  1. Always provide context: Use subtitles to explain what the switch does
  2. State announcements: Announce changes for screen reader users
  3. Platform conventions: Use adaptive switches for native feel
  4. Confirmation dialogs: Require confirmation for destructive toggles
  5. Loading states: Show progress for async operations
  6. RTL support: Ensure proper layout in RTL languages
  7. Semantic labels: Provide meaningful accessibility labels
  8. Error handling: Display clear error messages when toggle fails

Conclusion

Properly localized switches are crucial for a good user experience in multilingual Flutter apps. By following these patterns, you ensure that all users can understand and interact with your settings regardless of their language or accessibility needs.

Key takeaways:

  • Use SwitchListTile for consistent Material Design
  • Provide both title and subtitle translations
  • Implement proper accessibility announcements
  • Handle RTL layouts appropriately
  • Test with multiple locales and screen readers
