Flutter AnimatedRotation Localization: Spinning Icons, Direction Indicators, and RTL-Aware Rotations

AnimatedRotation provides smooth rotation animations for widgets. Proper localization ensures that spinning icons, directional indicators, and loading animations work seamlessly across languages and handle RTL layouts correctly. This guide covers comprehensive strategies for localizing AnimatedRotation widgets in Flutter.

Understanding AnimatedRotation Localization

AnimatedRotation widgets require localization for:

• Directional indicators: Arrows and chevrons that flip in RTL layouts
• Loading spinners: Rotation direction and accessibility announcements
• Expandable sections: Rotation icons for collapsible content
• Refresh indicators: Pull-to-refresh rotation states
• Navigation arrows: Back/forward indicators respecting text direction
• Accessibility feedback: Screen reader announcements for rotation states

Basic AnimatedRotation with RTL Support

Start with a simple expandable section with RTL-aware rotation:

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

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

  @override
  State<LocalizedExpandableSection> createState() => _LocalizedExpandableSectionState();
}

class _LocalizedExpandableSectionState extends State<LocalizedExpandableSection> {
  bool _isExpanded = false;

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

    return Card(
      margin: const EdgeInsets.all(16),
      child: Column(
        children: [
          InkWell(
            onTap: () {
              setState(() => _isExpanded = !_isExpanded);
            },
            borderRadius: const BorderRadius.vertical(top: Radius.circular(12)),
            child: Semantics(
              button: true,
              expanded: _isExpanded,
              label: l10n.expandSectionAccessibility(
                _isExpanded ? l10n.expanded : l10n.collapsed,
              ),
              child: Padding(
                padding: const EdgeInsets.all(16),
                child: Row(
                  children: [
                    Expanded(
                      child: Text(
                        l10n.moreDetails,
                        style: Theme.of(context).textTheme.titleMedium,
                      ),
                    ),
                    AnimatedRotation(
                      turns: _isExpanded ? 0.5 : 0,
                      duration: const Duration(milliseconds: 300),
                      curve: Curves.easeInOut,
                      child: Icon(
                        Icons.keyboard_arrow_down,
                        color: Theme.of(context).colorScheme.primary,
                      ),
                    ),
                  ],
                ),
              ),
            ),
          ),
          AnimatedCrossFade(
            firstChild: const SizedBox.shrink(),
            secondChild: Padding(
              padding: const EdgeInsets.all(16),
              child: Text(l10n.detailsContent),
            ),
            crossFadeState: _isExpanded
                ? CrossFadeState.showSecond
                : CrossFadeState.showFirst,
            duration: const Duration(milliseconds: 300),
          ),
        ],
      ),
    );
  }
}

Accordion Menu with Rotating Icons

Refresh Button with Rotation Animation

Create a refresh button that rotates when pressed:

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

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

  @override
  State<LocalizedRefreshButton> createState() => _LocalizedRefreshButtonState();
}

class _LocalizedRefreshButtonState extends State<LocalizedRefreshButton> {
  double _rotationTurns = 0;
  bool _isRefreshing = false;
  DateTime _lastUpdated = DateTime.now();

  Future<void> _refresh() async {
    if (_isRefreshing) return;

    setState(() {
      _isRefreshing = true;
      _rotationTurns += 1;
    });

    await Future.delayed(const Duration(seconds: 2));

    if (mounted) {
      setState(() {
        _isRefreshing = false;
        _lastUpdated = DateTime.now();
      });
    }
  }

  @override

Settings Toggle with Animated Icon

Create settings toggles with rotating icons:

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

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

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

    return Scaffold(
      appBar: AppBar(title: Text(l10n.settingsTitle)),
      body: ListView(

          ),
          _SettingsTile(

            onChanged: (value) => setState(() => _autoRotate = value),
          ),
          _SettingsTile(
            icon: Icons.sync,
            title: l10n.syncTitle,
            subtitle: l10n.syncSubtitle,
            isEnabled: _syncEnabled,
            rotateIcon: true,
            onChanged: (value) => setState(() => _syncEnabled = value),
          ),
        ],
      ),

  }
}

class _SettingsTile extends StatelessWidget {
  final IconData icon;

  final ValueChanged<bool> onChanged;

  const _SettingsTile({

    required this.onChanged,
  });

  @override
  Widget build(BuildContext context) {
    return ListTile(
      leading: AnimatedRotation(
        turns: rotateIcon && isEnabled ? 0.5 : 0,
        duration: const Duration(milliseconds: 300),
        curve: Curves.easeInOut,
        child: AnimatedContainer(
          duration: const Duration(milliseconds: 300),
          padding: const EdgeInsets.all(8),
          decoration: BoxDecoration(
            color: isEnabled

            borderRadius: BorderRadius.circular(8),
          ),
          child: Icon(
            icon,
            color: isEnabled
                ? Theme.of(context).colorScheme.onPrimaryContainer
                : Theme.of(context).colorScheme.onSurfaceVariant,
          ),
        ),
      ),
      title: Text(title),
      subtitle: Text(subtitle),
      trailing: Switch(
        value: isEnabled,
        onChanged: onChanged,
      ),
    );
  }
}

Best Practices Summary

1. Handle RTL layouts: Flip rotation direction for directional indicators
2. Use appropriate turns values: 0.25 = 90°, 0.5 = 180°, 1.0 = 360°
3. Provide accessibility labels: Announce rotation state changes to screen readers
4. Combine with other animations: Mix rotation with opacity or scale for polish
5. Choose meaningful rotation directions: Up/down for expand/collapse, full rotation for refresh
6. Test with different locales: Verify directional animations work correctly in RTL
7. Use semantic rotation values: 0.125 (45°) for subtle effects, 0.5 (180°) for flip indicators
8. Consider animation duration: Shorter for interactive feedback, longer for loading states
9. Handle disabled states: Reduce opacity or change color when rotation is not active
10. Maintain consistency: Use the same rotation patterns throughout your app

Conclusion

AnimatedRotation is a versatile widget for creating smooth rotational animations in multilingual Flutter apps. By properly handling RTL layouts, providing meaningful accessibility announcements, and choosing appropriate rotation values, you create intuitive experiences for users worldwide. The patterns shown here—expandable sections, navigation arrows, loading spinners, and settings toggles—can be adapted for any application requiring animated rotational transitions.

Remember to test your rotation animations with various locales to ensure that directional indicators behave correctly regardless of the user's language preference.
