A comprehensive Flutter plugin for managing dynamic app shortcuts on both iOS and Android platforms. This package provides a unified API to create, manage, and handle app shortcuts with support for both cold starts (app launched from shortcut) and hot starts (shortcut activated while app is running).

Features

• 📱 Cross-Platform Support: Works seamlessly on both iOS and Android
• 🔄 Stream-Based Events: Handle shortcut actions through a convenient stream interface
• ❄️ Cold Start Support: Properly handles app launches from shortcuts
• 🔥 Hot Start Support: Handles shortcut activations while app is running
• 🎯 Dynamic Shortcuts: Create and manage shortcuts programmatically
• 🖼️ Custom Icons from Flutter Assets: Use icons from your Flutter assets for both platforms
• 📋 Subtitles: Optional subtitles for shortcuts (iOS only)

Demo

Android

iOS

Installation

Add to your pubspec.yaml:

dependencies:
  launcher_shortcuts: ^latest_version

Also, add your shortcut icons to the assets section in pubspec.yaml:

flutter:
  assets:
    - assets/launcher/  # directory containing your shortcut icons

Platform-Specific Setup

Android

• Min SDK version is 25
• In your AndroidManifest.xml, add the following within the <application> tag:

<activity android:launchMode="singleInstance"></activity>

The key attribute is android:launchMode="singleInstance" which prevents app duplication when using shortcuts.

iOS

• Min iOS version is 12.0
• No additional setup is required for iOS. The plugin automatically handles everything through the AppDelegate.

Basic Usage

1. Initialize the plugin

Ensure to use initialize after WidgetsFlutterBinding.ensureInitialized() in your main.dart:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await LauncherShortcuts.initialize();
  runApp(MyApp());
}

2. Set up shortcut handling

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

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

  @override
  void initState() {
    super.initState();

    // Listen for shortcut events
    LauncherShortcuts.shortcutStream.listen(_handleShortcut);
  }

  void _handleShortcut(String type) {
    // Navigate based on shortcut type
    if (navigatorKey.currentState != null) {
      navigatorKey.currentState?.pushNamed(type);
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: navigatorKey,
      // ... rest of your app configuration
    );
  }
}

3. Create and register shortcuts

Future<void> _registerShortcuts() async {
  try {
    await LauncherShortcuts.setShortcuts([
      ShortcutItem(
        type: '/search',
        localizedTitle: 'Search',
        androidConfig: AndroidConfig(icon: 'assets/launcher/search.png'),
        iosConfig: IosConfig(
          icon: 'search',
          localizedSubtitle: 'Find items quickly',
        ),
      ),
      ShortcutItem(
        type: '/settings',
        localizedTitle: 'Settings',
        androidConfig: AndroidConfig(icon: 'assets/launcher/settings.png'),
        iosConfig: IosConfig(
          icon: 'settings',
          localizedSubtitle: 'App configuration',
        ),
      ),
    ]);
  } catch (e) {
    print('Error setting shortcuts: $e');
  }
}

4. Clear shortcuts when needed

Future<void> _clearShortcuts() async {
  try {
    await LauncherShortcuts.clearShortcuts();
  } catch (e) {
    print('Error clearing shortcuts: $e');
  }
}

Advanced Usage

Handling cold starts

The plugin automatically handles cold starts (when the app is launched from a shortcut). The shortcut action will be delivered through the same stream as hot start actions.

Custom navigation handling

void _handleShortcut(String type) {
  if (navigatorKey.currentState != null) {
    // For cold starts, replace the initial route
    if (navigatorKey.currentState!.canPop()) {
      navigatorKey.currentState?.pushReplacementNamed(type);
    } else {
      navigatorKey.currentState?.pushNamed(type);
    }
  }
}

Validating shortcut actions

// Define valid routes in your app
final List<String> _validRoutes = ['/search', '/settings', '/profile'];

bool _isValidRoute(String action) {
  return _validRoutes.contains(action);
}

void _handleShortcut(String type) {
  if (_isValidRoute(type) && navigatorKey.currentState != null) {
    // Handle valid route
    navigatorKey.currentState?.pushNamed(type);
  }
}
