flutterlifecyclehooks

A flutter package that lets you easily add hooks for application lifecycle state. LifecycleMixin uses the AppLifecycleListener and registers methods as hooks.

The list of hooks is:

• onAppShow
• onAppHide
• onAppRestart
• onAppResume
• onAppPause
• onAppInactive
• onAppDetach
• onExitAppRequest

Note: Read more about these lifecycle hooks https://api.flutter.dev/flutter/widgets/AppLifecycleListener-class.html

Optionally provides onContextReady that acts like initState but BuildContext is available for use.

Getting Started

Add on pubspec.yaml

dependencies:
    flutterlifecyclehooks: version

Example code

class App extends StatefulWidget {
  @override
  _AppState createState() => _AppState();
}

class _AppState extends State<App> with LifecycleMixin {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text(
            currentLifecycleState.toString(),
          ),
        ),
      ),
    );
  }

  @override
  void onAppLifecycleChange(AppLifecycleState state) {
    setState(() {});
  }

  @override
  void onResume() {
    print('did resume');
  }

  @override
  void onPause() {
    print('did pause');
  }
}

Also you can use, LifecycleHooksSubscriber wraps a widget and provides convient arguments for lifecycle hooks.

You can use this if you don't want to polute the namespace of a stateful widget.
