screen_interactive_detector

Flutter Plugin to detect if device is in lock screen. Useful for determining whether app entered background due to locking screen or leaving app.

Usage

Import library and call the following method.

NOTE: this plugin only works on physical device for iOS.

import 'package:screen_interactive_detector/screen_interactive_detector.dart';
...
bool? isInteractive = await ScreenInteractiveDetector.isInteractive();
}

You will probably observe the AppLifecycleState with a WidgetsBindingObserver and call this when app is in background:

@override
void didChangeAppLifecycleState(AppLifecycleState state) async {
  super.didChangeAppLifecycleState(state);
  switch (state) {
    case AppLifecycleState.resumed:
      debugPrint('app resumed');
      if (mounted) setState(() {});
      break;
    case AppLifecycleState.inactive:
      if (Platform.isAndroid) {
        _isInteractive = await ScreenInteractiveDetector.isInteractive();
        debugPrint('app inactive, is screen interactive: $_isInteractive');
      }
      break;
    case AppLifecycleState.paused:
      if (Platform.isIOS) {
        _isInteractive = await ScreenInteractiveDetector.isInteractive();
        debugPrint('app paused, is screen interactive: $_isInteractive');
      }
      break;
    case AppLifecycleState.detached:
      break;
  }
}
