当应用程序被杀死时，Flutter 本地通知不会重定向到相关屏幕

Question

我在 Flutter 应用程序中使用 flutter_local_notifications 在特定时间安排通知。

当我点击通知时，应用程序运行它按预期工作并进入相关屏幕；但是当应用程序被杀死时点击通知时，它会转至主屏幕。

由于此通知是自动安排的，而不是在 user-action 上安排的，所以我是在一个函数中而不是在一个小部件中进行的。所以，我没有context。为了解决这个问题，我使用 NavigatorState 类型的 GlobalKey。

final GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();
navigatorKey.currentState?.push(MaterialPageRoute(builder: (ctx) {
  return Scaffold(
    appBar: AppBar(
      title: Text('notification clicked'),
    ),
  );
}));

我尝试的第二种方法是使用有状态小部件

class Noti extends StatefulWidget {
  const Noti({Key? key}) : super(key: key);
  @override
  NotiState createState() => NotiState();
}

class NotiState extends State<Noti> {
  @override
  void initState() {
    super.initState();
    initNotification();
  }

  Future initNotification() async {
    const AndroidInitializationSettings initializationSettingsAndroid =
        AndroidInitializationSettings('bolt');
    final InitializationSettings initializationSettings =
        InitializationSettings(android: initializationSettingsAndroid);

    flutterLocalNotificationsPlugin.initialize(
      initializationSettings,
      onSelectNotification: selectNotification,
    );
    const notDetails = NotificationDetails(
        android: AndroidNotificationDetails('1', 'Scheduled Review',
            channelDescription: 'Review reminders at scheduled time'));
    flutterLocalNotificationsPlugin.periodicallyShow(1, 'Scheduled Review',
        'Every Minute', RepeatInterval.everyMinute, notDetails);
  }

  Future selectNotification(String? payload) async {
    Navigator.push(context, MaterialPageRoute(builder: ((ctx) {
  return Scaffold(
    appBar: AppBar(
      title: Text('notification clicked'),
    ),
  );
})));
  }

  @override
  Widget build(BuildContext context) {
    return Container();
  }
}

我将这个 Noti 小部件插入到我主页的随机位置，以便它的 initState 被调用。

同样的事情也发生在这里；即，当应用程序死机时单击通知，我将被重定向到主屏幕，而不是标题为 notification clicked 的屏幕，就像这里的逻辑一样。当应用程序处于活动状态时，它可以正常工作。我在上述库的两个版本 8.2.0 和 9.0.0 上都试过了。

没看到这条留言：

Note: from version 4.0 of the plugin, calling initialize will not trigger the onSelectNotification callback when the application was started by tapping on a notification to trigger. Use the getNotificationAppLaunchDetails method that is available in the plugin if you need to handle a notification triggering the launch for an app e.g. change the home route of the app for deep-linking.

在 notificationAppLaunchDetails 的基础上更改 initialRoute 解决了它。

final NotificationAppLaunchDetails? notificationAppLaunchDetails =
      await flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails();
  final didNotificationLaunchApp =
      notificationAppLaunchDetails?.didNotificationLaunchApp ?? false;
final initialRoute = didNotificationLaunchApp ? '/second' : '/first';
