flatter_local_notifications路由全屏

Question

flatter_local_notifications

我用FCM后台消息创建全屏功能。

当我收到通知时，主页被带到前面，这个功能被声明为

如何在触发时强制切换到另一个页面？

Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
// print("myBackgroundMessageHandler message: $message");
int msgId = int.tryParse(message["data"]["msgId"].toString()) ?? 0;
// print("msgId $msgId");
_showFullScreenNotification();
}

Future<void> _showFullScreenNotification() async {
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails('your other channel id',
'your other channel name', 'your other channel description',
sound: RawResourceAndroidNotificationSound('slow_spring_board'),
priority: Priority.high,
importance: Importance.high,
fullScreenIntent: true);
const IOSNotificationDetails iOSPlatformChannelSpecifics =
IOSNotificationDetails(sound: 'slow_spring_board.aiff');
const MacOSNotificationDetails macOSPlatformChannelSpecifics =
MacOSNotificationDetails(sound: 'slow_spring_board.aiff');
const NotificationDetails platformChannelSpecifics = NotificationDetails(
android: androidPlatformChannelSpecifics,
iOS: iOSPlatformChannelSpecifics,
macOS: macOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(
0,
'custom sound notification title',
'custom sound notification body',
platformChannelSpecifics);
}
