我在应用的聊天功能中使用了流聊天。我在其中实现了通知。
所以当我在后台收到通知时

FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);

• 上面是我在main.dart中调用的函数。
• 下面是后台消息的处理程序。

Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
  showLog("firebaseMessagingBackgroundHandler message ===> ${message.data}");
  await Firebase.initializeApp();
  
  final chatClient = StreamChat.of(context).client; //in this line I need context but I can't pass the argument.
  try {
    showLog("in background message received");

    showStreamNotification(message, chatClient);
  } catch (e) {
    showLog(e.toString());
  }
}
