flutter - 当应用程序在前台时，永不调用Cloud Messaging的onMessage回调，但是会调用onResume和onLaunch吗？

Question

我实现了Firebase云消息传递，并遵循了以下教程https://www.youtube.com/watch?time_continue=304&v=2TSm2YGBT1s&feature=emb_logo。而且我大部分时间都在使用它。每当应用程序在后台或关闭时，我都会收到通知，它将打开应用程序并执行onResume或onLaunch回调。

但是我似乎无法使onMessage回调起作用。每当应用程序在前台并且我发送通知时，不会调用onMessage吗？我将以下日志发送到控制台

E/FlutterFcmService(18141): Fatal: failed to find callback
W/FirebaseMessaging(18141): Unable to log event: analytics library is missing
W/FirebaseMessaging(18141): Unable to log event: analytics library is missing

我也没有看到onBackgroundMessage被调用。

通知服务

class CloudMessagingService extends NotificationService
{
  final FirebaseMessaging firebaseMessaging = FirebaseMessaging();

  CloudMessagingService()
  {
    if(Platform.isIOS)
      firebaseMessaging.requestNotificationPermissions(IosNotificationSettings());

    firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print('I have a cloud messaging message yay');
        print('onMessage: $message');
      },
      onBackgroundMessage: (Map<String, dynamic> message) async {
        print('onBackgroundMessage: $message');
      },
      onLaunch: (Map<String, dynamic> message) async {
        print('onLaunch: $message');
      },
      onResume: (Map<String, dynamic> message) async {
        print('onResume: $message');
      },
    );
  }

  Future<void> sendNotificationToGroup(GroupModel group, NotificationType type)
  {
    print('Send ${type.valueString} notification to ${group.id}');
    return null;
  }
}

我正在使用Pixel 3XL在Android模拟器上对此进行测试

所以我仔细查看了文档，发现

Note: When you are debugging on Android, use a device or AVD withGoogle Play services. Otherwise you will not be able to authenticate.

切换到具有Playstore支持的设备后，将调用onMessage回调!
