【问题描述】：

为什么我的 firebase 没有在前台/应用程序打开时显示通知，而是在 func.

我在 main() 里面的 main.dart 上有这个

 FirebaseMessaging.onMessage.listen((RemoteMessage message) {
    print('Got a message whilst in the foreground!');
    print('Message data: ${message.data}');

    if (message.notification != null) {
      print('Message also contained a notification: ${message.notification}');
    }
    FlutterAppBadger.updateBadgeCount(1);
  });

在调试控制台上

D/FLTFireMsgReceiver( 4139): broadcast received for message
I/flutter ( 4139): Got a message whilst in the foreground!
I/flutter ( 4139): Message data: {}
I/flutter ( 4139): Message also contained a notification: Instance of 'RemoteNotification'
2
W/FirebaseMessaging( 4139): Unable to log event: analytics library is missing

您应该使用 https://pub.dev/packages/flutter_local_notifications 之类的包或其他包在屏幕上显示您的通知。这是 onListen 方法上 flutter_local_notifications 的一个简单示例。

FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
FirebaseMessaging.onMessage.listen((RemoteMessage message) {
print('Got a message whilst in the foreground!');
print('Message data: ${message.data}');

if (message.notification != null) {
  flutterLocalNotificationsPlugin.show(
      notification.hashCode,
      notification.title,
      notification.body,
      NotificationDetails(
          android: AndroidNotificationDetails(
            channel.id,
            channel.name,
          ),
          iOS: const IOSNotificationDetails()),
    );
  print('Message also contained a notification: ${message.notification}');
}
FlutterAppBadger.updateBadgeCount(1);

});
