如何在接收基于Flutter构建的FCM推送通知时修复应用程序崩溃 [英] How to fix app crash on recieving FCM Push Notification built on Flutter

问题描述

我已经在Flutter上构建了一个应用，并试图通过FCM发送推送通知.之前它可以正常工作，但是在更改Firebase消息传递的版本后，一旦我发送了推送通知，该应用就会崩溃.

I have built an app on Flutter and was trying to send Push Notifications through FCM. Earlier it was working but after changing the version of Firebase messaging the app crashes as soon as I send a push notification.

我尚未对《守则》进行任何更改.我调查了GitHub问题，但无法解决.

I haven't made any changes in the Code per se. I looked into the GitHub issues but couldn't resolve it.

这是我在main.dart文件中一直使用的代码.

This is the code I have been using in the main.dart file.

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();

  void initState() {
    super.initState();

    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) {
        print('on message $message');
      },
      onResume: (Map<String, dynamic> message) {
        print('on resume $message');
      },
      onLaunch: (Map<String, dynamic> message) {
        print('on launch $message');
      },
    );
    _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(sound: true, badge: true, alert: true));
    _firebaseMessaging.getToken().then((token){
      print(token);
    });

我的firebase_messaging依赖项

My firebase_messaging dependency

  firebase_messaging: ^1.0.2

我还更改了app/build.gradle中的google-services版本

I had also changed the version of google-services in app/build.gradle

dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:3.2.0'
    }

这是添加到AndroidManifest.xml文件中以进行通知的部分

This is the part added to the AndroidManifest.xml file for notifications

 <intent-filter>
     <action android:name="FLUTTER_NOTIFICATION_CLICK" />
     <category android:name="android.intent.category.DEFAULT" />
 </intent-filter>

有人可以帮我吗?预先感谢.

Can anyone help me with this? Thanks in advance.

推荐答案

打开android项目.

Open the android project.

进入firebase_messaging的build.gradle

Go the build.gradle of firebase_messaging

在依赖项中，将 api'com.google.firebase:firebase-messaging:18.0.0'更改为 api'com.google.firebase:firebase-messaging:17.3.3'

In the dependencies change api 'com.google.firebase:firebase-messaging:18.0.0' to api 'com.google.firebase:firebase-messaging:17.3.3'

确保您使用的是pubspec.yaml中所有云依赖项的最新版本

Make sure you are using the latest version of all the cloud dependencies in pubspec.yaml
