Question

对于应用程序开发，我需要Firebase云消息传递。在我的pubsepc.yaml中，添加以下依赖项：firebase_messaging：^ 5.1.6

我暂时没有添加代码。

此后，我构建代码，但出现错误：

flutter/.pub-cache/hosted/pub.dartlang.org/firebase_messaging-5.1.6/android/src/main/java/io/flutter/plugins/firebasemessaging/FlutterFirebaseMessagingService.java:143: error: method findAppBundlePath in class FlutterMain cannot be applied to given types;
    String appBundlePath = FlutterMain.findAppBundlePath();
                                      ^
  required: Context
  found: no arguments
  reason: actual and formal argument lists differ in length

Answer 1

如果您使用Java并选中FlutterFirebaseMessagingService.java

FlutterMain.findAppBundlePath()

此处需要在参数中添加上下文，因此第一种解决方案是您可以在参数中添加上下文

FlutterMain.findAppBundlePath(context)

第二个解决方案从firebase_messaging: ^5.1.6中删除了pubspac.yaml的依存关系，并在终端中打flutter clean进行清理，现在添加firebase_messaging: 5.1.6 （不带^）并在终端中点击flutter pub get。此解决方案对我有用。

第二种解决方案是更好的做法。

请尝试：flutter upgrade并做@Maddy回答

这对我有用。很抱歉，我没有足够的声誉。
