找不到“firebase_messaging/FirebaseMessagingPlugin.h”文件

我正在尝试在 ios 上运行我的 flutter 应用程序，但是我收到此错误

/ios/Runner/GeneratePluginRegistrant.m:6:9： 找不到“firebase_messaging/FirebaseMessagingPlugin.h”文件

这是我的 podfile 内容

我的Xcode版本是10.0

我该如何解决它？提前致谢

如有疑问，我只是擦除并重新安装，而不是手动处理级联依赖项。

1) rm your ios/Pods dir和 Podfile.lock 文件（当然要备份）

2) rm your ~/.pub-cache/hosted/pub.dartlang.org/

3) flutter clean

4) flutter packages get

5) pod repo update

6) 像平常一样运行 flutter 可执行文件（调用 pod install），或者手动运行pod install.
