Xcode 使用Firebase应用程序内消息传递插件时，Flatter无法编译项目

我成功地在android上实现了这个插件，但是当我尝试在ios上启动应用程序时，我收到了一条错误消息。当我禁用插件并在ios上重新安装应用程序时，一切正常。 这是我的控制台日志：

Launching lib/main.dart on iPhone 5s in debug mode...
Running pod install...
Warning: Podfile is out of date
  This can cause a mismatched version of Flutter to be embedded in your app, which may result in App Store submission rejection or crashes.
  If you have local Podfile edits you would like to keep, see https://github.com/flutter/flutter/issues/24641 for instructions.
To regenerate the Podfile, run:
  rm ios/Podfile

是否有人面临同样的问题并能够解决它

您可以尝试以下操作：

飘动干净

rmios/Podfile

rm ios/Podfile.lock

吊舱更新

吊舱安装

这就行了。

我修好了

在应用程序消息中评论firebase，即（#firebase在应用程序消息中：^0.1.1+3） 内部公共规范yaml

运行

flatter包获取

删除ios文件夹中的Podfile.lock

打开你的终端

cd到项目ios文件夹

输入

Vim Podfile

按“i”键进入插入模式

将这些添加到底部的行：

pod'Firebase'，'6.15.0'

pod'FirebaseInAppMessaging'，'0.16.0'

按屏幕上的“esc”
