我在从 pub.dev 安装新包时遇到了一些问题。我使用以下命令在我的根项目中创建自己的包:flutter create --template=package main_template结构文件夹
我在里面安装新包 main_template 不是 库 .每次在 中安装新包main_template 我收到此错误:
Compiler message:

Try correcting the name to the name of an existing method, or defining a method named 'DeviceInfoPlugin'.

Until now i trying install 3 package [Cache Network Image,Device Info , SplashScreen]. And all packages give me that error.
我怎样才能修好它？
最佳答案
你用的是vs代码吗？
只需重新启动或关闭 vs 代码应用程序(所有窗口)，然后再次打开它运行
