Building for iOS Simulator, but the linked and embedded framework 'App.frame'

在使用android studio运行flutter项目时，报如下错误：

building for is simulator but the linked and embedded framework ‘app.framework’ was built for ios

这是什么问题呢？其实是项目中已经存在的App.framework和当前编译的模式不一致。解决的办法很简单：

删除 ios/Flutter/App.framework

然后运行项目，会重新生成App.framework，问题解决！
