This problem always confronts me, no matter what I try to do or what code I write, what is the solution?

Always only when I turn on the device for the first time does the simulator work so even if I stopped programming, I would keep the simulator open for days until I finish the code because if I close it will not work again and I will not see my code result. it's for me a big problem please help me

Open the xcworkspace file in Xcode. Select products and click on clean build folder. Clear the warnings if you get any. Run the app from Xcode. Once its successfully built from Xcode you should be able to run it from your IDE too

CodePudding user response：

Of course it's good to know what is going on in native code as well (ios). However if you just starting with Flutter and do not want to do anything with XCode there is one really easy way how to fix it.

Just create new flutter project using terminal commend flutter create <project_name>

And copy the ios folder from this new project to your existing one where you have this problem. Then it should work.

This way is a little bit problematic if you made some changes in native code e.g: you changed your info.plist file. Then you do not have these changes any more - then you should consider fix it using XCode.
