问题
This shows when I try to run the code without changing any word
it gives me an error in android studio, and when I run flutter doctor it shows flutter and dart plugins are not installed but it is, when I asked that on stack overflow others told me it can be safely ignored I don't know what to do
the question where I asked that Flutter doctor: Flutter and dart plugins not installed
Launching lib\main.dart on Device in debug mode...
