Unable to compile flutter app on new setup

Question

I have newly setup the flutter, but the sample app does not compile. Flutter doctor also show everything is setup properly.

Following is the error:

Answer 1

Just had a similar issue. In my case there was a type in one of the imports.I had "F" instead of "f" in one if the import files. Just double check all the imports (cases, spaces, underscores, etc) thoroughly .

Answer 2

It seems the cache folder for your flutter installation is broken.

You can do steps below in Terminal command line :

rm -rf /Users/XXX/flutter/bin/cache (XXX is Mac user)

flutter doctor -v

flutter run --release
