Could not run Flutter project. Could not find an option named “dart-define”

Question

I have a Flutter project and I have run it, everything is fine for a moment. But after some run, an error occurred. I cannot run my flutter project again, this is the error message

Could not find an option named "dart-define".

Run 'flutter -h' (or 'flutter <command> -h') for available flutter commands and options.

How to fix this error? Thanks!

Answer 1

I have found the problems, I accidentally rename my Flutter SDK to "flutter ". So I just rename my Flutter SDK back to "flutter" and restart my Android Studio.

Answer 2

In my case, this solution now works.

I solved this issue by reinstalling the Flutter SDK and restarting Android Studio.
