How to build flutter web app in debug mode?

Question

flutter build web will build my flutter app with obfuscation and minification.

I want my error stack to be readable though.

How should I modify

Answer 1

Try:

flutter build web --profile --dart-define=Dart2jsOptimization=O0

See:

Answer 2

The only way I have found to do this is to use flutter run -d chrome. We would then need to locate where the files on disk are located.
