I'm trying to build in production mode my flutter app for web, but I have my "main.dart" file not in the root lib directory, this cause to not be able to build my app for web, I have tried to point the path to where the "main.dart" file is, like:

flutter build web path/to/my/main/file/main.dart --release

But ended out with an error message like:

 Building with sound null safety 

Compiling lib/main.dart for the Web...                          
Target dart2js failed: Exception: .dart_tool/flutter_build/72a548668e340c281af31f7867ace19b/main.dart:8:8:

       ^

             ^^^^
Error: Compilation failed.

This command works when you try to build an APK, but not to build a flutter web app.

Can somebody please tell me how to solve this?

add -t before your main.dart path.

eg.

flutter build web -t lib/main-dev.dart
