Hi I am trying to run flutter build web --no-sound-null-safety but I am getting the below error. I followed the following steps :

  1. after running flutter build web --no-sound-null-safety I got the error
  2. On looking at various forums I ran flutter upgrade
  3. After upgrade I ran flutter clean and flutter pub get but the error still persists.
  4. Also ran flutter doctor -v but not getting any errors.
  5. checked the location of the file and it is correct but still not able to find the location -- even though no changes was made to any of the location it suddenly started showing the error

If someone can please help me resolve this issue.

Let me know if you require any further information from my end.

error on running the above:

Target dart2js failed: Exception: Warning: The 'dart2js' entrypoint script is deprecated, please use 'dart compile js' instead. lib/providers//login_details.dart:1:8: Error: Error when reading 'lib/providers/models/login_page.dart': Error reading 'lib/providers/models/login_page.dart' (No such file or directory) import '../models/login_page.dart';

Flutters say it cant find "login_page.dart';" this one.

You will follow simple steps.

Your dart page top import first -- import '../models/login_page.dart';
