    Your pubspec seems quite complicated. I'd get rid of all those dependency overrides, then try to use the latest version of each needed package, then fix the code to adapt to the changes in the packages, instead of trying to override things that maybe can't be really overriden Commented Jun 8, 2024 at 13:40
  • you are right , that is what i did , and no more error , thx Commented Jun 8, 2024 at 14:24
  • now when i am adding those : cloud_functions_web: ^4.6.16 cloud_functions: ^5.0.0 i got another error ./../../.pub-cache/hosted/pub.dev/cloud_functions_web-4.9.7/lib/cloud_functions_web.dart:1:1: Error: The specified language version is too high. The highest supported language version is 2.19. // ignore_for_file: require_trailing_commas Commented Jun 8, 2024 at 14:42
  • Is there any reason why your flutter and dart version are outdated? I see that Flutter is 3.7 and Dart 2.19, while the latest are 3.22 and 3.4.1 I'm guessing here, but maybe the latest versions of those packages won't work with older dart version... Commented Jun 10, 2024 at 8:38

Run flutter pub get to download and install the updated dependencies.

Also, If you have flexibility with your project's requirements, consider downgrading Flutter to a version compatible with your current dependencies. Check the documentation for each dependency to find a compatible Flutter version.
