downgrade analysis failed failed with 6 errors:

• WRONG_NUMBER_OF_TYPE_ARGUMENTS - lib/services/chat_service.dart:83:12 - The type 'DocumentSnapshot' is declared with 0 type parameters, but 1 type arguments were given.

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
