Steps to reproduce

1. Have a Flutter project and run any Flutter command that triggers pub resolution (e.g., flutter pub get, flutter run, flutter build)
2. Navigate to the Flutter SDK directory:

bash   cd $(which flutter)/../..
   git status

3. Observe that pubspec.lock is marked as modified
4. Run flutter upgrade

Expected results

flutter upgrade should complete successfully without requiring --force, since the modification to pubspec.lock was made by Flutter itself — not by the user.

Actual results

Your flutter checkout has local changes that would be erased by upgrading. If you want to keep these
changes, it is recommended that you stash them via "git stash" or else commit the changes to a local
branch. If it is okay to remove local changes, then re-run this command with "--force".

Running git diff pubspec.lock inside the Flutter SDK directory shows:

diff --git a/pubspec.lock b/pubspec.lock
