To learn more about code review, see our documentation on Tree Hygiene: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md --> This PR removes a check that looks for the use of Flutter version related Dart define keys in the environment variables (not Dart defines) of the user of the Flutter tool. We don't need to check the environment variables, we only need to check the user defined Dart defines. Here's how it currently works: 1. User builds a Flutter app via tool 2. tool checks environment variables for Flutter version related Dart define keys and throws if it finds and (_and_) 3. tool checks list of user defined Dart defines for Flutter version related Dart define keys and throws if it finds any This PR removes the check in step 2, since step 3 is what we actually care about. The `FLUTTER_GIT_URL` environment variable is set on forks and the Dart define is used to make that information available to applications at runtime. However, environment variables don't propagate to be Dart defines, thus the above mentioned check is not needed. *List which issues are fixed by this PR. You must list at least one issue.
