Linux repo_checks failure: tool unit tests failing with missing trailing newlines #182842
Description
The Linux repo_checks build failed during the tool unit tests step. Several tests are failing because the generated pubspec.yaml content is missing trailing newlines.
Expected: '...dependencies:\n flutter:\n sdk: flutter\n\n\n\n'
Actual: '...dependencies:\n flutter:\n sdk: flutter'
Which: is different. Both strings start the same, but the actual value is missing the following trailing characters: \n\n\n
Failed Build: Linux repo_checks 22065
Logs: stdout
