A simple code that break dart fix about sdk

[dart-github-bot]

Summary: The dart fix -n command crashes when run on a project containing a string with an unnecessary escape character. The crash occurs due to an error in the RemoveUnnecessaryStringEscape fix, which attempts to create both a Dart file edit and a generic file edit for the same file, leading to a state conflict.
