Seems dart fix --apply on single file is not supported on Dart SDK version 2.16.1

Related to dart-lang/sdk#43892

[hyiso]

Find that dart fix --apply for single file is supported since Dart SDK 2.18.0（Flutter SDK 3.3.0） dart-lang/sdk@467a1b0

[hyiso]

This can be fixed with 84aaa60

Now change lint_staged configuration in pubspec.yaml to

lint_staged:
  .dart: dart fix --apply <file>/../

lint_staged will lint the parent path for this file.
