Generator adds comment into version controlled source file containing the Openapi annotation

[thomasgi1]

Description of the bug

Every time, when the OpenAPI generator runs, it adds following comment line to the source file containing the Openapi annotation:

// Openapi Generator last run: : 2024-02-01T14:45:00.661335

Since that source file is typically under source control its automatic modification is very annoying, because a developer has either to revert the git change or commit it after each dart run build_runner build. The situation becomes even worse, if the dart run build_runner build is executed each time before the normal flutter build.

Steps to reproduce

execute dart run build_runner build

Expected behavior

The source file containing the openapi annotation is not touched.

I have the same issue.
I've submitted a PR (#139) to allow optional updates to the annotated file.

And also, as a temporary workaround, I've created a script that removes timestamp comment using rps.

pubspec.yaml:

scripts:
  gen-apiclient:
    $script: dart run build_runner build --delete-conflicting-outputs --build-filter='lib/my_generator_config.dart'
    $after: $remove-timestamp
  remove-timestamp:
    $script:
      $windows: powershell -Command "(Get-Content lib\my_generator_config.dart) -notmatch '^\/\/ Openapi Generator last run' | Foreach-Object { $_ + \"`n\" } | Set-Content lib\my_generator_config.dart -NoNewline"
      $default: sed -i '' '/^\/\/ Openapi Generator last run/d' lib/my_generator_config.dart

I would like to add that this also causes issues when running dart run build_runner watch. Each time the generator runs, the timestamp is updated causing the watch command to trigger the generation again, resulting in an infinite loop.

If you don't need to rebuild the API everytime the build runner runs, then add this to your build.yaml:

targets:
  $default:
    builders:
      openapi_generator:
        enabled: false

if you add a new spec or need to update, just set enabled: true.

Hope this helps!

Thank you for the hint. It seems my case is one of "you are not using it correctly".

I would still prefer that the tool would not touch my manually written files. IMO it would be better to write this comment into one of the generated files instead.
