have same error

[R0ya1Eag1e]

temporarily fixed this, opened BackgroundWorker.kt and WorkmanagerPlugin.kt in \AppData\Local\Pub\Cache\hosted\pub.dev\workmanager-0.5.2\android\src\main\kotlin\dev\fluttercommunity\workmanager and commented this lines:
in BackgroundWorker.kt: 14 and 98
in WorkmanagerPlugin.kt: from 34 to 52

it seems like android embedding method v1 is no longer supported by flutter and this lines can be deleted

This might be a duplicate of: #564

You can add workmanager from the main branch directly, as it no longer has the v1 fallbacks.

  workmanager:
    git:
      url: https://github.com/fluttercommunity/flutter_workmanager.git
      path: workmanager
      ref: main

This seems to work but it feels wrong to not have a pinned release version. Would opening an issue on the community repo be a bad idea. From the README.md of that repo it looks like flutter_workmanager doesn't have a maintainer. Is this correct?

I'm new to flutter, I am not sure how to request a new build to pub.dev

fixed with 0.6.0
