@fryette Hello! I was wondering if you could review this diff for the new version.

This PR is now almost a year old. I think I just encountered this problem (cant set a cookie on android). So I guess the project is dead?

You can use my code. Just put this into pubspec.yaml:

  webview_cookie_manager:
    git:
      url: https://github.com/m-ochyra/webview_cookie_manager.git
      ref: feature/add-flush-for-android
