Fix Android OAuth2 page not being resumed properly

I've opened a PR a while back that fixes Flutter OAuth2 authentication with recent flutter_web_auth_2 version, that didn't get much attention:

• https://github.com/appwrite/sdk-generator/pull/1263

All details are in the PR description. I'm currently running my own fork of the Flutter SDK, which is somewhat inconvenient to maintain, what should I do to make this PR pass review?

Thanks!

@Namaneo hi there, a team member has left a small comment on the pr, lets address it then we can release
