Unfortunately the previous way to sign in to google drive was deprecated last year: https://developers.google.com/identity/protocols/oauth2/resources/oob-migration so I've migrated to google_sign_in which does not support windows or linux right now.

I would suggestion just syncing your google drive files locally and accessing it through the file system.

If somebody is interested in implementing it, I'd be happy to assist.. Unfortunately I don't have access to a windows/linux system right now.

@hpoul thank you for your quick response. That oob-migration has killed a few tools by now 🗡️ .

I have just taken a small look at the problem and i think we could solve this by using https://pub.dev/packages/flutter_web_auth_2 in a custom google_sign_in platform interface implementation.

Ok if tested it and this indeed works. When i have more time i will make a clean implementation and make a pull request
