Hi @hufwin I'll take a look at it. Right now it seems we have to switch to another package (https://pub.dev/packages/flutter_web_auth) as web is not yet supported in the package from the examples.. It has to support custom schemes for redirects
I've created a flutter example with flutter_web_auth_2 using PKCE here https://github.com/zitadel/zitadel_flutter I've tested web on localhost, IOS is also working.. You can take a look in the meantime, but we still have to add storage and check support for mac, windows, and android
