Not really specific to Supabase but just Flutter Web in general or I was just not able to find out how to handle it well when I faced some issues. These are what I can remember: - I was not able to use "io" library for Flutter Web so uploading images were not possible, it would just give me a weird exception. But I think you're familiar with that since you've been with Flutter - I tried to implement Google OAuth, but I was having problems with how router works in Flutter and the package I was using, so the redirect URL never works for me because I always end up going to the initial route of what I defined (StartupView; This is where I initalize my AuthService to handle saved auth token and redirect to HomeView). So if Google OAuth via web does not work then other OAuth providers wouldn't work for Flutter Web in my case - Also I noticed that having child routes looked kinda weird on Mac, because of the CupertinoPage having a shadow so my side menu bar looked weird. But then I found out some workaround to disable the Cupertino via ThemeData

You can use uploadBinary on flutter web

Is that a package?

it's supabase storage client method. There's example here https://github.com/phamhieu/supabase-flutter-demo/blob/04dfeed34af0e43222faf5d9d02b90508056dcb4/lib/screens/profile_screen.dart#L104-L106

Ah...... I see. I was able to parse the image object to binaries but didn't check about other upload image methods available Thanks @User
