I am trying upload image in Supabase Storage and I am using this method as in document :

supabase.storage.from('avatars').upload(fileName,file)

Here file is : var file = File(_session.photoFilePath!) // import'package:universal_io/io.dart'

and _session.photoFilePath! in print() is: blob:http://localhost:55914/eff9c2bb-061f-4577-bf00-eff523029635

also _session.photoFileName! in print() is: tiger.jpeg

I am already signedIn and I have permission upload image in avatars budget. When I run without any error or warning that supabase.storage.from('avatars').upload(_session.photoFileName!, file)

I got this error :

As i understand , It happens because of the file library. I can't use 'dart:io' because it's not available for Flutter Web. Supabase upload image method accepts file from 'package:universal_io/io.dart' from universal_io: ^2.0.4 and when run upload file function, this problem happen. Do you any idea about how I can solve this problem and how I can upload supabase storage ?

I have the same problem. Unable to upload blobs. When I try to convert the blob to File, I get the following errors:
