Error initializing on Flutter Web

[chiefheru]

Describe the bug Hi, I have followed the instructions on the site to add supabase_flutter to a new Flutter web project and I get an error initializing. I also noticed that when I run the command flutter pub add supabase_flutter it adds the version ^1.0.1 to pubspec.yaml rather than the latest (2.7.0). When I try to manually use the 2.7.0, I get this versioning error.

Resolving dependencies...
Because supabase depends on supabase_flutter 2.7.0 which depends on supabase 2.4.0, supabase 2.4.0 is required.
So, because supabase is 1.0.0+1, version solving failed.

You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on supabase_flutter: flutter pub add supabase_flutter:^1.0.1
exit code 1

This is the error when I run the project

../../.pub-cache/hosted/pub.dev/supabase_flutter-1.0.1/lib/supabase_flutter.dart:6:1: Error: Error when reading 'lib/supabase.dart': No such file or
directory
export 'package:supabase/supabase.dart';
^
../../.pub-cache/hosted/pub.dev/supabase_flutter-1.0.1/lib/src/supabase.dart:3:8: Error: Error when reading 'lib/supabase.dart': No such file or directory
import 'package:supabase/supabase.dart';
       ^
../../.pub-cache/hosted/pub.dev/supabase_flutter-1.0.1/lib/src/supabase.dart:80:8: Error: Type 'SupabaseClient' not found.
  late SupabaseClient client;

To Reproduce Steps to reproduce the behavior:

1. create a new flutter web project (flutter create --platforms web test)
2. flutter pub add supabase_flutter
3. add import 'package:supabase_flutter/supabase_flutter.dart'; to main.dart
4. initialize supabase in main() method
5. Run the project using flutter run -d chrome
6. get error in terminal

This is the flutter doctor output

You can't name your package supabase, because that's already the name of our dart supabase package, which supabase_flutter is based on. So by changing the name: field in your pubspec.yaml, this should be fixed.
