ImageProvider generated as InvalidType

[yakou32]

Bug description
I'm using Flutter Riverpod 2.4.9 to generate an ImageProvider object (either FileImage, AssetImage, NetworkImage...), according to some variable.

The generator doesn't compile correctly, the ImageProvider type being replaced by InvalidType.

To Reproduce

Here is a simplified code to reproduce:

// test.dart

import 'package:flutter/material.dart';
import 'package:riverpod_annotation/riverpod_annotation.dart';

part 'test.g.dart';

@riverpod
ImageProvider testImage(TestImageRef ref) {
  return const AssetImage('some_valid_path');
}

Expected behavior
The generated file should look like
final testImageProvider = AutoDisposeProvider<ImageProvider>.internal(...
instead of
final testImageProvider = AutoDisposeProvider<InvalidType>.internal(...

Workaround
At the moment, I replace the current type by hand in the generate file.

It is obviously a tedious task; best would be to fix the ImageProvider compatibility issue instead.

Is it because the object class name ImageProvider would interfere with any Riverpod logic?

Have you tried Raw<ImageProvider>?

Thanks @snapsl I was not aware of that Raw type.

However, it doesn't solve the issue.
Indeed, in the simplified example, there is no Stream nor Future that Raw would disable...

This is a known issue with various types.
Only 3.0 fixes the issue, and the fix won't be added to 2.0

That's great!

Thank you so much Rémi!
