riverpod_generator does not respect import aliases

[sgowda97]

I have a provider where I am importing three packages, all of which has a class with same name. I imported them with alias using 'as' prefix.

The code generator is not generating the code with the said prefix.

To Reproduce

import 'package:keyzane/model/entity/user.dart' as entity;

@riverpod
class InitStreamChat extends _$InitStreamChat {
  @override
  FutureOr<void> build(entity.User currentUser, TokenResponse tokenResponse) {}
}

abstract class _$InitStreamChat
    extends BuildlessAutoDisposeAsyncNotifier<void> {
  late final User currentUser;
  late final TokenResponse tokenResponse;

  FutureOr<void> build(
    User currentUser,
    TokenResponse tokenResponse,
  );
}

Expected behavior
Instead of late final User currentUser;, it should be late final entity.User currentUser;.

3.0.0 improves this.

I don't plan on making further changes for this until we have macros.
