Final Provider Fix - Riverpod 3.0 Compatibility

✅ Issue Resolved

The provider was updated to work with the latest Riverpod 3.0 code generation.

🔧 Changes Made

Before (Custom Ref Types)

import 'package:riverpod_annotation/riverpod_annotation.dart';
import '../../domain/entities/price_document.dart';

part 'price_documents_provider.g.dart';

@riverpod
List<PriceDocument> priceDocuments(PriceDocumentsRef ref) {
  return _mockDocuments;
}

@riverpod
List<PriceDocument> filteredPriceDocuments(
  FilteredPriceDocumentsRef ref,
  DocumentCategory category,
) {
  final allDocs = ref.watch(priceDocumentsProvider);
  return allDocs.where((doc) => doc.category == category).toList();
}

Issue: Using custom ref types PriceDocumentsRef and FilteredPriceDocumentsRef which are not compatible with Riverpod 3.0 generated code.

After (Standard Ref Type) ✅

import 'package:riverpod_annotation/riverpod_annotation.dart';
import '../../domain/entities/price_document.dart';

part 'price_documents_provider.g.dart';

@riverpod
List<PriceDocument> priceDocuments(Ref ref) {
  return _mockDocuments;
}

@riverpod
List<PriceDocument> filteredPriceDocuments(
  Ref ref,
  DocumentCategory category,
) {
  final allDocs = ref.watch(priceDocumentsProvider);
  return allDocs.where((doc) => doc.category == category).toList();
}

Solution: Use the standard Ref type from riverpod_annotation package.

📋 Key Points

1. Ref Type Usage

✅ Use Ref from riverpod_annotation (NOT custom types)
✅ Works with both simple and family providers
✅ Compatible with Riverpod 3.0 code generation

2. Generated Code

The build runner now generates Riverpod 3.0 compatible code:

// New Riverpod 3.0 pattern
final class PriceDocumentsProvider
    extends $FunctionalProvider<List<PriceDocument>, ...>
    with $Provider<List<PriceDocument>> {
  // ...
}

This is the correct generated format for Riverpod 3.0+.

3. Pattern Matches Project Convention

Other providers in the project using the same pattern:

✅ lib/features/loyalty/presentation/providers/gifts_provider.dart
✅ lib/features/favorites/presentation/providers/favorites_provider.dart

✅ What Works Now

Basic Provider

// Provider definition
@riverpod
List<PriceDocument> priceDocuments(Ref ref) {
  return _mockDocuments;
}

// Usage in widget
final documents = ref.watch(priceDocumentsProvider);

Family Provider (with parameter)

// Provider definition
@riverpod
List<PriceDocument> filteredPriceDocuments(
  Ref ref,
  DocumentCategory category,
) {
  final allDocs = ref.watch(priceDocumentsProvider);
  return allDocs.where((doc) => doc.category == category).toList();
}

// Usage in widget
final policyDocs = ref.watch(
  filteredPriceDocumentsProvider(DocumentCategory.policy),
);
