🚀 Quick Start #

Installation #

Add to your pubspec.yaml:

dependencies:
  quicui_firebase: ^1.0.0

Initialize Firebase #

import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:quicui_firebase/quicui_firebase.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Initialize Firebase
  await Firebase.initializeApp();
  
  // Initialize QuicUI Firebase plugin
  const config = FirebaseConfig(
    enableOfflinePersistence: true,
    enableRealtimeSync: true,
    syncInterval: Duration(seconds: 30),
  );
  await FirebaseInitializer.initialize(config);
  
  runApp(const MyApp());
}

Basic CRUD Operations #

final dataSource = FirebaseDataSource('users');

// Create
final userId = await dataSource.create({
  'name': 'John Doe',
  'email': 'john@example.com',
});

// Read
final user = await dataSource.read(userId);

// Update
await dataSource.update(userId, {'name': 'Jane Doe'});

// Delete
await dataSource.delete(userId);

// Stream real-time updates
dataSource.streamCollection().listen((users) {
  print('Users: $users');
});

Query Building #

final query = FirebaseDataSource('users')
    .query()
    .where('age', isGreaterThan: 18)
    .where('status', isEqualTo: 'active')
    .orderBy('createdAt', descending: true)
    .limit(10)
    .build();

final results = await query.fetch();
query.stream().listen((results) {
  print('Query results: $results');
});

Real-Time Sync #

// Setup sync manager
final syncManager = SyncManager(
  dataSource: dataSource,
  syncInterval: const Duration(seconds: 30),
);
await syncManager.initialize();

// Monitor sync state
syncManager.syncStatusStream.listen((status) {
  print('Sync status: $status');
});

// Automatic offline queue management
// Operations are queued when offline and synced when online

Callback Events #

// Register callback for document creation
FirebaseEventManager.instance.registerCallback(
  FirebaseEventType.DOCUMENT_CREATED,
  (event) {
    print('Document created: ${event.data}');
    // Trigger QuicUI actions or UI updates
  },
);

// Register with event filtering
FirebaseEventManager.instance.registerCallback(
  FirebaseEventType.DOCUMENT_UPDATED,
  (event) {
    print('User updated: ${event.metadata['collection']}');
  },
  filters: [
    CallbackFilter(
      filterType: FilterType.equals,
      field: 'collection',
      value: 'users',
    ),
  ],
);

// Available events:
// - DOCUMENT_CREATED, DOCUMENT_UPDATED, DOCUMENT_DELETED
// - COLLECTION_MODIFIED, BATCH_OPERATION_COMPLETED
// - SYNC_STARTED, SYNC_COMPLETED, SYNC_FAILED
// - CONNECTION_ONLINE, CONNECTION_OFFLINE
// - ERROR_OCCURRED, INITIALIZATION_COMPLETE, CUSTOM

🎓 Best Practices #

Initialize Early - Call FirebaseInitializer.initialize() in main()
Use Streams - Prefer streamCollection() over polling
Offline Support - Enable enableOfflinePersistence: true
Error Handling - Use try-catch for all database operations
Immutable Models - Extend Equatable for data models
Batch Operations - Use batches for multiple writes
Query Optimization - Index frequently queried fields
Monitor Performance - Use sync status callbacks to track sync health

📊 Performance Characteristics #

1000 events: <5 seconds
Event history: Max 100 events (configurable)
Offline queue: Unlimited capacity with exponential backoff
Memory usage: ~2-3 MB base + stream overhead
Sync latency: 30 seconds default (configurable)
