🧠 Synrg #

Synrg is a comprehensive Flutter utility package that abstracts and unifies Firebase services, modular state management, data modeling, query building, UI feedback, and validation — all with developer experience in mind.

It provides an opinionated architecture for building scalable Flutter apps with:

• Firebase (Auth, Firestore, Storage, Functions, Remote Config, Realtime DB, Analytics, Crashlytics, Performance)
• BLoC integration with enhanced state and UI feedback
• Strongly typed indexing, validation, and serialization logic
• Production-ready UI modal system
• 150+ domain-specific validators

✨ Features #

• ✅ SynrgBlocProvider with automatic modal display and analytics
• 🔐 Firebase Authentication & profile management
• 🗃 Firestore abstraction with SynrgIndexer and paginated querying
• ⚡ Cloud Functions typed wrapper with result status
• 📁 Firebase Storage simplified upload/download/delete
• 🌐 Firebase Remote Config wrapper
• 🔄 Realtime Database write, update, listen and delete
• 📊 Firebase Analytics & Performance tracing
• 🛠 Crashlytics error logging and custom attributes
• 🔎 Query builder (QueryFilter) and parser
• 📦 Abstract base class SynrgClass for ID, map, and parent tracking
• 🧪 Extensive validation library for IDs, formats, geo, finance, healthcare, etc.

📦 Installation #

Add dependency

flutter pub add synrg

Add synrg to your pubspec.yaml:

dependencies:
  synrg: ^latest

Make sure to initialize Firebase in your project.

🚀 Getting Started #

import 'package:synrg/synrg.dart';

void main() async {
  await Firebase.initializeApp();

  SynrgCrashlytics.instance.initialize();
  SynrgAuth.initialize(profileIndex);
}

🧩 Modules #

1. SynrgBlocProvider #

A wrapper over BlocProvider + BlocConsumer that listens for modals and analytics automatically.

SynrgBlocProvider<MyBloc>(
  bloc: MyBloc()..add(MyInitEvent()),
  builder: (context, state) {
    if (state is MyStateReady) {
      return MyPage();
    }
    return CircularProgressIndicator();
  },
);

Requires states to extend SynrgState:

class MyState extends SynrgState {
  const MyState({this.modal}) : super(modal: modal);
  final SynrgModal? modal;

  @override
  Map<String, dynamic> toMap() => {...};
}

2. SynrgModal #

Show toasts, dialogs, drawers, etc., based on state.

emit(MyState(modal: SynrgModal(
  message: 'Operation failed',
  level: AlertLevel.error,
  type: SynrgModalType.toast,
)));

3. SynrgAuth #

Firebase Authentication + Profile sync

await SynrgAuth.instance.signIn(email, password);
final user = SynrgAuth.instance.profile;

4. SynrgIndexer<T> #

Typed Firestore access

final index = SynrgIndexer<Project>('projects', Project.fromMap);

final project = await index.get('id123');
await index.save(Project(name: 'New Project'));

Supports pagination, filtering, and batch ops.

5. SynrgFunction<T> #

Cloud Functions with result status:

final fn = SynrgFunction<Project>('getProject', Project.fromMap);
final result = await fn.call({'id': 'abc'});

if (result.status == SynrgFunctionStatus.success) {
  print(result.result?.name);
}

6. SynrgStorage #

final url = await SynrgStorage.instance.uploadFile('path/file.png', file);
await SynrgStorage.instance.deleteFile('path/file.png');

7. SynrgRealtimeDatabase #

await SynrgRealtimeDatabase.instance.writeData('users/1', {'name': 'Ana'});
final snapshot = await SynrgRealtimeDatabase.instance.readData('users/1');

8. SynrgRemoteConfig #

await SynrgRemoteConfig.instance.initialize();
final showBanner = SynrgRemoteConfig.instance.getBool('show_banner');

9. SynrgCrashlytics #

SynrgCrashlytics.instance.logError(error, stackTrace);
SynrgCrashlytics.instance.setUserIdentifier(userId);

10. SynrgPerformance #

final trace = await SynrgPerformance.instance.startTrace('my-trace');
// ... do work
await SynrgPerformance.instance.stopTrace(trace);

11. SynrgAnalytics #

SynrgAnalytics.instance.logEvent('screen_view', {'page': 'home'});

12. QueryFilter #

Query utilities for SynrgIndexer:

final filters = [
  QueryFilter('status', isEqualTo: 'active'),
  QueryFilter('price', isLessThanOrEqualTo: 100),
];
await index.query(filters);

Supports .toString() and .fromString(...) for dynamic queries.

13. SynrgClass #

Your models should extend SynrgClass for auto-saving and ID handling:

class Project extends SynrgClass {
  final String name;

  Project({required this.name, super.id});

  @override
  Map<String, dynamic> toMap() => {'id': id, 'name': name};

  factory Project.fromMap(Map<String, dynamic> map) =>
      Project(name: map['name'], id: map['id']);
}

🧪 Validation #

Import validators from synrg/validators.dart for:

• 📍 Address & Location (zip, city, lat/lng, etc.)
• 💳 Finance (credit card, CVV, IBAN, etc.)
• 📆 Date & Time (HH:mm:ss, timestamp, etc.)
• 📦 Logistics (SKU, barcode, VIN, tracking)
• 🧬 Healthcare (blood type, allergies, medical IDs)
• 🎓 Education (student ID, GPA, course code)
• 🌍 Tech & Network (IPv4/6, MAC, URL, domain, regex, JSON)
• 📄 Files & Content (file size, extension, CSV, Markdown, etc.)

Example:

TextFormField(
  validator: validateEmailAddress,
)

🔧 Requirements #

• Flutter 3.16+
• Firebase (initialized in your app)
• BLoC (optional but recommended)
