Noor Flutter Package

noor is a standard, offline-first, region-aware Islamic data engine for Flutter. It is designed to be the authoritative source for prayer times, ensuring correctness across different regions and madhabs while maintaining offline capabilities.

Features

• Authoritative & Region-Aware: Prioritizes local region rules over pure mathematical calculation.
• Offline-First: Local database is the Source of Truth.
• Smart Sync: Fetches only what's needed (current + next month) and caches it.
• Offline Fallback: Automatically calculates prayer times if the API is unreachable.
• Deterministic: Same input always results in the same output.
• Hive Storage: Efficient, fast, and persistent local storage.

Getting Started

Add dependencies to your pubspec.yaml:

dependencies:
  noor:
    path: ./ # Or git/pub version
  hive_flutter: ^1.1.0

Usage

1. Initialization

Initialize the SDK before using it, ideally in your main() function.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Noor.initialize();
  runApp(MyApp());
}

2. Set Location

Configure the location to get accurate times. Changing location automatically wipes old data to ensure correctness.

// Set high-level location IDs (preferred for accuracy)
await Noor.setCountryId(1);
await Noor.setRegionId(101);

// AND/OR Set Coordinates (required for offline calculation fallback)
await Noor.setCoordinates(lat: 25.2048, lng: 55.2708);

3. Sync Data

Trigger a sync to fetch data from the API or calculate it locally.

await Noor.prayer.sync();

4. Read Prayer Times

Access the stored prayer times synchronously.

final today = Noor.prayer.today();

if (today != null) {
  print("Fajr: ${today.fajr}");      // 24h format: "05:12"
  print("Fajr: ${today.fajr12h}");   // 12h format: "5:12 AM"
  print("Isha: ${today.isha12h}");   // 12h format: "7:25 PM"
}

final nextDay = Noor.prayer.next(); // Tomorrow's times

Architecture

• Source of Truth: Hive (Local DB).
• API: Used only to populate the DB.
• Calculation: Used only as a fallback when API is unavailable.
