# moon_sighting
|
|
|
|
Lunar crescent visibility for Dart and Flutter. Computes moon phase, topocentric position, illumination, and Yallop/Odeh crescent visibility criteria using Meeus algorithms. Zero dependencies.
|
|
|
|
## Quick Start
|
|
|
|
```dart
|
|
import 'package:moon_sighting/moon_sighting.dart';
|
|
|
|
final phase = getMoonPhase();
|
|
print('${phase.phaseName} (${phase.illumination.toStringAsFixed(1)}%)');
|
|
|
|
final vis = getMoonVisibilityEstimate(
|
|
DateTime.utc(2025, 3, 31, 18, 30),
|
|
21.4225, 39.8262, // Mecca
|
|
);
|
|
print('Zone: ${vis.zone.label}');
|
|
print('Visible naked eye: ${vis.isVisibleNakedEye}');
|
|
```
