# Basic Usage Examples
|
|
|
|
## Qibla for Multiple Cities
|
|
|
|
```dart
|
|
import 'package:qibla/qibla.dart';
|
|
|
|
void main() {
|
|
final cities = [
|
|
('New York', 40.7128, -74.0060),
|
|
('London', 51.5074, -0.1278),
|
|
('Istanbul', 41.0082, 28.9784),
|
|
('Jakarta', -6.2088, 106.8456),
|
|
('Cape Town', -33.9249, 18.4241),
|
|
];
|
|
|
|
print('City Bearing Direction Distance');
|
|
print('${'─' * 54}');
|
|
|
|
for (final (city, lat, lng) in cities) {
|
|
final bearing = qiblaAngle(lat, lng);
|
|
final dir = compassDir(bearing);
|
|
final km = distanceKm(lat, lng, kaabaLat, kaabaLng);
|
|
|
|
print('${city.padRight(18)}${bearing.toStringAsFixed(1).padLeft(6)}° ${dir.padRight(9)} ${km.toStringAsFixed(0)} km');
|
|
}
|
|
}
|
|
```
|
|
|
|
## Great-Circle Path Waypoints
|
|
|
|
```dart
|
|
import 'package:qibla/qibla.dart';
|
|
|
|
void main() {
|
|
// 8 waypoints from London to Makkah
|
|
final path = greatCirclePath(51.5074, -0.1278, kaabaLat, kaabaLng, 8);
|
|
|
|
print('Waypoints from London to Makkah:');
|
|
for (int i = 0; i < path.length; i++) {
|
|
final p = path[i];
|
|
print(' ${i + 1}. ${p.latitude.toStringAsFixed(4)}°, ${p.longitude.toStringAsFixed(4)}°');
|
|
}
|
|
}
|
|
```
