DeviceGeolocationMock class

In-memory fake of DeviceGeolocationPlatform for use in tests.

Apps depending on device_geolocation can import this class from package:device_geolocation/testing.dart and install it as the active platform implementation, removing the need to set up mock method channels manually.

import 'package:device_geolocation/device_geolocation.dart';
import 'package:device_geolocation/testing.dart';

void main() {
  late DeviceGeolocationMock mock;

  setUp(() {
    mock = DeviceGeolocationMock.install();
  });

  tearDown(() => mock.reset());

  test('returns the position configured by the test', () async {
    mock.position = mock.makePosition(latitude: 41.0, longitude: 2.0);
    final p = await DeviceGeolocation.getCurrentPosition();
    expect(p.latitude, 41.0);
  });
}
