The most sophisticated cross-platform background location-tracking & geofencing module with battery-conscious motion-detection intelligence

import BackgroundGeolocation, {
  type Location,
  type GeofenceEvent
} from 'react-native-background-geolocation';


// callbacks should see the bridged types

});

  console.log(gfEvent.identifier, gfEvent.location.coords.longitude);
});

// Ensure that invalid usage fails if uncommented:
// BackgroundGeolocation.onLocation((location) => {
//   const bad: string = location; // should be type error
// });
