GeofencesChangeEvent¶
Geofence monitoring change delivered to BackgroundGeolocation.onGeofencesChange.
The SDK can only monitor a finite number of geofences simultaneously. As the
device moves, it activates the geofences closest to the current position and
deactivates those that are too far away. This event fires whenever that set
changes — reporting which geofences just became active (on) and which were
just removed from active monitoring (off).
BackgroundGeolocation.onGeofencesChange((event) => {
for (const geofence of event.on) {
console.log("[onGeofencesChange] Activated:", geofence.identifier);
}
for (const identifier of event.off) {
console.log("[onGeofencesChange] Deactivated:", identifier);
}
});
