Interface Subscription

Example

// Event-listeners return a Subscription instance, containing a .remove() method.
const subscription = BackgroundGeolocation.onLocation(location => {
  console.log("[onLocation] ", location);
});
.
.
.
// Later, to remove the event-listener:
subscription.remove();
Copy

One might typically manage a collection of Subscription instances

Example

import BackgroundGeolocation, {
  Location,
  Subscription
} from ...

// Your custom Collection of Subscription instances.
const SUBSCRIPTIONS = [];

// Your custom method to push a Subscription instance.
const subscribe = (subscription:Subscription) => {
  SUBSCRIPTIONS.push(subscription);
}

// Your custom method to interate your SUBSCRIPTIONS and .remove each.
const unsubscribe = () => {
  SUBSCRIPTIONS.forEach((subscription:Subscription) => subscription.remove());
}

const initBackgroundGeolocation = () {
  // Create event-listeners as usual, feeding the returned Subscription into
  // your custom  subscribe() method.
  subscribe(BackgroundGeolocation.onLocation((location:Location) => {
    console.log('[onLocation]', location);
  });

  subscribe(BackgroundGeolocation.onMotionChange((location:Location) => {
    console.log('[onMotionChange]', location);
  });

  subscribe(BackgroundGeolocation.onEnabledChange((enabled:boolean) => {
    console.log('[onEnabledChange]', enabled);
  });
}

const onDestroyView = () => {
  // Call your custom unsubscribe method
  unsubscribe();
}
