How to use the expo-location.stopGeofencingAsync function in expo-location

it('should raise an error when call function with invalid arguments', () => {
    // $ExpectError: need a string
    stopGeofencingAsync(69);
  });
});

it('should passes when used properly', () => {
    stopGeofencingAsync('taskName').then(result => {
      (result: void);

      // $ExpectError: check any
      (result: string);
    });
  });

toggleGeofencing = async () => {
    if (!this.canToggleGeofencing()) {
      return;
    }

    if (this.state.isGeofencing) {
      await Location.stopGeofencingAsync(GEOFENCING_TASK);
      this.setState({ geofencingRegions: [] });
    } else {

      alert(
        'You will be receiving notifications when the device enters or exits from selected regions.'
      );
    }
    this.setState(state => ({ isGeofencing: !state.isGeofencing }));
