startSmoothZoom method

Future<void> startSmoothZoom(
  1. int value
)

Zooms to the requested value smoothly.

The driver will notify OnZoomChangeListener of the zoom value and whether zoom is stopped at the time. For example, suppose the current zoom is 0 and startSmoothZoom is called with value 3. The OnZoomChangeListener method will be called three times with zoom values 1, 2, and 3. Applications can call stopSmoothZoom to stop the zoom earlier. Applications should not call startSmoothZoom again or change the zoom value before zoom stops. If the supplied zoom value equals to the current zoom value, no zoom callback will be generated. This method is supported if CameraParameters.isSmoothZoomSupported returns true.

value: The valid range is 0 to CameraParameters.getMaxZoom.

Throws PlatformException if the zoom value is invalid.

Implementation

  return _channel.$startSmoothZoom(this, value);
