ShutterCallback typedef Null safety

  1. @Reference('android_hardware/camera/ShutterCallback')
ShutterCallback = void Function()

Callback used to signal the moment of actual image capture.

Called as near as possible to the moment when a photo is captured from the sensor.

This is a good opportunity to play a shutter sound or give other feedback of camera operation. This may be some time after the photo was triggered, but some time before the actual data is available.

See: Camera.takePicture.
