getExposureOffsetStepSize method
Gets the supported step size for exposure offset for the selected camera in EV units.
Returns 0 when the camera supports using a free value without stepping.
Implementation
@override
Future<double> getExposureOffsetStepSize(int cameraId) async {
final double? stepSize = await _channel.invokeMethod<double>(
'getExposureOffsetStepSize',
<String, dynamic>{'cameraId': cameraId},
);
return stepSize!;
}
