setCameraZoomRatio method

Future<int?> setCameraZoomRatio(
  1. double value
)

Set the zoom factor (focal length) of camera (supports only the Android and iOS platforms)

The value range is 1–5. 1 indicates the furthest view (normal lens), and 5 indicates the nearest view (enlarging lens). We recommend you set the maximum value to 5. If the maximum value is greater than 5, the video will become blurry.

Parameters:

value Value range: 1–5. The greater the value, the further the focal length

Return: 0: success; negative number: failure

Implementation

Future<int?> setCameraZoomRatio(double value) async {
  var result = await _channel.invokeMethod('setCameraZoomRatio', {
    "value": value.toString(),
  });
  return V2TXLiveFlutterResult.intValue(result);
}
