| hey @Jaemin-VIRNECT, Tested it out this is a cool feature, but since zoom is only supported on iOS/Android, I recommend adding it to the Helper https:github.com/flutter-webrtc/flutter-webrtc/blob/main/lib/src/helper.dart class Helper { .... Future<void> setZoom({MediaStreamTrack videoTrack, double zoomLevel}) { if(WebRTC.platformIsAndroid || WebRTC.platformIsiOS) { await WebRTC.invokeMethod( 'mediaStreamTrackSetZoom', <String, dynamic>{'trackId': videoTrack.id, 'zoomLevel': zoomLevel}, ); } else { throw Exception('setZoom only support for mobile devices!'); } } ... } await Helper.setZoom(videoTrack, zoomLevel); |

| How do I use this, I am using flutter_webrtc: ^0.12.6 and webrtc_interface: ^1.2.0 but I get error that setZoom method is notdefined on videoTrack. Am I missing something? |

iOS and AOS support (tested on iOS and AOS mobile devices)
How to use?
final videoTrack = _localStream!
.getVideoTracks()
.firstWhere((track) => track.kind == 'video');
await WebRTC.invokeMethod('mediaStreamTrackSetZoom',
<String, dynamic>{'trackId': videoTrack.id, 'zoomLevel': zoomLevel});
//After this PR is published.
(webrtc_interface version needs to be updated in pubspec.yaml)
await videoTrack.setZoom(zoomLevel);
