setRemoteVideoRenderListener method Null safety

Future<int?> setRemoteVideoRenderListener(
  1. CustomRemoteRender param
)

开始自定义视频渲染，利用外接纹理的方式进视频渲染。

参数 见CustomRender定义

返回 textureId 纹理id

参考文档：自定义采集和渲染

调用示例

var textureId = await trtcCloud.setRemoteVideoRenderListener( CustomRemoteRender( userId: userId, streamType: TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_BIG, width: 360, height: 369));

Texture(key: valueKey, textureId: textureId)

调用时机：在onUserVideoAvailable为true的时候调用

Implementation

Future<int?> setRemoteVideoRenderListener(CustomRemoteRender param) {
  return _channel.invokeMethod('setRemoteVideoRenderListener', {
    "userId": param.userId,
    "streamType": param.streamType,
    "width": param.width,
    "height": param.height,
  });
}
