build method

@override Widget build(BuildContext context)

此处是为了创建一个对应的平台View

Implementation

@override
Widget build(BuildContext context) {
  if (channelType == BRTCCloudConfig.BRTC_VideoView_Texture) {
    if (textureId != null) {
      return Texture(textureId: textureId!);
    }
    return Container();
  }
  if (Platform.isAndroid) {
    return AndroidView(
      viewType: channelType.toString(),
      onPlatformViewCreated: _onPlatformViewCreated,
      gestureRecognizers: widget.gestureRecognizers,
      creationParams: <String, dynamic>{
        "x": videoParam!.x,
        "y": videoParam!.y,
        "width": videoParam!.width,
        "height": videoParam!.height
      },
      creationParamsCodec: const StandardMessageCodec(),
    );
  } else if (Platform.isIOS) {
    widget.uiKitView = UiKitView(
      viewType: channelType.toString(),
      onPlatformViewCreated: _onPlatformViewCreated,
      gestureRecognizers: widget.gestureRecognizers,

        "height": videoParam!.height
      },
      creationParamsCodec: const StandardMessageCodec(),
    );
    return widget.uiKitView!;
  } else {

      child: Text(
