resource property

@override dynamic resource

The resource data.

Implementation

@override

  var resource = super.resource;
  final sizeInBytes = _vertices.lengthInBytes + _indices.lengthInBytes;
  if (resource?.sizeInBytes != sizeInBytes) {
    // Store the device buffer in the resource parent.
    resource = super.resource = gpu.gpuContext.createDeviceBuffer(
      gpu.StorageMode.hostVisible,
      sizeInBytes,
    );

    resource

        destinationOffsetInBytes: _vertices.lengthInBytes,
      );
  }
  return resource;

@protected void resource=(dynamic resource)

Implementation
