updateRenderObject method

@override void updateRenderObject(BuildContext context, covariant RenderSliverRow renderObject)

Updates the render object when the widget is rebuilt.

This method regenerates the list of sizes and marks the render object as needing layout.

Implementation

@override
void updateRenderObject(BuildContext context, RenderSliverRow renderObject) {
  renderObject
    ..sizesValue = List.generate(
      _children.length,
      (index) {
        final item = _children.elementAt(index);
        return SliverRowSize(percent: item.percent, size: item.size);
      },
    )
    ..markNeedsLayout();
}
