How to write by SpWML
========================

.. code-block:: none
   
   (scroll)
   +(single child block)

----

Summary
===============

A block with a single child block.

If the size of the inner child block exceeds the size of the parent block, it will be scrollable.

Depending on the layout, views within the scrollable area may interfere with views outside of it.

In that case, add **elevation: 0.0** or similar.

This may resolve the issue because it will be internally wrapped in a Material widget.

It has a variable with parameters equivalent to Flutter `SingleChildScrollViewclass <https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html>`__ .
