ScrollBuilder class

This widget can be placed on top of a ListView or SingleChildScrollView to easily add a RefreshIndicator or Scrollbar.

If showScrollbarWhenDesktopOrWeb is true, a mouse scrollable scrollbar will be displayed only on PC or Web.

If onRefresh is not null, a RefreshIndicator will be placed and Pull to Refresh will be enabled.

An internal ScrollController is created and passed to builder. If you want to specify your own ScrollController, pass it to controller.

ListViewやSingleChildScrollViewの上に配置することで、RefreshIndicatorやScrollbarを簡単に追加できるようにするためのウィジェットです。

showScrollbarWhenDesktopOrWebをtrueにすると、PCやWebでのみマウスでドラッグ可能なスクロールバーを表示します。

onRefreshがnullでない場合、RefreshIndicatorを配置し、Pull to Refreshを有効にします。

内部でScrollControllerが作られ、それがbuilderに渡されます。自身でScrollControllerを指定したい場合はcontrollerに渡してください。
