UniversalListView class

Create ListView to provide a consistent UI across web, desktop, and mobile.

The UniversalAppBar and UniversalSliverAppBar will automatically select and set whether to use the normal list or the Sliver list.

Otherwise, it can be used in the same way as a normal ListView.

When onRefresh is specified, RefreshIndicator is automatically set.

Setting showScrollbarWhenDesktopOrWeb to true will show scrollbars on desktop and web.

It is responsive and the maximum width is set by UniversalScaffold.breakpoint.

Webとデスクトップ、モバイルで一貫したUIを提供するためのListViewを作成します。

UniversalAppBar、UniversalSliverAppBarによって通常のリストかSliverのリストかを自動で選択して設定します。

その他は通常のListViewと同じように利用可能です。

onRefreshを指定するとRefreshIndicatorを自動で設定します。

showScrollbarWhenDesktopOrWebをtrueにするとデスクトップとWebでスクロールバーを表示します。

レスポンシブ対応しておりUniversalScaffold.breakpointによって最大の横幅が設定されます。
