Constructors

View({Key? key, required List<Widget> children, Widget safeAreaCallback(Widget widget)?, Widget wrapperCallback(List<Widget> listWidget)?, Widget widgetCallback(Widget widget)?, bool? appBarDisable, Color? backgroundColor})

引数のウィジェットリスト（children）を元にスキャフォールドウィジェットを返す safeAreaCallback引数を利用することでオーバーフロー用のラッパー処理が可能 wrapperCallback引数を利用することでウィジェットリストのラッパー処理が可能 widgetCallback引数を利用することで個別のラッパー処理が可能 ※Desktop/Webアプリケーションで水平方向の(マウスドラッグによる)スクロールを有効にするため、 MaterialScrollBehaviorのオーバーライドし、MaterialAppのscrollBehaviorへ設定する必要有り
