UniversalContainer class

Create a container that is responsive.

It is recommended to place it directly under UniversalScaffold.body. Otherwise, Container is fine.

The maximum width is automatically set according to UniversalScaffold.breakpoint.

レスポンシブに対応したコンテナを作成します。

UniversalScaffold.bodyの直下に置くことをおすすめします。 それ以外はContainerで問題ございません。

UniversalScaffold.breakpointに応じて最大の横幅が自動で設定されます。
