    ・ツリー内の特定の場所にあるウィジェットのインスタンス化。
    ・ウィジェットはサブツリーを構成する方法を記述しますが、ウィジェットは不変であるため、同じウィジェットを使用して複数のサブツリーを同時に構成できます。要素は、ツリー内の特定の場所を構成するためのウィジェットの使用を表します。時間の経過とともに、特定の要素に関連付けられたウィジェットは変更される可能性があります。たとえば、親ウィジェットが再構築され、この場所に新しいウィジェットが作成された場合などです。要素はツリーを形成します。ほとんどの要素には一意の子がありますが、一部のウィジェット ( RenderObjectElementのサブクラスなど) には複数の子がある場合があります。

    ・RenderObjectWidget は、アプリケーションの実際のレンダリングを提供する RenderObject をラップする RenderObjectElement の構成を提供します。
    ・通常、RenderObjectWidget を直接サブクラス化するのではなく、レンダリング オブジェクト ウィジェットを次のいずれかにサブクラス化します。
    　・LeafRenderObjectWidget(ウィジェットに子がない場合)
    　・SingleChildRenderObjectWidget(ウィジェットに子が 1 つだけある場合)
    　・MultiChildRenderObjectWidget(ウィジェットが子のリストを受け取る場合)
    　・SlottedMultiChildRenderObjectWidget(ウィジェットがその子を別の名前付きスロットに編成する場合)
    ・サブクラスは createRenderObject と updateRenderObject を実装する必要があります。
    メソッド）
    ・createRenderObject()
    　この RenderObjectWidget で記述された構成を使用して、この RenderObjectWidget が表す RenderObject クラスのインスタンスを作成します。
    ・updateRenderObject()
    　この RenderObjectWidget によって記述された設定を指定された RenderObject にコピーします。これは、このオブジェクトの createRenderObject によって返されるものと同じタイプになります。
    ・didUnmountRenderObject()
    　指定された RenderObject は、このオブジェクトの createRenderObject によって返されるものと同じタイプになります。
