對話框，一般是應用的一些信息固然咱們通常都是須要自定義的，不用flutter自帶的

動畫icons

自帶的就下面14中動畫圖片，也就是從一種狀態變換成另一種狀態 好比 AnimatedIcons.close_menu,這個表示從close(X)的樣式變成menu(三)的樣式

var icons = [
      AnimatedIcons.add_event,
      AnimatedIcons.arrow_menu,
      AnimatedIcons.close_menu,
      AnimatedIcons.ellipsis_search,
      AnimatedIcons.event_add,
      AnimatedIcons.home_menu,
      AnimatedIcons.list_view,
      AnimatedIcons.menu_arrow,
      AnimatedIcons.menu_close,
      AnimatedIcons.menu_home,
      AnimatedIcons.pause_play,
      AnimatedIcons.play_pause,
      AnimatedIcons.search_ellipsis,
      AnimatedIcons.view_list
    ];

具體使用方法

animationController = AnimationController(
      vsync: this,
      duration: Duration(microseconds: 2000),
    );

    animationController.forward(); //加上這個，動畫才能執行，能夠放到按鈕的點擊事件裏面去，
...
 AnimatedIcon(
                      size: 30,
                      icon: icons[i],
                      progress: animationController,
                      semanticLabel: 'Show menu',
                    ),
