动画icons
自带的就下面14中动画图片，也就是从一种状态变换成另外一种状态
比如 AnimatedIcons.close_menu,这个表示从close(X)的样式变成menu(三)的样式
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
];
具体使用方法
animationController = AnimationController(
vsync: this,
duration: Duration(microseconds: 2000),
);
animationController.forward(); //加上这个，动画才能执行，可以放到按钮的点击事件里面去，
...
AnimatedIcon(
size: 30,
icon: icons[i],
progress: animationController,
semanticLabel: 'Show menu',
),
