flutter pub add animated基于插件公开信息、社区数据与项目使用情况整理的选型参考。
动画包是为Flutter设计的一个轻量级但功能强大的隐式动画库，旨在简化流畅、声明式动画的创建。它提供了直观的API，用于动画化不透明度、位置和缩放等属性，而无需显式管理AnimationController。非常适合希望在多个平台上使用简洁、可读代码实现常见动画模式的开发者。

Animated is a very simple (yet powerful) implicit animation library made for Flutter.
Its goal is to be able to create a smooth animation between two values when an AnimatedContainer is not enough.
@override
Widget build(BuildContext context) {
return Animated(
value: 1.2,
curve: Curves.easeInOut,
duration: Duration(milliseconds: 300),
builder: (context, child, animation) => Transform.scale(
scale: animation.value,
child: child,
),
child: Container(
width: 40,
height: 40,
color: Colors.red,
),
);
}
In this example, whenever the value changes, the builder function will be called at each frame, from the old value to the new one.
Any widget that is not modified by the animation should be moved to the child property for optimization.
