flutter pub add animated根據套件公開資料產生的選型評估，僅供參考。
動畫套件是為Flutter設計的一個輕量級但功能強大的隱式動畫庫，旨在簡化平滑、宣告式動畫的建立。它提供直覺的API，用於動畫化不透明度、位置和縮放等屬性，而無需顯式管理AnimationController。非常適合尋求在多個平台使用簡潔、易讀程式碼來實現常見動畫模式的開發者。

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.
