# 隐式动画
> 在 Flutter 中寻找有关使用隐式动画的更多信息。
With Flutter's [animation library][],
you can add motion and create visual effects
for the widgets in your UI.
One part of the library is an assortment of widgets
that manage animations for you.
These widgets are collectively referred to as _implicit animations_,
or _implicitly animated widgets_, deriving their name from the
[`ImplicitlyAnimatedWidget`][] class that they implement.
The following set of resources provide many ways to learn
about implicit animations in Flutter.
通过 Flutter 的 [动画库][animation library]，
你可以为 UI 中的 widgets 添加动作并创造视觉效果。
有些库包含各种各样可以帮你管理动画的 widget。
这些 widgets 被统称为 **隐式动画** 或 **隐式动画 widget**，
其名字来源于它们所实现的 [`ImplicitlyAnimatedWidget`][] 类。
下列资源提供了许多在 Flutter 中学习使用隐式动画的方法。
