TxShimmer class
小部件树上呈现微光效果的组件。 child 定义了闪光效果混合的区域。 您可以从您喜欢的任何 Widget 构建 child， 但为了获得准确的预期效果并获得更好的渲染性能，请注意一些注意事项： 使用静态 Widget（它是 StatelessWidget 的一个实例）。 Widget 应该是纯色元素。您在这些 Widget 上设置的每种颜色都将被
gradient 的颜色覆盖。微光效果只影响 child 的不透明区域，透明区域仍然保持透明。
period 控制微光效果的速度。默认值为 1500 毫秒。
direction 控制微光效果的方向。默认值为 ShimmerDirection.ltr。
gradient 控制微光效果的颜色。
loop 动画循环次数，设置为 0 使动画永远运行。
enabled 控制是否激活微光效果。设置为 false 时动画暂停
专业提示：child 应由基本简单的 Widget 组成， 例如 Container、Row 和 Column，以避免副作用。

创建一个TxShimmer
const
- TxShimmer.fromColors({required Widget child, required Color baseColor, required Color highlightColor, Key? key, Duration period = const Duration(milliseconds: 1500), ShimmerDirection direction = ShimmerDirection.ltr, int loop = 0, bool enabled = true})
-
一个方便的构造函数提供了一种简单方便的方法来创建一个 TxShimmer，
其中 gradient 是由
baseColor和highlightColor组成的 LinearGradient。
