Controls how one widget replaces another widget in the tree.

final, inherited

random → Random

随机动画时使用构建随机数

final

final

Methods

build(BuildContext context) → Widget

lib/demo/shake/shake_animation_builder.dart

override

buildMatrix4() → Matrix4

lib/demo/shake/shake_animation_builder.dart 根据不同的模式来构建不同的矩阵变化

buildRandowMatrix4() → Matrix4

lib/demo/shake/shake_animation_builder.dart 构建随机变换的矩阵 animation.value同时要适配旋转， Matrix4的旋转是使用弧度计算的，一般抖动使用 0.1左右的弧度微旋转即可 所以这时配置的animation.value的取值范围建议使用 -0.1,0.1 那么对于Matrix4的translationValues平移来讲是使用的逻辑像素 -0.1,0.1这个范围的变动对于平移无法有明显的抖动效果 所以在这里 对于平移来说使用的 -1.5,1.5 就会有明显一点的抖动效果 random.nextDouble()这个方法的值范围为 0.0-1.0 然后通过结合配置的randomValue抖动的波动范围 默认为 5 Matrix4平移范围为 -1.5,6.5

createElement() → StatelessElement

Creates a StatelessElement to manage this widget's location in the tree.
