一统天下 flutter - widget 按钮类: Ink/InkWell/InkResponse - 让任意组件支持点击事件和点击效果
示例如下:
lib\widget\button\ink.dart
/*
* Ink/InkWell/InkResponse - 让任意组件支持点击事件和点击效果
*
* InkWell/InkResponse 用于让任意组件支持点击事件和点击效果
* InkWell 通过继承 InkResponse 的方式实现了对 InkResponse 的二次封装,从而简化了一些设置
* Ink 用于在 InkWell/InkResponse 外包装一层,从而定义 InkWell/InkResponse 在普通状态时的样式
*
* 注:如果不需要点击效果,那么用 GestureDetector 即可,参见 /input/gesture_detector.dart
