BlurBox class

BlurBox 是一个带有毛玻璃（高斯模糊）效果的透明背景容器部件，可自定义圆角、背景颜色、边框颜色和透明度。

典型用法：

BlurBox(
  radius: 20.0,
  color: Colors.white,
  borderColor: Colors.blue,
  opacity: 0.5,
  child: Padding(
    padding: EdgeInsets.all(16.0),
    child: Text('Blurred Area'),
  ),
)

参数说明：

  • radius: 容器的圆角半径，默认为 30.0。
  • borderWidth: 边框宽度，默认为 0.0。
  • opacity: 背景颜色透明度，取值范围 0.0 ~ 1.0，默认为0.3。

返回值： 返回一个带有毛玻璃效果和圆角、边框装饰的 Widget。
