Flutter阴影裁剪插件proste_shadow_clip的使用

proste_shadow_clip

用于裁剪并绘制阴影的部件，并且阴影会跟随裁剪路径。

使用方法

你可以使用 proste_bezier_curve 或者 flutter_custom_clippers 来创建裁剪器。

参数列表

示例代码

Center(
  child: ProsteShadowClip(
    child: Container(
      width: 300,
      height: 100,
      color: Colors.pink,
    ),
    shadow: [
      BoxShadow(
        blurRadius: 5,
        spreadRadius: 2,
      ),
    ],
    clipper: MultipleRoundedCurveClipper(), // 创建一个自定义裁剪器
  ),
);

      [DeviceOrientation.portraitUp, DeviceOrientation.portraitDown]);
  SystemUiOverlayStyle style = SystemUiOverlayStyle(
    statusBarColor: Colors.transparent,
  );
  SystemChrome.setSystemUIOverlayStyle(style);
}
