Constructors

ElRing({Key? key, required Widget child, Duration? duration, Curve? curve, bool show = true, double? width, double? offset, Color? color, double? strokeAlign, Border? border, BorderRadius? borderRadius, Gradient? gradient})
在小部件周围绘制轮廓环，轮廓环不会占据小部件的空间，通常情况下它用于聚焦外观，其效果类似于 CSS 中的 outline
const
