属性

名称	类型	默认值	说明
side	Optional[BorderSide]	None	The color and weight of the border line. If None (the default), the color and weight are resolved by the Material theme for each interactive state — for example, the focused border uses the theme's primary color. An explicit side applies to the enabled state; provide per-state borders on border for full control.
border_radius	BorderRadiusValue	4	The radii of the border's rounded rectangle corners.
gap_padding	Number	4.0	Horizontal padding on either side of the border's gap cut out for the floating label. Must be non-negative.
