borderRadius static method

List<Map<String, dynamic>?>? borderRadius(BorderRadiusGeometry? borderRadiusGeometry)

Returns a BorderRadiusDirectional from the specified list.

The list is a list of values as interpreted by radius. An empty or missing list results in a null return value. The list should have one through four items. Extra items are ignored.

The values are interpreted as follows:

• topStart: first value.
• topEnd: second value, defaulting to same as topStart.
• bottomStart: third value, defaulting to same as topStart.
• bottomEnd: fourth value, defaulting to same as topEnd.

Implementation

static List<Map<String, dynamic>?>? borderRadius(
    BorderRadiusGeometry? borderRadiusGeometry) {
  if (borderRadiusGeometry == null) {
    return null;
  }

  final borderRadius = borderRadiusGeometry as BorderRadius;
  return [
    radius(borderRadius.topLeft),
    radius(borderRadius.topRight),
    radius(borderRadius.bottomLeft),
    radius(borderRadius.bottomRight),
  ];
}
