Constructors

BorderRadius.all(Radius radius)
Creates a border radius where all radii are radius.
const
BorderRadius.circular(double radius)
Creates a border radius where all radii are Radius.circular(radius).
BorderRadius.horizontal({Radius left: Radius.zero, Radius right: Radius.zero })
Creates a horizontally symmetrical border radius where the left and right sides of the rectangle have the same radii.
const
BorderRadius.only({Radius topLeft: Radius.zero, Radius topRight: Radius.zero, Radius bottomRight: Radius.zero, Radius bottomLeft: Radius.zero })
Creates a border radius with only the given non-zero values. The other corners will be right angles.
const
BorderRadius.vertical({Radius top: Radius.zero, Radius bottom: Radius.zero })
Creates a vertically symmetric border radius where the top and bottom sides of the rectangle have the same radii.
