BorderRadiusDirectional class
An immutable set of radii for each corner of a rectangle, but with the corners specified in a manner dependent on the writing direction.
This can be used to specify a corner radius on the leading or trailing edge of a box, so that it flips to the other side when the text alignment flips (e.g. being on the top right in English text but the top left in Arabic text).

Constructors
- BorderRadiusDirectional.all(Radius radius)
-
Creates a border radius where all radii are
radius
.const - BorderRadiusDirectional.circular(double radius)
- Creates a border radius where all radii are Radius.circular(radius).
- BorderRadiusDirectional.horizontal({Radius start = Radius.zero, Radius end = Radius.zero})
-
Creates a horizontally symmetrical border radius where the start and end
sides of the rectangle have the same radii.
const
- BorderRadiusDirectional.only({Radius topStart = Radius.zero, Radius topEnd = Radius.zero, Radius bottomStart = Radius.zero, Radius bottomEnd = Radius.zero})
-
Creates a border radius with only the given non-zero values. The other
corners will be right angles.
const
- BorderRadiusDirectional.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.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
resolve(
TextDirection? direction) → BorderRadius -
Convert this instance into a BorderRadius, so that the radii are
expressed for specific physical corners (top-left, top-right, etc) rather
than in a direction-dependent manner.
override
-
toString(
) → String -
A string representation of this object.
