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).

- BorderRadius, a variant that uses physical labels (
topLeft
andtopRight
instead oftopStart
andtopEnd
).

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
-
add(
BorderRadiusGeometry other) → BorderRadiusGeometry -
Returns the sum of two BorderRadiusGeometry objects. [...]
override
-
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
-
subtract(
BorderRadiusGeometry other) → BorderRadiusGeometry -
Returns the difference between two BorderRadiusGeometry objects. [...]
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]
inherited
-
toString(
) → String -
Returns a string representation of this object.

Operators
-
operator %(
double other) → BorderRadiusDirectional -
Computes the remainder of each corner by the given factor.
override
-
operator *(
double other) → BorderRadiusDirectional -
Scales each corner of the BorderRadiusDirectional by the given factor.
override
-
operator +(
BorderRadiusDirectional other) → BorderRadiusDirectional - Returns the sum of two BorderRadiusDirectional objects.
-
operator -(
BorderRadiusDirectional other) → BorderRadiusDirectional - Returns the difference between two BorderRadiusDirectional objects.
-
operator /(
double other) → BorderRadiusDirectional -
Divides each corner of the BorderRadiusDirectional by the given factor.
override
-
operator unary-(
) → BorderRadiusDirectional -
Returns the BorderRadiusDirectional object with each corner negated. [...]
override
-
operator ~/(
double other) → BorderRadiusDirectional -
Integer divides each corner of the BorderRadiusDirectional by the given factor.
override
-
operator ==(
dynamic other) → bool -
The equality operator. [...]
