GradientTransform class abstract
Base class for transforming gradient shaders without applying the same transform to the entire canvas.
For example, a SweepGradient normally starts its gradation at 3 o'clock
and draws clockwise. To have the sweep appear to start at 6 o'clock, supply
a GradientRotation of pi/4 radians (i.e. 45 degrees).

Constructors
- GradientTransform()
-
Abstract const constructor. This constructor enables subclasses to provide
const constructors so that they can be used in const expressions.

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

toString(
) → String -
A string representation of this object.
inherited
-
transform(
Rect bounds, {TextDirection? textDirection}) → Matrix4? - When a Gradient creates its Shader, it will call this method to determine what transform to apply to the shader for the given Rect and TextDirection.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
