GradientTransform class Null safety
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).

-
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. [...]
