GradientPainter class abstract

The base class for LinearGradientPainter, RadialGradientPainter, and SweepGradientPainter.

LinearGradientPainter, RadialGradientPainter, and SweepGradientPainter can be used interchangeably in BoxDecorations, or can be used to build a Shader to paint directly onto a Canvas. See: createShader.

Properties

colors List<Color>
The colors the gradient should obtain at each of the stops.
finalinherited
colorSpace ColorSpace?
The color space the colors of the gradient will be interpolated in.
no setter
density double
Defines the number of steps to generate in relation to the number of device pixels the gradient spans.
no setter
hashCode int
The hash code for this object.
no setterinherited
invert bool
If false, the colors will be interpolated in the color space defined by the starting color within any pairing, however if true, the colors will be interpolated in the space defined by the ending color.
no setter
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
stops List<double>?
A list of values from 0.0 to 1.0 that denote fractions along the gradient.
finalinherited
transform GradientTransform?
The transform, if any, to apply to the gradient.
