LinearGradientPainter class

A 2D linear gradient.

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.

LinearGradientPainter({AlignmentGeometry begin = Alignment.centerLeft, AlignmentGeometry end = Alignment.centerRight, required List<Color> colors, List<double>? stops, TileMode tileMode = TileMode.clamp, GradientTransform? transform, ColorSpace? colorSpace, bool invert = false, double density = 0.075})
A 2D linear gradient.

Properties

begin AlignmentGeometry
The offset at which stop 0.0 of the gradient is placed.
finalinherited
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.
final
density double
Defines the number of steps to generate in relation to the number of device pixels the gradient spans.
final
end AlignmentGeometry
The offset at which stop 1.0 of the gradient is placed.
finalinherited
hashCode int
The hash code for this object.
no setteroverride
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.
final
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
tileMode TileMode
How this gradient should tile the plane beyond in the region before begin and after end.
finalinherited
transform GradientTransform?
The transform, if any, to apply to the gradient.
