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.
const

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.

createShader(Rect rect, {TextDirection? textDirection}) → Shader: Creates a Shader for this gradient to fill the given rect.
override
lerpFrom(Gradient? a, double t) → Gradient?: Linearly interpolates from another Gradient to this.
inherited
lerpTo(Gradient? b, double t) → Gradient?: Linearly interpolates from this to another Gradient.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
scale(double factor) → LinearGradientPainter: Returns a new LinearGradient with its colors scaled by the given factor.
override
toString() → String: A string representation of this object.
