ColorGradient class abstract

An abstract base class representing a color gradient with multiple color stops.

ColorGradient provides a common interface for working with gradients that can have colors added, modified, or removed at specific positions. This is useful for creating custom gradient pickers and editors.

Implementations should handle the gradient type (linear, radial, sweep, etc.) and provide methods to manipulate color stops and their positions.

• LinearColorGradient
• RadialColorGradient
• SweepColorGradient

Methods

changeColorAndPositionAt(int index, ColorDerivative color, double position) → ColorGradient

Changes both the color and position at the specified index.

changeColorAt(int index, ColorDerivative color) → ColorGradient

Changes the color at the specified index.

changePositionAt(int index, double position) → ColorGradient

Changes the position of the color stop at the specified index.

copyWith() → ColorGradient

Creates a copy of this gradient with optional modifications.

insertColorAt(ColorDerivative color, Offset position, Size size, TextDirection textDirection) → ({ColorGradient gradient, int index})

Inserts a new color stop at a specific position in the gradient.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toGradient() → Gradient

Converts this color gradient to a Flutter Gradient.

toString() → String

A string representation of this object.
