createShader function

Shader createShader({ required List<Color> colors, required double width, required double height, })

Creates a linear gradient shader.

The shader is created using the provided colors, width, and height. The gradient starts from the top left and ends at the center right.

The colors parameter is a list of colors that define the gradient. The width and height parameters define the size of the area covered by the gradient.

Returns a ui.Shader that can be used to paint a Canvas.

Implementation

ui.Shader createShader({
  required List<Color> colors,
  required double width,
  required double height,
}) {
  return LinearGradient(
    begin: FractionalOffset.topLeft,
    end: FractionalOffset.centerRight,
    colors: colors,
  ).createShader(
    Rect.fromLTWH(
      0,
      0,
      width,
      height,
    ),
  );
