shaderCallback property
Called to get the gradient color for the bar pointer.
Defaults to null.
This snippet shows how to use a shaderCallback to get the colors for bar pointer.
LinearBarPointer(
shaderCallback: (Rect bounds) {
return LinearGradient(colors: [
Color(0xffE8DA5D),
Color(0xffFB7D55),
], stops: <double>[
0.4,
0.9
]).createShader(bounds);
)
Implementation
final ShaderCallback? shaderCallback;
