ShaderMask constructor Null safety
- {Key? key,
- required ShaderCallback shaderCallback,
- BlendMode blendMode = BlendMode.modulate,
- Widget? child}
Creates a widget that applies a mask generated by a Shader to its child.
The shaderCallback and blendMode arguments must not be null.
Implementation
const ShaderMask({
super.key,
required this.shaderCallback,
this.blendMode = BlendMode.modulate,
super.child,
}) : assert(shaderCallback != null),
assert(blendMode != null);
