RadialGradient constructor Null safety
- {AlignmentGeometry center = Alignment.center,
- double radius = 0.5,
- required List<
Color> colors, - List<
double> ? stops, - TileMode tileMode = TileMode.clamp,
- AlignmentGeometry? focal,
- double focalRadius = 0.0,
- GradientTransform? transform}
Creates a radial gradient.
The colors argument must not be null. If stops is non-null, it must have the same length as colors.
