tileMode property
final
How this gradient should tile the plane in the region before startAngle and after endAngle.
The gradient will be painted in the sector between startAngle and endAngle. The tileMode determines what happens in the remaining area:
- TileMode.clamp: The edge colors are extended to fill the remaining area.
- TileMode.repeated: The gradient is repeated in the angular direction.
- TileMode.mirror: The gradient is mirrored in the angular direction.
- TileMode.decal: Only the gradient is drawn, leaving the remaining area transparent.
