focal property Null safety

AlignmentGeometry? focal
final

The focal point of the gradient. If specified, the gradient will appear to be focused along the vector from center to focal.

See center for a description of how the coordinates are mapped.

If this value is specified and focalRadius > 0.0, care should be taken to ensure that either this value or center will not both resolve to Offset.zero, which would fail to create a valid gradient.
