focal property

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.

Implementation

final AlignmentGeometry? focal;
