ClipOval class Null safety

A widget that clips its child using an oval.

By default, inscribes an axis-aligned oval into its layout dimensions and prevents its child from painting outside that oval, but the size and location of the clip oval can be customized using a custom clipper.

See also:

  • CustomClipper, for information about creating custom clips.
  • ClipRect, for more efficient clips without rounded corners.
  • ClipRRect, for a clip with rounded corners.
  • ClipPath, for an arbitrarily shaped clip.
