paint abstract method
- Canvas canvas,
- Rect rect, {
- TextDirection? textDirection,
- BoxShape shape = BoxShape.rectangle,
- BorderRadius? borderRadius,
override
Paints the border within the given Rect on the given Canvas.
This is an extension of the ShapeBorder.paint method. It allows
BoxBorder borders to be applied to different BoxShapes and with
different borderRadius
parameters, without changing the BoxBorder
object itself.
The shape
argument specifies the BoxShape to draw the border on.
If the shape
is specifies a rectangular box shape
(BoxShape.rectangle), then the borderRadius
argument describes the
corners of the rectangle.
The getInnerPath and getOuterPath methods do not know about the
shape
and borderRadius
arguments.
See also:
- paintBorder, which is used if the border has non-uniform colors or styles and no borderRadius.
- Border.paint, similar to this method, includes additional comments and provides more details on each parameter than described here.
Implementation
