getInnerPath method

@override Path getInnerPath(Rect rect, { TextDirection? textDirection, })

Create a Path that describes the inner edge of the border.

This path must not cross the path given by getOuterPath for the same Rect.

To obtain a Path that describes the area of the border itself, set the Path.fillType of the returned object to PathFillType.evenOdd, and add to this object the path returned from getOuterPath (using Path.addPath).

The textDirection argument must be provided and non-null if the border has a text direction dependency (for example if it is expressed in terms of "start" and "end" instead of "left" and "right"). It may be null if the border will not need the text direction to paint itself.

See also:

• getOuterPath, which creates the path for the outer edge.
• Path.contains, which can tell if an Offset is within a Path.

Implementation

@override
Path getInnerPath(Rect rect, {TextDirection? textDirection}) {
  return Path()
    ..addRRect(borderRadius!
        .resolve(textDirection)
        .toRRect(rect)
        .deflate(borderSide.width));
}
