createBoxPainter method

  1. @override
_BoxDecorationPainter createBoxPainter ([VoidCallback onChanged ])

Returns a BoxPainter that will paint this decoration.

The onChanged argument configures BoxPainter.onChanged. It can be omitted if there is no chance that the painter will change (for example, if it is a BoxDecoration with definitely no DecorationImage).


_BoxDecorationPainter createBoxPainter([VoidCallback onChanged]) {
  assert(onChanged != null || image == null);
  return _BoxDecorationPainter(this, onChanged);
