paints method
Retrieve all Paint objects from the paint cache for the provided
element and position. Note: Finder pattern elements can only have a max
one Paint object per position. As such they will always return a List
with a fixed size of 1
.
Implementation
List<Paint?> paints(
QRCodeElement element, {
FinderPatternPosition? position,
}) {
return element == QRCodeElement.codePixel
? _pixelPaints
: <Paint?>[_keyedPaints[_cacheKey(element, position: position)]];
}
