isOutbounding function

bool isOutbounding({ required double dx, required double dy, required Offset offset, required Offset scroll, required Size itemSize, required Size gridSize, })

Computing bounding

Implementation

bool isOutbounding({
  required double dx,
  required double dy,
  required Offset offset,
  required Offset scroll,
  required Size itemSize,
  required Size gridSize,
}) {
  final tx = dx + scroll.dx;
  final ty = dy + scroll.dy;
  final left = tx - offset.dx - itemSize.width / 2 - 16.0;
  final top = ty - offset.dy - itemSize.height / 2 - 16.0;

  final inx = left > -itemSize.width && left < gridSize.width;
  final iny = top > -itemSize.height && top < gridSize.height;

  return !inx || !iny;
