After a hot reload, RenderObject does not relayout

This means if we change the axis, no new constraints are processed.

This likely will be fixed with making each property a setter and getter and making the correct thing dirty. Either paint or layout.

turns out I wasn't calling the correct setters in my _RenderTooltipOverlay

was doing

EdgeInsets get margin => _margin;
  EdgeInsets _margin;
  set margin(EdgeInsets value) {
    if (_margin == value) return;
    _margin = margin;
    markNeedsLayout();
  }

instead of

EdgeInsets get margin => _margin;
  EdgeInsets _margin;
  set margin(EdgeInsets value) {
    if (_margin == value) return;
    _margin = value;
    markNeedsLayout();
  }
