useArtboardSize property Null safety
Determines whether to use the inherent size of the artboard, i.e. the absolute size defined by the artboard, or size the widget based on the available constraints only (sized by parent).
false, i.e. defaults to sizing based on the available
constraints instead of the artboard size.
true, the artboard size is constrained by the parent constraints.
Using the artboard size has the benefit that the widget now has an
false, the intrinsic size is
(0, 0) because
there is no size intrinsically - it only comes from the parent
constraints. Consequently, if you intend to use the widget in the subtree
of an IntrinsicWidth or IntrinsicHeight widget or intend to directly
obtain the RenderBox.getMinIntrinsicWidth et al., you will want to set
final bool useArtboardSize;
