LayoutConstraints class
Defines the size constraints for layout calculations.
LayoutConstraints specify the minimum and maximum allowable dimensions for an element during layout. The layout algorithm must respect these constraints when determining final sizes.
Constructors
- LayoutConstraints({double minWidth = 0.0, double maxWidth = double.infinity, double minHeight = 0.0, double maxHeight = double.infinity})
-
Creates constraints with the specified bounds.
const
- LayoutConstraints.tight(LayoutSize size)
- Creates tight constraints that exactly match the given size.
- LayoutConstraints.tightFor({double? width, double? height})
-
Creates tight constraints for a specific width and/or height.
