SizeConstraint class

A size unit that constrains another size unit between minimum and maximum bounds.

This size unit evaluates a base size and then clamps the result to be within specified min and max bounds. This is useful for ensuring sizes stay within valid ranges or creating bounded sizing behaviors.

Methods

clamp({SizeUnit min = const SizeFixed(0), SizeUnit max = const SizeFixed(double.infinity)}) → SizeUnit

Available on SizeUnit, provided by the SizeUnitExtension extension

Constrains this size unit within the specified min and max bounds.

computeSize({required ParentLayout parent, required ChildLayout child, required LayoutHandle<Layout> layoutHandle, required LayoutAxis axis, required LayoutSize contentSize, required LayoutSize viewportSize}) → double

Computes the size and clamps it between min and max bounds.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toCodeString() → String
