SizeCalculated class

A size unit that performs calculations between two other size units.

This allows creating complex sizing expressions by combining different size units with mathematical operations. For example, you could create a size that is the sum of a fixed size and a percentage of viewport size.

The calculation is performed by first computing both operand sizes, then applying the operation to get the final result.

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 by calculating both operands and applying the operation.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toCodeString() → String

Converts the size unit to a code string representation.

override

toString() → String

A string representation of this object.

operator +(SizeUnit other) → SizeUnit

Available on SizeUnit, provided by the SizeUnitExtension extension

Adds two size units together.

operator -(SizeUnit other) → SizeUnit

Available on SizeUnit, provided by the SizeUnitExtension extension

Subtracts one size unit from another.

operator /(SizeUnit other) → SizeUnit
