Methods

clamp({SpacingUnit min = const _FixedSpacing(0), SpacingUnit max = const _FixedSpacing(double.infinity)}) → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

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

computeSpacing({required ParentLayout parent, required LayoutAxis axis, required double viewportSize}) → double

Computes the actual spacing value.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toCodeString() → String

toString() → String

A string representation of this object.

Operators

operator *(Object other) → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

Multiplies two spacing units.

operator +(SpacingUnit other) → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

Adds two spacing units together.

operator -(SpacingUnit other) → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

Subtracts one spacing unit from another.

operator /(SpacingUnit other) → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

Divides one spacing unit by another.

operator ==(Object other) → bool

The equality operator.

inherited

operator unary-() → SpacingUnit

Available on SpacingUnit, provided by the SpacingUnitExtension extension

Negates this spacing unit (equivalent to 0 - this).

Static Methods

lerp(SpacingUnit a, SpacingUnit b, double t) → SpacingUnit

Linearly interpolates between two spacing units.

Constants

viewportSize → const SpacingUnit

Spacing equal to the viewport size along the axis.

zero → const SpacingUnit

Zero spacing.
