EdgeSpacing class

Defines spacing values for all four edges of a rectangle.

This class represents absolute spacing from each edge (left, top, right, bottom). The spacing values are resolved to actual pixel values during layout.

Use this for spacing that doesn't depend on text direction, or when you need explicit control over left/right spacing (like padding or margins).

Constructors

EdgeSpacing.all(SpacingUnit value)
Creates an EdgeSpacing with the same value for all edges.
const
EdgeSpacing.only({SpacingUnit left = SpacingUnit.zero, SpacingUnit right = SpacingUnit.zero, SpacingUnit top = SpacingUnit.zero, SpacingUnit bottom = SpacingUnit.zero})
Creates an EdgeSpacing with individual edge values.
const
EdgeSpacing.symmetric({SpacingUnit horizontal = SpacingUnit.zero, SpacingUnit vertical = SpacingUnit.zero})
Creates an EdgeSpacing with symmetric horizontal and vertical values.
