Module padding 

Size constraint nodes.

Margin wraps a single child in a runtime-configurable margin.

Minimum wraps a single child with a configurable minimum size, allowing for the child to be precisely aligned or given a fixed size. It can also be used without a child to create an empty, fixed-size space.

Alignment caveats with Margin

When using Center on the child, the child will be aligned to the center of the space after the restriction from the margin is applied. All other alignments hug the edges, giving the correct appearances.

To avoid the alignment shift while keeping centering, have symmetrical margins or use Minimum with the intended area.

Structs

Maintains a margin around a singular child.

Minimum

Maintains an additional constraint to minimum size.
