Spacer

Spacer is an empty layout component used to push siblings apart.

Row {
  Text("Document"),
  Spacer(),
  Button("Save"),
}.With(CrossAlign(CrossAxisAlignment::Center))

In a Row, it consumes available horizontal space; in a Column, it consumes available vertical space. Use Grow(factor) on ordinary content when the flexible region itself should render or participate in semantics.

Spacer has no content, events, or accessibility semantics.

API

  • Constructor: Spacer().
  • Common modifiers: Frame for a fixed minimum gap and Grow for explicit proportional behavior.

See Row and Column for flexible-axis behavior and alignment rules.
