StreamSpacing class

Spacing primitives for the Stream design system.

Provides consistent spacing values for padding, margins, and gaps between UI elements. Spacing values are the same across all platforms.

{@tool snippet}

To use spacing values:

const spacing = StreamSpacing();
Container(
  padding: EdgeInsets.all(spacing.md),
  child: Column(
    spacing: spacing.xs,
    children: [...],
  ),
);

{@end-tool}
