ResponsiveSpacer class

A flexible spacer that automatically creates a SizedBox with width or height based on its parent axis (Row/Column).

Walks the ancestor element tree to find the nearest Flex widget (Row, Column, or direct Flex) and checks its direction, then creates either a SizedBox(width:) or SizedBox(height:).

Defaults to vertical spacing if no Flex ancestor is found.

Column(children: [
  Text('Item 1'),
  const ResponsiveSpacer(),        // 16px vertical (auto-detected)
  Text('Item 2'),
  const ResponsiveSpacer(size: 24), // 24px vertical
])

Row(children: [
  Icon(Icons.star),
  const ResponsiveSpacer(),        // 16px horizontal (auto-detected)
  Text('Rating'),
])
