Overview
The gap package provides simple Flutter widgets to easily add consistent spacing within Flex containers like Columns, Rows, and scrolling views. It eliminates the need for manual EdgeInsets or SizedBox by offering a clean, declarative way to insert gaps between children. Ideal for improving layout readability and reducing boilerplate code in UIs with nested layouts. The package supports all major platforms and integrates seamlessly with existing Flutter projects.
