The Ultimate Flutter Layout Generator

Building responsive UI layouts is the foundation of front-end development. While the CSS Flexbox model has become the industry standard for aligning and distributing space among items in a container, native mobile SDKs implement these concepts using entirely different syntax and paradigms. This generator lets you build your layout visually and automatically translates your configuration into exact Flutter code.

Layout in Flutter

Flutter does not use the term "Flexbox" directly for most layouts, instead opting for the heavily-used Row and Column widgets (which actually inherit from a Flex widget under the hood). Instead of justify-content and align-items, Flutter maps these concepts to mainAxisAlignment and crossAxisAlignment. A critical difference is that Flutter Rows and Columns do not have a native gap property; spacing is traditionally achieved by inserting SizedBox widgets between children, or by using a Wrap widget if wrapping is required.
