Galio is a UI toolkit and component framework for React Native that provides a consistent set of ready-made, themeable building blocks (buttons, cards, text, inputs, nav bars, etc.) so you can prototype and ship mobile UIs faster. The galio repository includes the core components and a lightweight theme system in src/theme (see colors.tsx, sizes.tsx, index.tsx) plus components under src/ such as Block, Button, Text, Input, Card, Avatar, NavBar and more.
