Instead of setting a color or font size separately on every screen, your theme lets you define it once and reuse it everywhere. Change it later, and everything using it updates together.
Steps
1. Open Global Settings
In the right sidebar, switch to the Global Settings tab.
2. Explore the six groups
Your theme is organized into six groups: Colors, Typography, Spacing, Dimensions, Borders, and Shadows. Each holds a list of reusable values for that category.
3. Add a value
Within any group, add a new entry with a short internal name, a friendlier display name (this is what you’ll see when picking it elsewhere in the editor), and the actual value – a color, a font size, whatever the group calls for.
4. Apply it to a component
When you’re setting a property on any component – a background color, a font size – look for the option to pick from your theme instead of entering a one-off value. Select the entry you created, and that component now follows your theme.
5. Update it once, everywhere
Change a theme value later, and every component using it updates automatically – no need to find and edit each one individually.
6. Set your status bar and navigation bar
The same Global Settings tab also holds your device status bar and navigation bar appearance – choose whether each follows the system default or uses a custom color.
