Unstyled

We provide in-depth information on how to customize and extend the component's functionality to meet your needs. Below, we describe how to modify the component to suit your requirements.

Customizing the Fab

We have a function called createFab which can be used to create a custom fab component. This function takes in a configuration object which contains the styled components that you want to use for the fab. You can refer gluestack.io/style on how to use styled components.

Usage

Default styling of all these components can be found in the components/core/fab file. For reference, you can view the source code of the styled Fab components.
// import the styles
import { Root, Label } from "../components/core/fab/styled-components"
// import the createFab function
import { createFab } from "@gluestack-ui/fab"
// Understanding the API
const Fab = createFab({
Root,
Label,
})
// Using the fab component
export default () => (
<Fab>
<FabLabel />
<FabIcon />
</Fab>
)
