FAB Customization

The CustomButton.Floating component is designed to hover above your content. To ensure it stays fixed while scrolling, place it outside your ScrollView or FlatList.

| Prop | Type | Default | Description | |------|------|---------|-------------| | floatingPosition | 'bottom-right' \| 'bottom-left' \| 'top-right' \| 'top-left' | 'bottom-right' | Corner to anchor the button. | | offset | { x: number, y: number } | { x: 20, y: 20 } | Distance from the edge. | | label | string | - | If provided, creates an "Extended FAB" with text. | | style | ViewStyle | - | Override dimensions, colors, or shadows. |

Note: For the FAB to float correctly over scrollable content, ensure its parent container has flex: 1 relative to the screen, and the FAB is a sibling to the ScrollView, not a child.

Props

| Prop | Type | Default | Description | |------|------|---------|-------------| | title | string | - | The text to display. | | variant | 'primary' \| 'secondary' \| 'tertiary' \| 'elevated' \| 'outlined' \| 'text' | 'primary' | The visual style variants. | | size | 'small' \| 'medium' \| 'large' | 'medium' | Predefined sizes. | | loading | boolean | false | Shows a loading spinner. | | disabled | boolean | false | Disables interaction and modifies styles. | | gradientColors | string[] | - | Array of colors for background gradient. | | leftIcon | ReactNode | - | Element to render on the left. | | rightIcon | ReactNode | - | Element to render on the right. | | theme | ButtonTheme | - | Override default theme tokens. | | ...and standard Pressable props. |
