MainActivity.java
. Be sure to follow all Android instructions!npm
or yarn
with npm
:
npm install --save react-native-draggable-flatlist
with yarn

yarn add react-native-draggable-flatlist
import DraggableFlatList from 'react-native-draggable-flatlist'
All props are spread onto underlying FlatList
Name | Type | Description |
---|---|---|
data | T[] | Items to be rendered. |
horizontal | boolean | Orientation of list. |
renderItem | (params: { item: T, index: number, drag: () => void, isActive: boolean}) => JSX.Element | Call drag when the row should become active (i.e. in an onLongPress or onPressIn ). |
renderPlaceholder | (params: { item: T, index: number }) => React.ReactNode | Component to be rendered underneath the hovering component |
keyExtractor | (item: T, index: number) => string | Unique key for each item |
onDragBegin | (index: number) => void | Called when row becomes active. |
onRelease | (index: number) => void | Called when active row touch ends. |
onDragEnd | (params: { data: T[], from: number, to: number }) => void | Called after animation has completed. Returns updated ordering of data |
autoscrollThreshold | number | Distance from edge of container where list begins to autoscroll when dragging. |
autoscrollSpeed | number | Determines how fast the list autoscrolls. |
onRef | (ref: React.RefObject<DraggableFlatList<T>>) => void | Returns underlying Animated FlatList ref. |
animationConfig | Partial<Animated.SpringConfig> | Configure list animations. See reanimated spring config |
activationDistance | number | Distance a finger must travel before the gesture handler activates. Useful when using a draggable list within a TabNavigator so that the list does not capture navigator gestures. |
layoutInvalidationKey | string | Changing this value forces a remeasure of all item layouts. Useful if item size/ordering updates after initial mount. |
onScrollOffsetChange | (offset: number) => void | Called with scroll offset. Stand-in for onScroll . |
onPlaceholderIndexChange | (index: number) => void | Called when the index of the placeholder changes |
dragItemOverflow | boolean | If true, dragged item follows finger beyond list boundary. |
dragHitSlop | object: {top: number, left: number, bottom: number, right: number} | Enables control over what part of the connected view area can be used to begin recognizing the gesture. Numbers need to be non-positive (only possible to reduce responsive area). |
debug | boolean | Enables debug logging and animation debugger. |
