Props

Accept all props in FlatList

Name Type Required Description
data Array ✓ Same as FlatList data.
renderItem function ✓ Simular to FlatList renderItem but this module does NOT accept JSX.Element.
isEditing boolean ✓ If isEditing is true, item can be sorted by drag & drop, but onPress/onLongPress within items would be blocked.
onOrderChanged function ✓ Callback when touch end. (orderedData: Array<T>, from: number, to: number) would be returned. orderedData is an array of data with new order. from is the original position of the dragged item. to is the new position of the dragged item.
keyExtractor function Same as FlatList keyExtractor.
numColumns number Default 1. Same as FlatList numColumns. If only 1 item is rendered in each row, you may use react-native-draggable-flatlist which has better performance.
listWidth number Default 100% of screen width. Width of the whole list, This value would be used to calcuate the width of item by listWidth / numColumns.
itemHeight number Default listWidth / numColumns. Height of items.
animMoveDuration number Default 1000. The time taken (miliseconds) for non-dragged items to animate.
debounce number Default undefined. Debounce (miliseconds) of non-dragged items to start animation. If value is undefined, there would be no debounce. Implementing debounce can improve performance. If debounce is needed, value 300 is recommanded.
