      keyExtractor={({ id }) => `${id}`}
      onOrderChanged={orderedData => {

      }}
      renderItem={({ item }) => {

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.
