How it is made

Description

Current MasonryList extends ScrollView and can pass down its props. Indeed, this looks similar to FlatList to provide good developer experience. Look how this is used and compare to the FlatList.

The FlatList won't offer you to draw MansonryList because when you provide numColumns bigger than 1, the native view will switch to FlatList to GridView which will render its children with identical height only.

Our MasonryList view component is able to render all child views with all different sizes.

Props

keyPrefix?: string;
loading?: boolean;
refreshing?: RefreshControlProps['refreshing'];
onRefresh?: RefreshControlProps['onRefresh'];
onEndReached?: () => void;
onEndReachedThreshold?: number;
style?: StyleProp<ScrollViewProps>;
data: T[];
renderItem: ({item: T, i: number}) => ReactElement;
LoadingView?: React.ComponentType<any> | React.ReactElement | null;
ListHeaderComponent?: React.ComponentType<any> | React.ReactElement | null;
ListEmptyComponent?: React.ComponentType<any> | React.ReactElement | null;
ListFooterComponent?: React.ComponentType<any> | React.ReactElement | null;
numColumns?: number;

keyPrefix - Add prefix for keying child views. This is currently incremented by 1.
