@appandflow/masonry-list

Allows creating masonry style list layouts in a performant way.

This component leverages FlatList to render performant masonry layout lists. The main caveat right now is that it doesn't support measuring cells (yet) so you need to be able to provide the dimensions.

Start

forked from AppAndFlow/react-native-masonry-list(https://github.com/AppAndFlow/react-native-masonry-list)

Installation

yarn add js-masonry-list

Usage

import MasonryList from 'js-masonry-list';

Props

This component supports most of the props of FlatList plus a few extras one:

getHeightForItem: ({ item: any, index: number }) => number,

Returns the height for a specific item. Note that this it not optional for now.

numColumns: number

The number of columns.

itemOffsetHeight: number

The number of itemOffsetHeight。You must ensure that itemHeight is the outermost container, for example, item has marginTop

renderItem: ({ item: any, index: number, column: number, columnIndex: number }) => ?ReactElement<*>,

Same as renderItem from FlatList but also gets passed the column index. notice(columnIndex is index at old list)

ListFooterComponent: ReactElement<*>

Same as ListFooterComponent from FlatList.

refreshConfig: Object

Same as refreshConfig from RefreshControl config.

Example

TODO

-[x] Support measuring items automatically and get rid of getHeightForItem.

-[x] Implement onEndReached in a way that it isn't called multiple times.

-[x] Support FooterComponent.

-[] Long term, could probably be implemented without using multiple VirtualizedList to make it more performant and less hacky.
