React Native Super Grid

Responsive Grid View for React Native.

Getting Started

This library export two components - FlatGrid (similar to FlatList) and SectionGrid (similar to SectionList). Both components render a Grid layout that adapts itself to various screen resolutions.

Instead of passing an itemPerRow argument, you pass itemDimension and each item will be rendered with a dimension size equal to or more than (to fill the screen) the given dimension.

Internally, these components use the native FlatList and SectionList.

Demo Snack

Version 3.x, please refer v3 branch for documentation

Version 2.x and older, please refer v2 branch for documentation

v3 to v4 Migration

• Rename FlatList's items prop to data.
• v4 is based on React hooks, and requires React Native version > 0.59.
• Methods called on SectionList/FlatList refs can be called directly now (because of forwardRef). i.e Instead of ref.current.sectionList.scrollToLocation, use ref.current.scrollToLocation.

Installing

You can install the package via npm.

npm install react-native-super-grid

Usage (FlatGrid)

import { FlatGrid } from 'react-native-super-grid';

<FlatGrid
  itemDimension={130}
  data={[1,2,3,4,5,6]}
  renderItem={({ item }) => (<Text>{item}</Text>)}
/>

Usage (SectionGrid)

import { SectionGrid } from 'react-native-super-grid';

<SectionGrid
  itemDimension={130}
  sections={[
    {
      title: 'Numbers',
      data: [1,2,3,4,5,6],
    },
    {
      title: 'Alphabets',
      data: ['A', 'B', 'C', 'D', 'E'],
    },
  ]}
  renderItem={({ item }) => (<Text>{item}</Text>)}
  renderSectionHeader={({ section }) => (
    <Text style={{ fontSize: 20 }}>{section.title}</Text>
  )}
/>

Properties

| Property | Type | Default Value | Description | |---|---|---|---| | renderItem | Function | | Function to render each object. Should return a react native component. Same signature as that of FlatList/SectionList's renderItem (with an additional key rowIndex). | | data (for FlatGrid) sections (for SectionGrid) | Array | | Data to be rendered. renderItem will be called with each item in this array. Same signature as that of FlatList/SectionList. | | | itemDimension | Number | 120 | Minimum width or height for each item in pixels (virtual). | | fixed | Boolean | false | If true, the exact itemDimension will be used and won't be adjusted to fit the screen. | | spacing | Number | 10 | Spacing between each item. | | style | FlatList styles (Object) | | Styles for the container. Styles for an item should be applied inside renderItem. | | itemContainerStyle | styles (Object) | | Style for item's container. Not needed for most cases. | staticDimension | Number | | Specifies a static width or height for the container. If not passed, maxDimension will be used.| | maxDimension | Number | | Specifies a maximum width or height for the container. If not passed, full width/height of the screen will be used.| | horizontal | boolean | false | If true, the grid will be scrolling horizontally. If you want your item to fill the height when using a horizontal grid, you should give it a height of '100%'. This prop doesn't affect the SectionGrid, which only scrolls vertically. | | onLayout | Function | | Optional callback ran by the internal FlatList or SectionList's onLayout function, thus invoked on mount and layout changes. | | listKey | String | | A unique identifier for the Grid. This key is necessary if you are nesting multiple FlatGrid/SectionGrid inside another Grid (or any VirtualizedList).| | keyExtractor | Function | | A function (item, rowItemIndex) => {String} that should return a unique key for the item passed.|

All additional props you pass will be passed on to the internal FlatList/SectionList. This means you can make use of various props and methods like ListHeaderComponent, onEndReached, onRefresh...etc. While these are not tested for compatibility, most of them should work as expected.

In SectionGrid, section argument in methods like renderSectionHeader, renderSectionFooter, ItemSeparatorComponent will slightly different from the actual section you passed. The data key in the section will be the grouped versions of items (items that go in one row), and the original list of items can be found in originalData key. All other keys will remain intact.
