React Native Super Grid

Responsive Grid View for React Native.

Getting Started

This library export two components - FlatGrid (similar to FlatList) and SectionGrid (similart to SecionList). 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.

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

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}
  items={[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: 'Albhabets',
      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).
items (for FlatGrid) sections (for SectionGrid)	Array		Items 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	undefined	Specifies a static 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	undefined	A unique identifier for the Grid. This key is necessary if you are nesting multiple FlatGrid/SectionGrid inside another Grid (or any VirtualizedList).

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.

v2 to v3 Migration

The major API change in v3 was renaming the components to FlatGrid and SectionGrid and making the renderItem signature to match with FlatList and SectionList.

So instead of

import GridView from 'react-native-super-grid';
import { SuperGridSectionList } from 'react-native-super-grid';

use

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

Also change the renderItem function parameters from

<GridView
  items={[1,2,3,4,5,6]}
  renderItem={(item, index) => (<Text>{item}</Text>)}
/>

to

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

FlatGrid Example

import { StyleSheet, View, Text } from 'react-native';
import { FlatGrid } from 'react-native-super-grid';

export default class Example extends Component {
  render() {
    const items = [
      { name: 'TURQUOISE', code: '#1abc9c' }, { name: 'EMERALD', code: '#2ecc71' },
      { name: 'PETER RIVER', code: '#3498db' }, { name: 'AMETHYST', code: '#9b59b6' },
      { name: 'WET ASPHALT', code: '#34495e' }, { name: 'GREEN SEA', code: '#16a085' },
      { name: 'NEPHRITIS', code: '#27ae60' }, { name: 'BELIZE HOLE', code: '#2980b9' },
      { name: 'WISTERIA', code: '#8e44ad' }, { name: 'MIDNIGHT BLUE', code: '#2c3e50' },
      { name: 'SUN FLOWER', code: '#f1c40f' }, { name: 'CARROT', code: '#e67e22' },
      { name: 'ALIZARIN', code: '#e74c3c' }, { name: 'CLOUDS', code: '#ecf0f1' },

      { name: 'PUMPKIN', code: '#d35400' }, { name: 'POMEGRANATE', code: '#c0392b' },
      { name: 'SILVER', code: '#bdc3c7' }, { name: 'ASBESTOS', code: '#7f8c8d' },
    ];

    return (
      <FlatGrid
        itemDimension={130}
        items={items}
        style={styles.gridView}
        // staticDimension={300}
        // fixed
        // spacing={20}
        renderItem={({ item, index }) => (
          <View style={[styles.itemContainer, { backgroundColor: item.code }]}>
            <Text style={styles.itemName}>{item.name}</Text>
            <Text style={styles.itemCode}>{item.code}</Text>
          </View>
        )}
      />
    );
  }
}

const styles = StyleSheet.create({
  gridView: {
    marginTop: 20,
    flex: 1,
  },
  itemContainer: {
    justifyContent: 'flex-end',
    borderRadius: 5,
    padding: 10,
    height: 150,
  },
  itemName: {
    fontSize: 16,
    color: '#fff',
    fontWeight: '600',
  },
  itemCode: {
    fontWeight: '600',
    fontSize: 12,
    color: '#fff',
  },
});
