react-native-super-grid

React Native Super Grid

Responsive Grid View for React Native.

Getting Started

This component renders a Grid View 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 or SectionList.

Installing

You can install the package via npm.

npm install react-native-super-grid

If your react native is below v0.49, install version 1.0.4 - npm install react-native-super-grid@1.0.4

Usage (GridView)

This is a FlatList modified to have a grid layout.

import GridView from 'react-native-super-grid';

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

Usage (SuperGridSectionList)

This is a SectionList modified to have a grid layout. sections and renderItem prop has same signature as of SectionList.

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

<SuperGridSectionList
  itemDimension={130}
  sections={[
    {
      title: 'Title1',
      data: [
        { 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' },
      ]
    },
    {
      title: 'Title2',
      data: [
        { 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' },
      ]
    },
    {
      title: 'Title3',
      data: [
        { name: 'BELIZE HOLE', code: '#2980b9' }, { name: 'CONCRETE', code: '#95a5a6' }, { name: 'ORANGE', code: '#f39c12' },
        { name: 'PUMPKIN', code: '#d35400' }, { name: 'POMEGRANATE', code: '#c0392b' },
        { name: 'SILVER', code: '#bdc3c7' }, { name: 'ASBESTOS', code: '#7f8c8d' }
      ]
    }
  ]}
  style={styles.gridView}
  renderItem={({ item }) => (
    <View style={[styles.itemContainer, { backgroundColor: item.code }]}>
      <Text style={styles.itemName}>{item.name}</Text>
      <Text style={styles.itemCode}>{item.code}</Text>
    </View>
  )}
  renderSectionHeader={({ section }) => (
    <Text style={{ color: 'green' }}>{section.title}</Text>
  )}
/>

Properties

Property	Type	Default Value	Description
renderItem	Function		Function to render each object. Should return a react native component.
items (or sections for SuperGridSectionList)	Array		Items to be rendered. renderItem will be called with each item in this array.
itemDimension (itemWidth if version 1.x.x)	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 the view child of the row
staticDimension	Number	undefined	Specifies a static width or height for the GridView container. If your container dimension is known or can be calculated at runtime (via Dimensions.get('window'), for example), passing this prop will force the grid container to that dimension size and avoid the reflow associated with dynamically calculating it
horizontal	boolean	false	If true, the grid will be scrolling horizontally (this prop doesn't affect the SuperGridSectionList, 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.

Note: If you want your item to fill the height when using a horizontal grid, you should give it a height of '100%'

Example Nested Grid (itemContainerStyle)

If you try to use nested grid with different number of items, you could use itemContainerStyle to change the style. Please take a look on the follow example.

import React, { Component } from 'react';
import { StyleSheet, View, Text } from 'react-native';
import GridView from 'react-native-super-grid';

const styles = StyleSheet.create({
  gridView: {
    paddingTop: 25,
    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',
  },
});

export default class Example extends Component {
  render() {
    // Taken from https://flatuicolors.com/
    const groupedItems = {
        'left': [
            { name: 'TURQUOISE', code: '#1abc9c' },
            { name: 'EMERALD', code: '#2ecc71' },
            { name: 'PETER RIVER', code: '#3498db' },
            { name: 'AMETHYST', code: '#9b59b6' },
            { name: 'WET ASPHALT', code: '#34495e' }
        ],
        'center': [
            { name: 'TURQUOISE', code: '#1abc9c' }
        ],
        'rigth': [
            { name: 'TURQUOISE', code: '#1abc9c' },
            { name: 'EMERALD', code: '#2ecc71' },
            { name: 'PETER RIVER', code: '#3498db' }
        ]
    }

    return (
      <GridView
          itemContainerStyle={{ justifyContent: 'flex-start' }}
          itemDimension={300}
          items={['left', 'middle', 'rigth']}
          style={styles.gridView}
          renderItem={title =>
              (
                  <GridView
                      listKey={title}
                      itemDimension={100}
                      items={groupedItems[title]}
                      style={styles.gridView}
                      renderItem={item => (
                          <View style={[styles.itemContainer, { backgroundColor: item.code }]}>
                              <Text style={styles.itemName}>{item.name}</Text>
                              <Text style={styles.itemCode}>{item.code}</Text>
                          </View>
                      )}
                  />
              )
          }
      />
    );
  }
