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](https://facebook.github.io/react-native/docs/flatlist.html) and [SectionList](https://facebook.github.io/react-native/docs/sectionlist.html).

**Version 3.x, please refer [v3 branch](https://github.com/saleel/react-native-super-grid/tree/v3) for documentation**  

**Version 2.x and older, please refer [v2 branch](https://github.com/saleel/react-native-super-grid/tree/v2) for documentation**  


### Versions

- Use version `6.0.0` for RN `0.74.0` and above
- Use version `5.1.0` for older versions of RN


### Installing

You can install the package via npm.

```
npm install react-native-super-grid
```



### Usage (FlatGrid)
```javascript
import { FlatGrid } from 'react-native-super-grid';
```
```javascript
<FlatGrid
  itemDimension={130}
  data={[1,2,3,4,5,6]}
  renderItem={({ item }) => (<Text>{item}</Text>)}
/>
```


### Usage (SimpleGrid)
This component is similar to the FlatGrid but does not use a FlatList, instead, it simply maps over the data items. This is useful if you need to put a grid inside a ScrollView or if you have a small array.
```javascript
import { SimpleGrid } from 'react-native-super-grid';
```
```javascript
<SimpleGrid
  itemDimension={130}
  data={[1,2,3,4,5,6]}
  renderItem={({ item }) => (<Text>{item}</Text>)}
/>
```

### Usage (SectionGrid)

```javascript
import { SectionGrid } from 'react-native-super-grid';
```
```javascript
<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](https://facebook.github.io/react-native/docs/flatlist.html) styles (Object) |  | Styles for the container. Styles for an item should be applied inside ```renderItem```. Note: If you set `adjustGridToStyles` to `true` then padding added in this prop will be used to adjust the total dimensions of the grid to reflect the padding in this style object. |
| additionalRowStyle | styles (Object) | | Additional styles for rows (rows render multiple items within), apart from the generated ones.
| 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. Note: If you set `adjustGridToStyles` to `true` then you can alternatively use the `contentContainerStyle` prop and set `maxWidth` or `maxHeight`.|
| 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.|
| invertedRow | boolean | | Reverses the direction of row items. It can be used with the [`inverted`](https://reactnative.dev/docs/flatlist#inverted) property.|
| maxItemsPerRow | number | | Specifies the maximum number of items to render per row|
| contentContainerStyle | styles (Object) | | This is the regular FlatList/SectionList prop. If you set `adjustGridToStyles` to `true` and specify `maxWidth` or `maxHeight` it will be used the same as `maxDimension`. In addition, padding added here will be used to adjust the total dimensions of the grid to reflect the padding in this style object.|
| adjustGridToStyles | boolean | | Set to true when you want the library to automatically adjust the total dimensions of the grid based on `style` and `contentContainerStyle` props |
| customFlatList (for FlatGrid) | ElementType | | Replaces `FlatList` in FlatGrid with ElementType. E.g. `Animated.FlatList` |
| customSectionList (for SectionGrid) | ElementType | | Replaces `SectionList` in SectionGrid with ElementType. E.g. `Animated.SectionList` |
| onItemsPerRowChange | Function | | A callback `(itemsPerRow: number) => void` that is called when number of items per row is determined. |

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.

#### Full width items

To make an item full width, simply include `_fullWidth: true` in the data object for that item. For example: 

```javascript
{ name: 'TURQUOISE', code: '#1abc9c', _fullWidth: true }
```
