| Props | Type | Description | Default |
|---|---|---|---|
| bricks | array | A list of Object:Bricks to be passed into the row renderer. I.E:,bricks=[{id: 1, uri: 'https://image.jpg', onPress: (brick) => this.redirect(brick.id)}, {id: 2, uri: 'https://hyper.jpg'}] |
[] |
| columns | num | Desired number of columns | 2 |
| sorted | bool | Whether to sort bricks according to their index position or allow bricks to fill in as soon as the uri is ready. |
false |
| imageContainerStyle | object | The styles object which is added to the Image component | {} |
| customImageComponent | React.Component |
Use a custom component to be rendered for the Image. This will work properly, as long as the component follows the standard interface of the react-native image component. | n/a |
| customImageProps | object | Pass along additional properties to a props.customImageComponent. |
n/a |
| spacing | num | Gutter size of the column. The spacing is a multiplier of 1% of the available view. | 1 |
| refreshControl | React.Component |
A component to be used as a refresh element for the Masonry component | n/a |
"Bricks" are the basic building block of the masonry and are passed into the props.bricks. They essentially represent the items within each column and require a uri property at a minimum. However, you can freely add additional properties to the data property if you need access to certain data within your brick.onPress handler and footer/header renderer. The following properties are available.
| Property | Type | Required | Description | Example |
|---|---|---|---|---|
| uri | string |
โ | The uri of the image location. | http://test.com/i.jpeg |
| key | string |
๐ซ | Optional item key. By default, uri is used as the key for each item. It's recommended to set a unique key here, but it is not required. The key is required if you need to have image with the same uri more than once in your list. |
image01 |
| onPress | func (brick.data) |
๐ซ | A function handler when the brick is pressed. The function will be called with the instance of the brick, which provides it's dimensions, columns, as well as any user defined properties passed into the bricks prop. An image will be wrapped by a TouchableHighlight. |
onPress: (data) => goTo(data.id) |
| renderHeader | func (brick.data) |
๐ซ | A function that is executed ABOVE the brick image, this function must return a React Component. renderHeader() is passed brick.data to allow dynamic content rendering of components. |

| renderFooter | func (brick.data) |
๐ซ | A function that is executed BELOW the brick image renderFooter() is passed brick.data to allow dynamic content rendering of components. |

Accomplishing a top bar indicating the user's avatar and name
{
// User defined data
data: {
user: {
name: 'Henry',
profilePic: 'https://user.jpeg'
}
}
uri: 'https://example.com/mainImage.jpeg',
renderHeader: (data) => {
return (
<View>
<Image source={{ uri: data.user.profilePic }} style={{ width: 50, height: 50}}>
<Text>{data.user.name}</Text>
</View>
);

Creating a bottom bar to include additional metadata
{
data: {

renderFooter: (data) => {
return (

<Text>{data.caption}</Text>
</View>
);

}โน๏ธ Figure 3: Using Third-Party Image Components
How to leverage third-party components like
<FastImage>and apply unique properties across all images
import FastImage from 'react-native-fast-image';
const fastProps = {
onProgress: { e => console.log(e.nativeEvent.loaded / e.nativeEvent.total) },
resizeMode: FastImage.resizeMode.contain
};
// ... Where Masonry is called
<Masonry
bricks={data}
customImageComponent={FastImage}
customImageProps={fastProps} />Pull requests are welcomed, just abide by rules listed within contributing.json.
