npm package: 23mofang-react-native-root-siblings
Description: react native root sibling elements manager
Latest version: 1.0.1

### react-native-root-siblings
---

Add sibling elements after your app root element.
The created sibling elements are above the rest of your app elements.
This can be used to create a `Modal` component or something should be over your app.

### Add it to your project

Run `npm install react-native-root-siblings --save`

### USAGE
This library can add element above the root app component registered by `AppRegistry.registerComponent`.

1. Create sibling element
```
let sibling = new RootSiblings(<View
    style={{top: 0,right: 0,bottom: 0,left: 0,backgroundColor: 'red'}}
/>);
```
This will create a View element cover all of your app elements,
and returns a sibling instance.
You can create a sibling anywhere inside your react native code.

2. Update sibling element
```
sibling.update(<View
    style={{top: 10,right: 10,bottom: 10,left: 10,backgroundColor: 'blue'}}
/>);
```
This will update the sibling instance to a View with blue backgroundColor and cover the screen by `10` offset distance.

3. Destroy sibling element
```
sibling.destroy();
```
This will remove the sibling element.

        let sibling = new RootSiblings(<View
            style={[styles.sibling, {top: id * 20}]}
        >
            <Text>I`m No.{id}</Text>
        </View>);
        id++;
        elements.push(sibling);

        lastId >= 0 && elements[lastId].update(<View
            style={[styles.sibling, {top: lastId * 20}]}
        >
            <Text>I`m No.{lastId} : {Math.random()}</Text>
