Lottie component for React Native (iOS and Android)

Lottie is a mobile library for Android and iOS that parses [Adobe After Effects](http://www.adobe.com/products/aftereffects.html) animations exported as JSON with [bodymovin](https://github.com/bodymovin/bodymovin) and renders them natively on mobile!

For the first time, designers can create **and ship** beautiful animations without an engineer painstakingly recreating it by hand.

## Getting Started

Get started with Lottie by installing the node module with yarn or npm:

```
yarn add lottie-react-native
```

or

```
npm i --save lottie-react-native
```

**_ IMPORTANT _**

Apps using older versions of React Native **_(RN < 0.59)_** should use `lottie-react-native` **_2.5.11_** due to AndroidX support being introduced only by React Native 0.59.

Therefore, any app running on RN <= 0.58.4 has to install lottie as follows:

```
yarn add lottie-react-native@2.5.11
```

or

```
npm i --save lottie-react-native@2.5.11
```

## iOS

Use `react-native link` to add the library to your project:

```
react-native link lottie-ios
react-native link lottie-react-native
```

After this, open the Xcode project configuration and add the `Lottie.framework` as `Embedded Binaries`.

## Android

For android, you can `react-native link` as well:

```
react-native link lottie-react-native
```

## Usage

(If you are using TypeScript, please read [this first](/docs/typescript.md))

LottieView can be used in a declarative way:

```jsx
import React from 'react';
import LottieView from 'lottie-react-native';

export default class BasicExample extends React.Component {
  render() {
    return <LottieView source={require('./animation.json')} autoPlay loop />;
  }
}
```

Additionally, there is an imperative API which is sometimes simpler.

```jsx
import React from 'react';
import LottieView from 'lottie-react-native';

export default class BasicExample extends React.Component {
  componentDidMount() {
    this.animation.play();
    // Or set a specific startFrame and endFrame with:
    this.animation.play(30, 120);
  }

  render() {
    return (
      <LottieView
        ref={animation => {
          this.animation = animation;
        }}
        source={require('../path/to/animation.json')}
      />
    );
  }
}
```

Lottie's animation progress can be controlled with an `Animated` value:

```jsx
import React from 'react';
import { Animated, Easing } from 'react-native';
import LottieView from 'lottie-react-native';

export default class BasicExample extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      progress: new Animated.Value(0),
    };
  }

  componentDidMount() {
    Animated.timing(this.state.progress, {
      toValue: 1,
      duration: 5000,
      easing: Easing.linear,
    }).start();
  }

  render() {
    return (
      <LottieView source={require('../path/to/animation.json')} progress={this.state.progress} />
    );
  }
}
```

## API

You can find the full list of props and methods available in our [API document](https://github.com/airbnb/lottie-react-native/blob/master/docs/api.md). These are the most common ones:

| Prop           | Description                                                                                                                                                                                                                                                                     | Default                                                                                                             |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- |
| **`source`**   | **Mandatory** - The source of animation. Can be referenced as a local asset by a string, or remotely with an object with a `uri` property, or it can be an actual JS object of an animation, obtained (for example) with something like `require('../path/to/animation.json')`. | _None_                                                                                                              |
| **`style`**    | Style attributes for the view, as expected in a standard [`View`](https://facebook.github.io/react-native/docs/layout-props.html).                                                                                                                                              | The `aspectRatio` exported by Bodymovin will be set. Also the `width` if you haven't provided a `width` or `height` |
| **`loop`**     | A boolean flag indicating whether or not the animation should loop.                                                                                                                                                                                                             | `true`                                                                                                              |
| **`autoPlay`** | A boolean flag indicating whether or not the animation should start automatically when mounted. This only affects the imperative API.                                                                                                                                           | `false`                                                                                                             |
