This component provides you a simple way to load a remote image and automatically set `Image` crossAxisSize to the image dimension which fits the provided mainAxisSize.

ReactNative `Image` component needs users to set both `mainAxisSize` and `crossAxisSize` props.

## Installation

`yarn add react-native-autosize-image`

`npm install react-native-autosize-image`

## Usage

Use local or remote files:

```js
import React, { Component } from 'react';
import AutoImage from 'react-native-autosize-image';

import image from 'gallifrey-falls.png';

export default class Demo extends Component {
  render() {
    return (
      <View>

        <AutoImage
          mainAxisSize={100}
          mainAxis='horizontal'
          source={image}
        />

        <AutoImage
          mainAxisSize={100}
          mainAxis='vertical'
          source={{uri: 'http://placehold.it/350x150'}}
        />

      </View>
    );
  }
}
```

You can even specify fallback images for when the source fails to load:

```js
import React, { Component } from 'react';
import AutoImage from 'react-native-autosize-image';

import image from 'gallifrey-falls.png';

export default class Demo extends Component {
  render() {
    return (
      <AutoImage
        mainAxisSize={100}
        source={{uri: 'https://vivaxy.github.io/404'}}
        fallbackSource={image}
      />
    );
  }
}
```
