## Usage

```javascript
var Platform = require('react-native').Platform;
var VideoTrimPicker = require('react-native-video-trim-picker');

// More info on all the options is below in the README...just some common use cases shown here
var options = {
  title: 'Pick and Trim Video',
  customButtons: [
    {name: 'trim', title: 'Trim Video Now'},
  ],
  storageOptions: {
    skipBackup: true,
    path: 'images'
  },
  customStyles: {
  	pickvideo: { height: 35 },
  	trimvideo: { alignSelf: 'center' },
  	containerTrimmerBottomView:{ flexDirection:'column'},
  	sliderValuesView:{ justifyContent:'space-between'},
  	sliderValuesText1: { fontSize: 18,  color: 'black'},
  	sliderValuesText2: { fontSize: 18,  color: 'black'},
  	backgroundView: { flexDirection:'column'	},
  	backgroundViewTrimmer: {	  alignItems:'center' 	}
  }
};

/**
 * The first arg is the options object for customization (it can also be null or omitted for default options),
 * The second arg is the callback which sends object: response (more info below in README)
 */
VideoTrimPicker.showVideoTrimPicker(options, (response) => {
  console.log('Response = ', response);

  if (response.didCancel) {
    console.log('User cancelled video picker');
  }
  else if (response.error) {
    console.log('VideoTrimPicker Error: ', response.error);
  }
  else if (response.customButton) {
    console.log('User tapped custom button: ', response.customButton);
  }
  else {
    // You can display the video using either data...
    const source = {uri: 'data:video/mp4;base64,' + response.data, isStatic: true};
    // or a reference to the platform specific asset location
    if (Platform.OS === 'ios') {
      const source = {uri: response.uri.replace('file://', ''), isStatic: true};
    } else {
      const source = {uri: response.uri, isStatic: true};
    }

    this.setState({
      myTrimmedVideoSource: source
    });
  }
});
```

Then later, if you want to display this video in your render() method:
```javascript
<Video source={this.state.myTrimmedVideoSource} />
```
