Using react natives picker

I am trying out picker in my react native project and this example i took directly from the react native docs

<CardItem>
<Item  floatingLabel>
<Label>Airtime Amount</Label>
<Picker selectedValue={this.state.language} onValueChange={(lang) => this.setState({language: lang})}> <Picker.Item label="Java" value="java" /> <Picker.Item label="JavaScript" value="js" /></Picker>
</Item>
</CardItem>

This is the source http://facebook.github.io/react-native/docs/picker.html

I get the error

null is not an object (evaluating 'this.state.language')

How can i correct this. render

My class starts like this

class Form extends Component {

  static propTypes = {
    openDrawer: React.PropTypes.func,
  }
....

You need to creat the language and give a value

constructor(props) {
  super();
  this.state = {
    language: 'english', // or language: '',
  }
}
