title: Call child function from parent component in React Native
body: <p>I'm developing my first React Native app. What I'm trying to achieve is to execute a child function from the parent component, this is the situation:</p>
  
  <p><strong>Child</strong></p>
  
  <pre><code>export default class Child extends Component {
    ...
    myfunct: function() {
      console.log('Managed!');
    }
    ...
    render(){
      return(
        &lt;Listview
        ...
        /&gt;
      );
    }
  }
  </code></pre>
  
  <p><strong>Parent</strong></p>
  
  <pre><code>export default class Parent extends Component {
    ...
    execChildFunct: function() {
      ...
      //launch child function "myfunct"
      ...
      //do other stuff
    }
  
    render(){
      return(
        &lt;View&gt;
          &lt;Button onPress={this.execChildFunct} /&gt;
          &lt;Child {...this.props} /&gt;
        &lt;/View&gt;);
    }
  }
  </code></pre>
  
  <p>In this example, I would like to log <code>'Managed!'</code> when I press the button in the parent class. How is it feasible?</p>
