That happens because you are not destructuring it from the props as you have done in your render() function

onPressButton = () => {
    var {navigate} = this.props.navigation;
    var options = {
      title: strings.app_name,
      content: strings.create_message,
      positiveText: strings.OK,
      onPositive: () => navigate("DashboardScreen")
    };
    var dialog = new DialogAndroid();
    dialog.set(options);
    dialog.show();
  }
