I ran the following command to generate a new list screen, but it failed to update the AppNavigation.tsx

$> ignite generate list Groups

? How will your data be presented on this list? Single

AppNavigation.tsx currently looks like this:

import {StackNavigator} from 'react-navigation';
import GroupsScreen from '../Containers/GroupsScreen/GroupsScreen';
import SettingsScreen from '../Containers/SettingsScreen/SettingsScreen';
import LaunchScreen from '../Containers/LaunchScreen';

import styles from './Styles/NavigationStyles';

// Manifest of possible screens
const PrimaryNav = StackNavigator({
  GroupsScreen: {screen: GroupsScreen},
  SettingsScreen: {screen: SettingsScreen},
  LaunchScreen: {screen: LaunchScreen},
}, {
  // Default config for all screens
  headerMode: 'none',
  initialRouteName: 'LaunchScreen',
  navigationOptions: {
    headerStyle: styles.header,
  },
});

export default PrimaryNav;
