Tab navigation, to update how pages are navigated check in tab_navigation.dart, in this page you will be able to update which pages are navigated based on navigator index.  In this page you will find a Map of Tabindex and widgetBuilder
​
Map<TabIndex, WidgetBuilder> _routeBuilders(BuildContext context) {
  return {
    TabIndex.scan: (context) =>  ScannerPage(settings),
    TabIndex.setting: (context) => SettingsPage(callback),
    TabIndex.history: (context) => HistoryPage(settings),
  };
}
​
which is assigned to 
var routeBuilders = _routeBuilders(context);
identifying which page to serve when menu item is clicked, the application used TabIndex found in bottom_navigation.dart
enum TabIndex { scan, history, setting }
​
class TabIndexHelper {
  static TabIndex item({int index}) {
    switch (index) {
      case 0:
        return TabIndex.scan;
      case 1:
        return TabIndex.history;
//      case 2:
//        return TabIndex.create;
      case 2:
        return TabIndex.setting;
    }
    return TabIndex.scan;
  }
​
  static index(TabIndex tabIndex) {
    switch (tabIndex) {
      case TabIndex.scan:
        return 0;
      case TabIndex.history:
        return 1;
//      case TabIndex.create:
//        return 2;
      case TabIndex.setting:
        return 2;
