Hot reload not working

[anandrikka]

Hi,
Thanks for the amazing work. I encountered a problem, where hot reload not working for the screens inside the navigator. Here is my code

class App extends StatefulWidget {
  @override
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  final Map<TabItem, Map<String, Object>> _navItems = {
    TabItem.CALCULATOR: {
      'icon': FlutterIcons.calc,
      'title': 'Calculator',
      'pageTitle': 'Stock Calculator',
      'key': GlobalKey<NavigatorState>()
    },
    TabItem.ACCOUNTS: {
      'icon': Icons.insert_chart,
      'title': 'Accounts',
      'pageTitle': 'Accounts',
      'key': GlobalKey<NavigatorState>()
    },
    TabItem.SETTINGS: {
      'icon': Icons.settings,
      'title': 'Settings',
      'pageTitle': 'Settings',
      'key': GlobalKey<NavigatorState>()
    },
  };

  TabItem _currentTab = TabItem.CALCULATOR;

  Widget _renderPage() {
    Map<String, Object> item = _navItems[_currentTab];
    var key = item['key'] as GlobalKey<NavigatorState>;
    var pageTitle = item['pageTitle'] as String;
    switch (_currentTab) {
      case TabItem.CALCULATOR:
        return HomePage(
          key: key,
          title: pageTitle,
        );
        break;
      case TabItem.ACCOUNTS:
        return AccountsPage(
          key: key,
          title: pageTitle,
        );
        break;
      case TabItem.SETTINGS:
        return SettingsPageNavigator(
          navigatorKey: key,
          tabItem: TabItem.SETTINGS,
        );
        break;
      default:
        return HomePage(
          key: key,
          title: pageTitle,
        );
    }
  }

  @override
  Widget build(BuildContext context) {
    return WillPopScope(
      onWillPop: () async {
        bool flag = true;
        try {
          if (TabItem.SETTINGS == _currentTab) {
            final isFirstRouteInCurrentTab = await (_navItems[_currentTab]
                    ['key'] as GlobalKey<NavigatorState>)
                .currentState
                .maybePop();
            if (isFirstRouteInCurrentTab) {
              _onTabSelect(TabItem.SETTINGS);
              flag = false;
            }
          }
        } catch (e) {}
        return flag;
      },
      child: Scaffold(
        backgroundColor: Colors.red,
        body: _renderPage(),
        bottomNavigationBar: BottomNavigationBar(
          backgroundColor: Theme.of(context).primaryColor,
          unselectedItemColor: Colors.white54,
          selectedItemColor: Colors.white,
          onTap: (index) => _onTabSelect(TabItem.values[index]),
          currentIndex: _currentTab.index,
          elevation: 5,
          type: BottomNavigationBarType.fixed,
          items: [
            _buildNavItem(tabItem: TabItem.CALCULATOR),
            _buildNavItem(tabItem: TabItem.ACCOUNTS),
            _buildNavItem(tabItem: TabItem.SETTINGS),
          ],
        ),
      ),
    );
  }

  _onTabSelect(TabItem tab) {
    setState(() {
      _currentTab = tab;
    });
  }

  BottomNavigationBarItem _buildNavItem({TabItem tabItem}) {
    return BottomNavigationBarItem(
        icon: Icon(_navItems[tabItem]['icon']),
        title: Text(_navItems[tabItem]['title']));
  }
}
