The issue I am facing is two appBar, I tried removing appBar from loggedIn.dart but Drawer hamburger icon is not showing, and I cannot remove appBar from emergencyHome.dart as I wont be able to add Tab bar. What is viable solution for this? Please help how to Structure by app and routes to easily manage navigation within app

Answer 1

Remove the appbar from EmergencyHome.dart
this will remove the second app title. But there will be that shadow from the first app bar so put elvation:0
so, this will look like one appbar now your drawer will also work.

Answer 2

you can use flexibleSpace in EmergencyHome.dart
DefaultTabController(
length: 3,
child: Scaffold(
appBar: AppBar(
flexibleSpace: Column(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
TabBar(
tabs: [
Tab(
//icon: Icon(Icons.more_vert),
text: "Report",
),
Tab(
text: "Ongoing",
),
Tab(
text: "Finished",
)
],
)
],
),
),
body: TabBarView(
children: [
ReportAnimalEmergency(),
OngoingAnimalEmergencies(),
FinishedAnimalEmergencies(),
],
),
)
);

Answer 3

You don't want to make two appbar to get the drawer property. Use DefaultTabController then inside that you can use scaffold.so, you can have drawer: Drawer() inside that you can also get a appbar with it with TabBar as it's bottom.
This is most suitable for you according to your use case.
i will put the full code below so you can copy it.
void main() {
runApp(const TabBarDemo());
}
class TabBarDemo extends StatelessWidget {
const TabBarDemo({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
home: DefaultTabController(
length: 3,
child: Scaffold(
drawer: Drawer(),
appBar: AppBar(
bottom: const TabBar(
tabs: [
Tab(
text: "report",
),
Tab(text: "ongoing"),
Tab(text: "completed"),
],
),
title: const Text('Tabs Demo'),
),
body: const TabBarView(
children: [
Icon(Icons.directions_car),
Icon(Icons.directions_transit),
Icon(Icons.directions_bike),
],
),
),
),
);
}
}
