Answer 1

I do not understand what you mean by controlling tabs but check the below code for tab bar implementation, along with drawers and appbar action icons.
class HomeScreen extends StatelessWidget {
const HomeScreen({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 3, //this is the number of tabs you need -- for your case it is 3
child: Scaffold(
appBar: AppBar(
backgroundColor: Colors.brown[500],
actions: [
IconButton(onPressed: () {
//This is to show a snackbar message when search button is pressed. Remove it and put your own onpressed action code
ScaffoldMessenger.of(context).showSnackBar(
SnackBar(
content: const Text("Search Button Pressed"),
behavior: SnackBarBehavior.floating,
margin: const EdgeInsets.all(20),
shape: const StadiumBorder(),
action: SnackBarAction(
label: 'Dismiss',
disabledTextColor: Colors.white,
textColor: Colors.blue,
onPressed: () {
//Do whatever you want
},
),
),
);
}, icon: const Icon(Icons.search)),
],
bottom: const TabBar(
//customise your tabs here
indicatorColor: Colors.white,
indicatorSize: TabBarIndicatorSize.label,
indicatorWeight: 5,
labelStyle: TextStyle(fontSize: 16.0, fontWeight: FontWeight.bold),
tabs: [
//add your tabs here. if you add more tabs make sure you increase the length above
Tab(text: 'Doctor', iconMargin: EdgeInsets.zero,),
Tab(text: 'Community',),
Tab(text: 'Calls',),
],
),
),
//This is your app drawer
drawer: Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: [
const DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text('Drawer Header'),
),
ListTile(
title: const Text('Item 1'),
onTap: () {},
),
ListTile(
title: const Text('Item 2'),
onTap: () {},
),
],
),
),
body: const TabBarView(
//This is the view of all the tabs. The first children in the list is the first item in tabs.
children: [
Center(child: Text('Doctor Page', style: TextStyle(fontWeight: FontWeight.bold, fontSize: 30),)),
Center(child: Text('Community Page', style: TextStyle(fontWeight: FontWeight.bold, fontSize: 30),)),
Center(child: Text('Calls Page', style: TextStyle(fontWeight: FontWeight.bold, fontSize: 30),)),
],
),
),
);
}
}
Output:
