A horizontal list view can be created by ListView.builder widget. By default scroll direction of this list is vertical hence you have to change it to horizontal : -
scrollDirection: Axis.horizontal,
Full Code : -
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'ListView',
theme: ThemeData(
primarySwatch: Colors.blue,
),
debugShowCheckedModeBanner: false,
home: const View(),
);
}
}
class View extends StatefulWidget {
const View({super.key});
#override
State<View> createState() => _ViewState();
}
class _ViewState extends State<View> {
List doctorName = ["A", "B", "C"];
#override
Widget build(BuildContext context) {
return Scaffold(

you can use bottomSheet to place your image.
Add the below code inside your Scaffold
bottomSheet: Container(
width: double.infinity,
child: Image(
image: AssetImage('Images/design1.png'),
colorBlendMode: BlendMode.overlay,
fit: BoxFit.fill,
),
),

You can also use a spacer to push the content down

Jumping to desired screens on pressing an item in Bottom Navigation Bar

I am writing a code in flutter and the screen with the bottom navigation bar looks like this.
What I want is that whenever I press the home button from the bottom navigation bar it should jump to the home screen, similarly for other screens like clicking the caregiver icon I want to move to Caregiver Screen and so on for others. I cannot figure this out by using BottomNaviagtionBar. Please help me out.

void onTabTapped(int index) {

P.S: I am still learning flutter
Thank you in advance!

Try to do this:
in your state class, put this at the beginning:
int _currentIndex = 0;
At the beginning of you build:
Widget build(BuildContext context) {
final _widgetOptions = [
Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ Stack(
children: [ Container( padding: EdgeInsets.symmetric(vertical: 22,
horizontal: 47),
CaregiverScreen(),
HistoryScreen(),
ProfileScreen()
];
This should be your body:
body: _widgetOptions.elementAt(_currentIndex),
