You need to do something like that.... wrap all your Container in a Stack and set Positioned of every Container.
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Welcome to Flutter',
home: Scaffold(
appBar: AppBar(
title: const Text('Welcome to Flutter'),
),
body: Container(
width: double.infinity,
child: Stack(
children: [
Positioned(
left: 0,
child: ClipPath(
clipper: CustomClipPathTopContainerOne(),
child: Container(
height: 50,
width: 200,
color: Colors.green,
),
),
),
Positioned(
left: 175,
child: ClipPath(
clipper: CustomClipPathTopContainerSecond(),
child: Container(
height: 50,
width: 200,

),
Positioned(

child: ClipPath(

child: Container(

}
}
class CustomClipPathTopContainerOne extends CustomClipper<Path> {
@override

double w = size.width;
