class MainUiPage extends StatefulWidget {
  const MainUiPage({Key? key}) : super(key: key);

  @override
  _MainUiPageState createState() => _MainUiPageState();
}


class _MainUiPageState extends State<MainUiPage> with SingleTickerProviderStateMixin{

  TabController? _tabController;

  @override
  void initState() {
    _tabController = TabController(length: 3, vsync: this);
    super.initState();
  }

  @override
  void dispose() {
    super.dispose();
    _tabController?.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(

here is the sample code I had done, but it doesn't work correctly , anyone how to do this please help , I'm new to this.

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,
                    color: Colors.red,
                  ),
                ),
              ),

                  ),
                ),
              ),
            ],
          )
