1. Create common layout

widgets/CommonLayout.dart

            import 'package:flutter/material.dart';

              class CommonLayout extends StatelessWidget {
                final Widget child;

                CommonLayout({required this.child});

                @override
                Widget build(BuildContext context) {
                  return Scaffold(
                    appBar: AppBar(
                      title: Text('Common Title'), // You can customize this as needed
                    ),
                    body: Padding(
                      padding: EdgeInsets.all(16.0),
                      child: child,
                    ),
                  );
                }
              }


              

This CommonLayout widget has an AppBar and a body area where you can pass any child widget to be displayed.
