I have a frontend design issue: such as below design when I want to open a new page in my home page I want to show it just like that. New page onto my existent page(blurry background). Is there any simple way in Flutter for this issue? Thanks in advance.

Try it like this

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Code Sample';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const MyStatelessWidget(),
      ),
    );
  }
}

class MyStatelessWidget extends StatelessWidget {
  const MyStatelessWidget({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Center(
      child: ElevatedButton(
        child: const Text('showModalBottomSheet'),
        onPressed: () {
          showModalBottomSheet<void>(
            context: context,
            builder: (BuildContext context) {
              return Container(
                height: 200,
                color: Colors.amber,
                child: Center(
                  child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    mainAxisSize: MainAxisSize.min,
                    children: <Widget>[
                      const Text('Modal BottomSheet'),
                      ElevatedButton(
                        child: const Text('Close BottomSheet'),
                        onPressed: () => Navigator.pop(context),
                      )
                    ],
                  ),
                ),
              );
            },
          );
        },
      ),
    );
  }
}
