Please check this out.

import 'package:flutter/material.dart';

const Color darkBlue = Color.fromARGB(255, 18, 32, 47);

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.dark().copyWith(
        scaffoldBackgroundColor: darkBlue,
      ),
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: MyWidget(),
        ),
      ),
    );
  }
}

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.separated(itemBuilder : (BuildContext context , int i) {
         return   _innerWidget();
                
    } , itemCount : 2 , shrinkWrap: true,separatorBuilder: (context, index) => SizedBox(height: 10.0), );
  }
}

Widget  _innerWidget(){
  return  ListView.builder(itemBuilder : (BuildContext context , int i) {
  
        return Text('hello');
 
    }, itemCount: 2,shrinkWrap: true, physics: NeverScrollableScrollPhysics(),);
