Use NavigationRail widget to get your desire result. You will try like this...

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: CategoriesPage(),
    ),
   ),
  );
 }
}

class CategoriesPage extends StatefulWidget {
 @override
 _CategoriesPageState createState() => _CategoriesPageState();
}

class _CategoriesPageState extends State<CategoriesPage> {
  int _selectedIndex = 0;

  bool showNavigationBar = false;

  var list = [
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
   AllCategory(),
 ];

 var title = [
"All Category",
'WalkPage',
'LocationPage',
'NotificationPage',
'SettingsPage',
'SearchPage',
"All Category",
'WalkPage',
'LocationPage',
'NotificationPage',
'SettingsPage',
'SearchPage',
'LocationPage',
'NotificationPage',
'SettingsPage',
'SearchPage'
];

@override
Widget build(BuildContext context) {

here with the Help of Row and Expanded widget you can achieve your UI. here is the example of that.

           Scaffold(
              body: Row(
                children: [
                  Expanded(
                    flex: 2,
                    child: ListView.builder(
                      itemBuilder: (context, index) {
                        return ListTile(
                          title: Text("$index"),
                        );
                      },
                    ),
