certainly! in this tutorial, we'll go through how to create a google-style navigation bar using flutter. flutter provides a convenient way to create a bottom navigation bar using the `bottomnavigationbar` widget. we'll also use a `pageview` to switch between different screens when the user taps on the navigation items.

prerequisites
make sure you have flutter installed on your machine. you can find the installation guide on the [official flutter website](https://flutter.dev/docs/get-started/....

step 1: create a new flutter project
create a new flutter project by running the following command in your terminal:

```bash
flutter create google_nav_bar_example
cd google_nav_bar_example
```

step 2: update `pubspec.yaml`
you may want to use a package to enhance the ui. for this example, we’ll use the `google_nav_bar` package. open your `pubspec.yaml` file and add the dependency:

```yaml
dependencies:
flutter:
sdk: flutter
google_nav_bar: ^6.0.0 check for the latest version on pub.dev
```

then, run `flutter pub get` to install the package.

step 3: create the main structure
now, let's create the main structure for your app. open `lib/main.dart` and update the code as follows:

```dart
import 'package:flutter/material.dart';
import 'package:google_nav_bar/google_nav_bar.dart';

void main() {
runapp(myapp());
}

class myapp extends statelesswidget {
@override
widget build(buildcontext context) {
return materialapp(
title: 'google nav bar example',
theme: themedata(
primaryswatch: colors.blue,
),
home: homescreen(),
);
}
}

class homescreen extends statefulwidget {
@override
_homescreenstate createstate() = _homescreenstate();
}

class _homescreenstate extends statehomescreen {
int _selectedindex = 0;

final listwidget _pages = [
center(child: text('home')),
center(child: text('search')),
center(child: text('profile')),
];

void _onitemtapped(int index) {
setstate(() {
