Once you know the architecture of this, you would be able to use it for any kind of e-commerce or shopping with backend. All you need to do is change the pictures and products' names.
State management
This e-commerce app is based on flutter Getx Package. We used Getx package to manage the state and routing of the app. We have also used Getx for api client.
Getx is a great package for managing your app states, routes and http client. It does more than that. If you are trying to build a complex mobile or web app using flutter, Getx would be your best choice. And it's also beginners friendly reactive state management app package.
We used Getx for products display, maintaining the state of the shopping cart, profile page, google map and many other features of this e-commerce app or shopping app.
Backend
We have used Laravel for building the backend of this app. We used the same framework for building Restful Api for the app. Laravel is the most popular web application framework both for backend and api building. Backend shows users' orders, total orders, users' info, payment info etc.

Installation
Flutter android studio windows installation
PHP =>7.3 or above
Laravel =>8.0
Admin panel windows installation
To install the admin panel in local host on windwos, follow the video below.
The above video shows how to download the admin panel for e-commerce app and install it in a local windows machine. The admin panel is based on Laravel framework. The admin panel requires prior installation knowledge of laravel framework on local machine.
But if you have never installed laravel framework, watch the video from the link below.
Admin panel mac installation
To install the admin panel in local host on mac, follow the video below.
The above video shows how to download the admin panel for e-commerce app and install it in a local mac machine. The admin panel is based on Laravel framework. The admin panel requires prior installation knowledge of laravel framework on local machine mac.
But if you have not installed Laravel Framework on mac watch video in the link below
Flutter sdk: ">=2.12.0 <3.0.0"
The backend is done with Laravel. Download the code from the patreon and install in your local or server. The mysql database is included there. After installing you will see the backend. Type in your domain with /admin. The defualt password is admin and password is admin too.
Make sure you give permission to /storage folder. In general it's 775. If it doesn't work then try 777.
Change the base url in your flutter app. Use your own domain
Google Map Api Key
Make user that, you enable google map service from google. If you don't know how to do it, follow the tutorial here. After enabling you need to use your own api key in the app
When you set up Api key, you need to set up in two pairs
First pair
It's android users. If you use android then you need to set up google api key both for android and it's web version.
Second pair
It's for iOS users. If you use iOS then you need to set up google api key both for iOS and web version. But this web version api key should be the same as android web version.
So you need three google api key, one for ios, one for android and one for web api.
One of the errors you might get
API keys with referer restrictions cannot be used with this API.
This means you have set up wrong api key.
Error getting the google api
Watch the video to verify your local testing with google map
About the backend technology used in the app
If you are trying to upload images from the backend, you need to make changes in .env file.
In the .env file make a little change in the APP_URL.
APP_URL=http://127.0.0.1:8000/You see how we put the slash at the end.
Part 4 requires you to create a new table name zones for zone based services. Follow the video to create a table.
You also need to have model name Zone.php in the app/Models/ folder. And put the code in the file from the link below
Use PhpMyAdmin to make the database table zones
If you hosting it in shared host, after visiting in the brower, you might get like this
This means, your site in shared hosting setting problems and website is not able point to the public folder of Laravel.
To solve this create .htaccess file in the root folder of your project and put the code in .htaccess file
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]Learn more about it here htaccess file
If the above solution did not work, then tryin the .htaccess. file
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !^public
RewriteRule ^(.*)$ public/$1 [L]
Our e-commerce or shopping app does payment. We implemented payment using paypal sdk using webview. Part of the code is given here in the link below
Payment requires special settings in the payment view page. We need to read this from the backend database.
Follow the link below and put the code according to the link
Otherwise you will get error
LogicException: Unable to read key from file file://C:\xampp\htdocs\shopping-app\storage\oauth-private.key in file C:\xampp\htdocs\shopping-app\vendor\league\oauth2-server\src\CryptKey.php
To solve it you need to run the below command
php artisan passport:install7. You may have error in the payment section when you access user information in the backend code. The error could be like below
To solve this make some changes in the PayPalPaymentController.php file
$number = sprintf("%0.2f", $order['order_amount']);
$item->setName(session('f_name'))
->setCurrency(Helpers::currency_code())
->setQuantity(1)
->setPrice($number);We have inserted session('f_name') inside setName().
8. Laravel Toastr package issues
Laravel toastr package may cause issues, it mostly does due to path is incorrect. Check out the video below to solve this issue
Flutter Frontend Issues
For the app in the part 3, you might have trouble resigtering new users. You might get forbidden error. That happens because change login method. So you need to make a change in your app. You may continue to finish part 3 or you can fix this first and then continue. If you decide to fix this issue first then watch the video in the link
This app downloads data from the internet. Your android emulator might have insecure settings. it happens due to http rather than https. Try the solutions in the link below
Connection closed while receiving data
If you have more errors go to the link below
If you get the above error try to add this in your ApiClient.dart
"HttpHeaders.contentTypeHeader": "application/json"
Then your _mainHeaders variable would look like below
_mainHeaders={
'Content-type':'application/json; charset=UTF-8',
'Authorization': 'Bearer $token',
"HttpHeaders.contentTypeHeader": "application/json"
};The above error should be caused by image loading. And If the above solution did not work for you then you can try below solution. Use cache for network image
https://learnflutter.co/flutter-order-model-for-payment/
Copy all the code from the link above and put in the models folder as order_model.dart
https://learnflutter.co/flutter-place-order-model-for-e-commerce-app/
Copy all the code from the above link and put in the models folder name place_order_model.dart
With this we incapsulate all the information about the order.
We missed a line in google map.
Address does not show up even after filling in the address in account_page.dart
in account_page.dart inside build method add the line
