secure_flutter #

A Flutter plugin for secure API key validation using bundle ID and server-side verification.

Features #

• Secure API key validation with backend verification

• Uses package info to send app bundle ID and version info

• Easy integration with .env for storing API keys securely

• Throws exceptions on invalid keys or network failures

Getting Started #

1. Register your app and get API key #

Go to https://jasperazerbaijan.com/developers

Register your app by providing your app's bundle ID (Android package name or iOS bundle identifier).

After registration, you will receive an API key.

2. Add .env file #

Create a .env file at the root of your Flutter project and add your API key like this:

API_KEY=your_api_key_here

Make sure your .env file is added to your app assets by updating your #

pubspec.yaml:

flutter:

assets:

- .env

Important: Add .env to your .gitignore file to keep your API key secure and avoid uploading it to version control.

Usage Example #

import 'package:secure_flutter/secure_flutter.dart';

import 'package:flutter/material.dart';

  

Future<void> main() async {

WidgetsFlutterBinding.ensureInitialized();

  

// Load environment variables from .env file

await dotenv.load(fileName: ".env");

  

final apiKey = dotenv.env['API_KEY'] ?? '';

await SecureFlutter.init(apiKey);

  

runApp(const MyApp());

}

  

class MyApp extends StatelessWidget {

const MyApp({super.key});

  

@override

Widget build(BuildContext context) {

return const MaterialApp(

home: Scaffold(

body: Center(

child: Text('Secure Flutter Plugin'),

),

),

);

}

}

Error Handling #

If the API key is invalid or verification fails, an exception is thrown.

Network or server errors also throw exceptions.

You should handle exceptions when calling SecureFlutter.init().
