Demonstrates the Implementation of Envify Package in Flutter.

Envify - Your Secret Vault in Flutter

As a Flutter Developer, there comes a time when you need to specify some confidential information in your source code such as API Keys, File Paths, URLs, Client-Side Secret Key etc, so the question arises that how would you:

✔️ Keep this data confidential.

💉 Integrate it without disclosing it inside the source code.

🛡️ Protect it if a hacker dismantles the code.

To get into more details, read the medium article.

Getting Started

1. Add the envify package in the pubspec.yaml file.

   dependencies:
       flutter:
       sdk: flutter
       # A better way to handle environment variables using `.env` file.
       envify: ^2.0.2
   
   dev_dependencies:
       
       # A build system for Dart code generation and modular compilation.
       build_runner: ^2.1.5
   
       # A code generator for envify.
       envify_generator: ^2.0.2

2. Add all the files related to envify in the .gitignore file.

   # Some files to ignore.....
   
   # Envify related 
   .env
   env.dart
   env.g.dart

3. Outside the lib folder, create an Environment file.

   API_KEY = 'PWEP198104102HEWFUQ'
   SITE_KEY = '91310!@31rwd2PZECAA'
   CLIENT_SECRET = 'XXXAd0q39e20q'
   CLIENT_ID = 'John Doe'

4. Under the config folder, create an env.dart file

   import 'package:envify/envify.dart';
   part 'env.g.dart';
   
   @Envify(name: 'Secret')
   abstract class Secret {
       /// Holds the API_KEY.
       static const api_key = _Secret.api_key;
   
       /// Holds the SITE_KEY.
       static const site_key = _Secret.site_key;
   
       /// Holds the CLIENT_SECRET.
       static const client_secret = _Secret.client_secret;
   
       /// Holds the CLIENT_ID.
       static const client_id = _Secret.client_id;
   }

5. Generate the env.g.dart using the below command from the terminal.

   flutter pub run build_runner build --delete-conflicting-outputs
