Welcome to a step-by-step guide on how to create a secure and minimalist chat experience using Enigma. With features like end-to-end encryption, customizable authentication, and a sleek UI, Enigma is designed to prioritize user privacy and simplicity.

Getting Started with Enigma

Before diving into the app’s configuration, it’s essential to have Flutter installed on your machine. If you’re a rookie, here’s the link to get you started:

• Flutter – Get Started

Setting Up Firebase

Because Enigma relies on Firebase services for its backend, you’ll need to set up a Firebase project and configure several features:

• Create a new Firebase Project.
• Enable the following services:
• Firebase Phone Authentication (for authentication)
• Cloud Firestore (this is crucial; avoid using Realtime Database)
• Firebase Storage (to store images)
• Firebase In-App Messaging (for sending custom messages)
• Download the google-services.json file and place it in the android/app folder.
• Run flutter packages get to download the required packages.
• Using a device or an emulator, execute flutter run to run the app.

Implementing Notifications

To enable notifications in your app, follow these instructions:

1. Enable FCM in your Firebase Console.
2. Copy the functions directory to the root of your project, as notifications utilize Cloud Functions.
3. Install firebase-cli if you haven’t already, and then execute firebase deploy --only functions.

Firebase Rules for Storage and Cloud Firestore

For enhanced security, you can set up Firebase rules. The basic rule looks like this:

allow read, write: if request.auth.uid != null;

Feel free to make these rules more stringent based on your app’s requirements. For detailed guidance, check out Get Started on Writing Rules.
