# Enigma



Enigma - A minimalist, locked-down one-to-one chat app.



## Usage



* [Flutter - Get Started](https://flutter.dev/docs/get-started/install)

* Since this is a Firebase dependent project, create a Firebase Project and enable

  * Firebase Phone Authentication (for authentication)

  * Cloud Firestore (not Realtime Database)

  * Firebase Storage (for storing images)

  * Firebase In-App Messaging (for custom messages)

* After enabling the above features, download the `google-services.json` and paste it in `android/app` folder.

* Do `flutter packages get` to get the packages.

* Use a device or an emulator and run `flutter run`.



## Notifications



1. Enable FCM in your Firebase Console.

2. Notifications use Cloud Functions. Copy the `functions` directory to the root of your project.

3. Do `firebase deploy --only functions` You need to have `firebase-cli` installed for this command to execute.

## Firebase Rules for Storage and Cloud Firestore



I've used the following basic rule



```

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

```



but you can be more restrictive if you so wish. For more info - [Get Started on Writing Rules](https://firebase.google.com/docs/firestore/security/get-started#writing_rules)



Get it on Google Play

## Features



**Authentication:** Passcode authentication is enabled which is needed to unlock hidden and locked chats. If your device supports fingerprint authentication, then you can use it as well.



**End-To-End Encryption:** Your messages are encrypted right from the moment you send it. This makes sure that only the recipient receives the message and NO ONE ELSE.



**Hide Chats:** You can hide chats to protect against prying eyes. YOU will have to authorize to unhide the chats.



**Lock Chats:** Hidden chats not secure enough? Lock individual chats which only open after YOU have authorized it.



**End Conversations:** Once you're done with a conversation, you can choose to end it, by swiping your friend's message from left to right. Doing so will delete all the conversation up until that message. 



**Save messages:** Double tap on any message to save it locally. Saved messages can be viewed by swiping right to left on the chat screen.



**No pesky notifications:** We do not believe in keeping users addicted to our app by frequent notifications. Chat when you feel like it. We do not bother you with notifications.



**No forwarding:** Enigma is developed to be an intimate one-to-one chat application. There's no option for forwarding messages. Hence no fake news.



**Beautiful, minimal UI:** The UI is uncluttered and beautiful. Gestures are used to make it pragmatic instead of using additional screen space.



**Less than 10 MB:** All the above features are tucked under a measely < 10 MB APK Size.
