Empowering secure, decentralized communication worldwide

• Desktop clients meet parity with mobile.
• Screen lock and pin protected cache features.
• P2P messaging through a locally run server on the client.
• Allow transfering user data from one homeserver to another, or from local to remote servers.
• CLI client using ncurses and the same redux store contained here (common).

You may notice Katya ® 👽 does not look very dart-y (for example, no _private variable declarations, or using redux instead of provider) in an effort to reduce the learning curve from other languages or platforms.

• Workstation independent setup for Katya ® 👽 development:
  • Install Flutter (stable channel for all platforms);
  • Install necessary third party SDKs and tooling:
    • iOS -> XCode;
    • Android -> Android Studio;
  • Install CMake from CLI through Android Studio Platform Tools (for OLM/megOLM);
  • Install libs needed for CMake:
    • Mac OS -> brew install ninja;
    • Linux -> sudo apt install ninja-build;
    • Windows -> choco install ninja;
  • Clone repo and init submodules:
    • git submodule update --init --recursive;
  • Run the following prebuild commands:
    • flutter pub get;
    • flutter pub run build_runner build;

0. Install Android Studio;
1. Install latest Commandline Tools through Android Studio GUI;
2. Confirm sdkmanager is available in your path;
3. Pull the latest CMake, NDK, and other dependencies;
4. Pull dependencies needed:

• flutter pub get;

1. Generate JSON conversion for models:

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

2. Generate JSON conversion for models:

• flutter run.

1. flutter config --enable-macos-desktop;
2. brew install libolm to install native OLM dependencies;
3. Copy the dylib - not the soft links - to the macos folder:

• cp /opt/homebrew/Cellar/libolm/libolm.3.x.x.dylib ./macos/libolm.3.x.x.dylib;

3. Follow instructions for linking the dylib generated from brew to the Katya ® 👽 project:

• Refer to Mac OS dylib linking guide;

4. flutter build macos to build the .app bundle.

1. flutter config --enable-linux-desktop;
2. apt install libolm3 libsqlite3-dev or pacman -S libolm or platform equivalent for libolm;
3. flutter build linux && flutter build bundle;
4. Navigate to release at ${Katya ® 👽_ROOT}/build/linux/release/bundle;
5. Confirm build works with running ${Katya ® 👽_ROOT}/build/linux/release/bundle/katya.

1. flutter doctor should give you warnings for anything missing;
2. flutter config --enable-windows-desktop;
3. Compile OLM & move olm.dll to libolm.dll in the executable directory;
4. Fetch SQLite's Precompiled Binaries for Windows dll from the website.

• Views (Flutter + MVVM);
• State Management (redux);
• Cache (redux_persist + json_serializable + sembast + codec cipher);
• Storage (drift + sqflite + sqlcipher).

• Notifications:
  • Utitlizes android_alarm_manager on Android to run the sync requests in a background thread and display notifications with flutter_local_notifications;
  • No third party notification provider will ever be used outside Apple's APN'S for iOS only.
• Equatable:
  • This library allows comparisons of objects within Flutter to tell if they have changed.
• JsonSerializable:
  • Unfortunately, JSON is not integrated directly in Dart/Flutter for your own objects. Code generation is required, for now, and will convert Katya ® 👽's custom objects to a 'Map' of respective JSON fields.
• Freezed (future):
  • Because every object in Katya ® 👽 is immutable, freezed will help create objects doing the same thing all the 'copyWith' helper functions do today, with the improvement of allowing 'null' values to overwrite non-null values.
