Development
Commet is built using Flutter, currently v3.24.4
This repo currently has a monorepo structure, containing two flutter projects: Commet and Tiamat. Commet is the main client, and Tiamat is a sort of wrapper around Material with some extra goodies, which is used to maintain a consistent style across the app. Tiamat may eventually be moved to its own repo, but for now it is maintained here for ease of development.
Building
1. Install Flutter
2. Install Libraries
Commet requires some additional libraries to be built
sudo apt-get install -y ninja-build libgtk-3-dev libolm3 libmpv-dev mpv ffmpeg libmimalloc-dev
3. Fetch Dependencies
You will need to change directory in to commet, then fetch dependencies
cd commet
flutter pub get
4. Code Generation
We make use of procedural code generation in some parts of commet. As a rule, generated code will not be checked in to git, and will need to be generated before building.
To run code generation, run the script within the commet
directory:
dart run scripts/codegen.dart
