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

5. Building

When building Commet, there are some additional command line arguments that must be used to configure the build.

PLATFORM	'desktop', 'mobile', 'linux', 'windows', 'macos', 'android', 'ios', 'web'	Defines which platform to build for
BUILD_MODE	'release', 'debug'	When building with 'debug' flag, additional debug information will be shown

Optional

GIT_HASH	*	Supply the current git hash when building to show in info screen
VERSION_TAG	*	Supply the current build version, to display app version
BUILD_DETAIL	*	Can provide additional detail about the current build, for example if it was being built for Flatpak or Snap
