Hey there! Just wanted to let you know that this repo is currently my personal side project to build something cool while learning about Dart and Flutter.

Contributions to this project are always welcomed, and in fact, even strongly encouraged here! Since I am only able to work on this during my spare time, any contributions from the community is valuable. If you are a developer, feel free to tackle any issues present.

Your passion, contributions, and ideas would be greatly appreciated! Together, let's make this project shine. 🚀 💻

Contributing

Contributions are always welcome, but please abide by our community code of conduct!

To contribute potential features or bug-fixes:

1. Fork this repository, and clone with submodules: git clone --recurse-submodules -j8 git@github.com:thunder-app/thunder.git
2. Base the feature or fix off the develop branch. This is to allow for pre-release versions without affecting the main general releases.
3. Apply any changes and/or additions based off an existing issue (or create a new issue for the feature/fix you are working on)
4. Create a pull request to have your changes reviewed and merged

Building From Source

Installing Flutter and Related Dependencies

Thunder is developed with Flutter, and is built to support both iOS and Android. There may be unofficial support on other platforms but is not guaranteed at this time (Linux, Windows, MacOS)

To build the app from source, a few steps are required.

1. Set up and install Flutter. For more information, visit https://docs.flutter.dev/get-started/install.
2. Ensure that you are on Flutter's stable channel using flutter channel stable.
3. Clone this repository and fetch the dependencies using flutter pub get
4. Run flutter gen-l10n to generate the localization files.
5. Optional: Run the build script using dart scripts/build.dart, which will build both the iOS and Android release versions. This step is only required if you want to build a release version of the app.

Building with Docker

Alternatively, you can skip the prerequisite setup and build the Android application via docker with a single command:

./scripts/docker-build-android.sh

Developing with Docker

You can also run your local development environment for Android via the Docker container, including connecting to ADB on the host machine.

./scripts/docker-dev-android.sh

Troubleshooting

Could not determine the dependencies of task ':unifiedpush_android:compileReleaseKotlin'.
> Cannot find a Java installation on your machine matching this tasks requirements: {languageVersion=8, vendor=any, implementation=vendor-specific}
   > No locally installed toolchains match and toolchain download repositories have not been configured.

Resolution: Ensure you have a valid Java 8 installation on your machine.

Conventions

While there are no specific conventions that must be followed, do try to follow best practices whenever possible.

Suggestions are always welcome to improve the code quality and architecture of the app!
