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. 🚀 💻

Releases

Android

If you are on Android, releases are available in the Releases section under the corresponding version. There is also an option to obtain the release through IzzyOnDroid if you are interested.

iOS

If you are on iOS, there is TestFlight available through this link. An alternative is to download the corresponding IPA file in the Releases section and install it through AltStore.

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 limited 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.
  2. Clone this repository and fetch the dependencies using flutter pub get
  3. Generate an empty .env file. The .env file holds any credentials. At the time of writing, en empty .env file with a comment is all that is required.
  4. Run the build script using dart scripts/build.dart, which will build both the iOS and Android release versions

Environment File

This is an example of the .env that can be used for Thunder.

SENTRY_DSN=""

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!
