"Design Choices"

• State Management: bloc + setState (the latter in some rare cases)
• Dependency Injection: get_it
• Architecture: Layered (not perfectly)
• DB: None
• Auth Service: None
• Device Integrity: AppCheck (I'm considering replacing it with freerasp)
• Translation Tool: Inlang
• Env Var management: (TODO: Envied)

Getting Started

A guide on how to get started with everything.

Required tooling

The following things are required to get started:

• Flutter sdk (see below to get it)
• Android Studio & XCode (if MacOS)
• A code editor (e.g. VSCode, JetBrains, Sublime, Vim) etc.
• The backend repository

Let's Go

1. Setup backend by following the README
2. Install dependencies via: flutter pub get
3. A firebase account with a project and appcheck enabled
4. Create a .env file as seen below
5. Checkout the CONTRIBUTING file
6. Either you setup firebase appcheck with this project or comment out the code related to that while debugging AppCheck.dart
7. Replace the public key with the one generated in the backend
8. You are good to go just use: flutter run to run the app

Testing

The tests folder structure is the same as the one under lib. If you create new tests place them accordingly. All files needs to end in **_test.dart the _test part is important!

Integration tests need to be placed under integration_test folder ! And are run via flutter test integraton_test.

Running tests

• Run: flutter test in your console and you should be good to go

.env

Point these to your urls
