A simple command-line application with an entrypoint in bin/, library code in lib/, and example unit test in test/. The app is a very basic card game.

1. Install dart from https://dart.dev/get-dart
2. Navigate to the project's folder
3. Install dependencies running this command:

dart pub get

After the setup you can start the app simply by running

dart ./bin/main.dart

from the project's folder

App has just a couple of simple unit tests for a game model To start tests simply run

dart test

Game model is the only one with tests, but it's still not fully tested, a logic to handle cases like calling play() multiple times or dealing cards are not handled gracefully etc. But I believe it's not the point of this exercise to make full-blown tests and to make this simple app perfect or to waste time trying to ;)
