compass_app

The Compass sample application is an app that helps users build and book itineraries for trips. It’s a robust sample application with many features, routes, and screens. The app communicates with an HTTP server, has development and production environments, brand-specific styling, and high test coverage. In these ways and more, it simulates a real-world, feature rich Flutter application.

The code in this application is used for explaining architecture in a Flutter application.

The Compass app was originally designed and built by the Firebase GenKit team.

Running the app

This app contains multiple environments.

• Development environment - This environment uses data from a JSON file, which is stored in the assets directory, and simulates developing locally.

$ cd app
$ flutter run --target lib/main_development.dart

• Staging environment - This environment uses an HTTP server to get data, simulating a real app experience. This is a "dummy" server, that has endpoints that simply return fake data. The server can be found in the compass_app/server directory. You need to run the server locally before running the Flutter application.

$ cd server
$ dart run
# => Server listening on port 8080
 
$ cd ../compass_app/app
$ flutter run --target lib/main_staging.dart 

Integration Tests

Integration tests must be run from the app directory.

Integration tests with local data

cd app
$ flutter test integration_test/app_local_data_test.dart

Integration tests with background server and remote data

cd app
$ flutter test integration_test/app_server_data_test.dart

Running the tests together with flutter test integration_test will fail. See: flutter/flutter#101031
