This PR introduces: - A new feature for Activities (UI unfinished). - A repository for the current Itinerary Configuration. - A `Command` utils class to be used in View Models. **Activities** - PR adds the `compass_app/app/assets/activities.json` (large file!) - Created `ActivityRepository` with local and remote implementation. - Added `getActivitiesByDestination` to `ApiClient` - Added `Activity` data model - Created `ActivitiesScreen` and `ActivitiesViewModel`. - WIP: Decided to finish the UI later due to the size the PR was taking. - WIP: Server implementation for Activities will be completed in another PR. **Itinerary Configuration** - Created the `ItineraryConfigRepository` with an "in-memory" implementation. (local database or shared preferences could potentially be implemented too) - Refactored the way screens share data, instead of passing data using the navigator query parameters, the screens store the state (the itinerary configuration) in this repository, and load it when the screen is opened. - This allows to navigate between screens, back and forth, and keep the selection of data the user made. **Commands** - To handle button taps and other running actions. - Encapsulates an action, exposes the running state (to show progress indicators), and ensures that the action cannot execute if it is already running (to avoid multiple taps on buttons). - Two implementations included, one without arguments `Command0`, and one that supports a single argument `Command1`. - Commands also provide an `onComplete` callback, in case the UI needs to do something when the action finished running (e.g. navigate). - Tests are included. **TODO in further PRs** - Finish the Activities UI and continue implementing the app flow. - Introduce an error handling solution. - Move the data jsons into a common folder (maybe a package?) so they can be shared between app and server and don't duplicate files. **Screencast** As it can be observed, the state of the screen is recovered from the stored "itinerary config". Note: Activites screen appears empty, the list is just printed on terminal at the moment.

Miguel Beltran	be0b3dc0d1	Compass App: Add "server" dart shelf-app and "shared" dart package (#2359) ... This PR introduces two new subprojects: - `compass_server` under `compass_app/server`. - `compass_model` under `compass_app/model`. **`compass_server`** - Dart server implemented using `shelf`. - Created with the `dart create -t server-shelf` template. - Implements two REST endpoints: - `GET /continent`: Returns the list of `Continent` as JSON. - `GET /destination`: Returns the list of `Destination` as JSON. - Generated Docker files have been removed. - Implemented tests. - TODO: Implement some basic auth. **`compass_model`** - Dart package to share data model classes between the `server` and `app`. - Contains the data model classes (`Continent`, `Destination`). - Generated JSON from/To methods and data classes using `freezed`. - The sole purpose of this package is to host the data model. Other shared code should go in a different package. **Other changes** - Created an API Client to connect to the local dart server. - Created "remote" repositories, which also implement a basic in-memory caching strategy. - Created two dependency configurations, one with local repositories and one with remote repos. - Created two application main targets to select configuration: - `lib/main_development.dart` which starts the app with the "local" data configuration. - `lib/main_staging.dart` which starts the app with the "remove" (local dart server) configuration. - `lib/main.dart` still works as default entry point. - Implemented tests for remote repositories. ## Pre-launch Checklist - [x] I read the [Flutter Style Guide] _recently_, and have followed its advice. - [x] I signed the [CLA]. - [x] I read the [Contributors Guide]. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] All existing and new tests are passing.
