This PR introduces the storage and retrieval of bookings.
### Server implementation
- New booking routes:
- GET `/booking`: Obtain the list ofer user bookings
- GET `/booking/{id}`: Obtain the specific booking object
- POST `/booking`: Creates a new booking
- The `BookingApiModel` objects are incomplete, the `Destination` is a
reference, not the full object, and the `Activity` list are also listed
as references only.
- Server booking always has an existing booking created (Alaska, North
America) for demo purposes.
- Storage is "in memory", stopping the server deletes all stored
bookings.
### New `BookingRepository`
- New repository class.
- Both local and remote implementations.
- Converts the `BookingApiModel` into a complete `Booking` that the app
can use, or a `BookingSummary` that only contains the necessary
information for the home screen.
### New `LocalDataService`
- Service that loads hard-coded data or from assets.
### New `HomeScreen`
- Route path: `/`
- Loads and displays the list of created bookings from the
`BookingRepository`.
- Tap on a booking title opens the `BookingScreen`.
- Floating Action Button to create a new booking.
### Changes in `BookingScreen`
- Can be accessed at the end of creating a booking or from the home
screen when tapping a booking title.
- Two commands:
- `createBooking`: Takes the stored `ItineraryConfig` and creates a
booking, the booking is stored to the `BookingRepository` (locally or on
the server).
- `loadBooking`: Takes a booking ID and loads that existing booking from
the `BookingRepository`.
- Simplified navigation: Once at `BookingScreen`, user can only navigate
back to `HomeScreen`.
- Share button converted to `FloatingActionButton`
### Integration Tests
- Updated to use new home screen.
- Updated to cover opening an existing booking in tests.
### TODO Next
- Refactor the `compass_model` project and move data model classes to
`server` and `app`, then delete project.
- Implement some user information for the home screen (e.g. retrieve
user name and profile picture url)
