Part of the implementation of the Compass App for the Architecture
sample.
**Merge to `compass-app`**
This PR introduces the Search Form Screen, in which users can select a
region, a date range and the number of guests.
The feature is split in 5 different widgets, each one depending on the
`SearchFormViewModel`. The architecture follows the same patterns
implemented in the previous PR
https://github.com/flutter/samples/pull/2342
TODO later on:
- Error handling is yet not implemented, we need to introduce a "logger"
and a way to handle error responses.
- All repositories return local data, next steps include creating the
dart server app.
- The search query at the moment only takes the "continent" and not the
dates and number of guests, that would be implemented later on as well.
