* fix: 1815 - around context.mounted
The PR is about two related topics:
* Removing all the `ignore: use_build_context_synchronously`
* Replacing all the `State<StatefulWidget> widget` by `BuildContext context`, now that it's possible in flutter
* Update packages/smooth_app/lib/pages/onboarding/permissions_page.dart
* format fix
* App review in the "scan card"
* Add a keep alive to prevent many requests
* Add a missing call to super (for the KeepAlive mixin)
* Don't really understand what happened with this file 🤨
Impacted files:
* `consent_analytics_page.dart`: minor refactoring
* `country_selector.dart`: now using the preferences for initial country code; same UI as language selector
* `main.dart`: minor refactoring
* `next_button.dart`: minor refactoring
* `onboarding_flow_navigator.dart`: refactoring around `OnboardingPage`
* `permissions_page.dart`: minor refactoring
* `product_query.dart`: minor refactoring
* `user_preferences.dart`: minor refactoring
* `user_preferences_dev_mode.dart`: minor refactoring
* `user_preferences_page.dart`: minor UI fix (app bar title on 2 lines)
* `user_preferences_settings.dart`: added the "selected language" parameter; minor refactoring
* `welcome_page.dart`: fixed a visual overflow bug
* Make smooth_app a module (also called step 1)
Android impl is OK.
Still have to check for iOS and tests
* Fix scan sound not working
* Fix ci/pub_upgrade.sh issues
* Fix tests
* Some doc
* Fix build actions
* Fix iOS build
* Fix warnings
* Fix Flutter analyze
* Fix typo
* The CI needs at least one test
