Add iOS native design #30
Description
The current design is mainly based on Material Design 3. This follows best practices from Google/Android. However on iOS it makes sense to provide a more native feel by following Apples Human Interface Guidelines.
Flutter implements this with the Cupertino widgets. However we need more tooling for a decent integration.
One useful package is flutter_platform_widgets. This packages allows us to easily apply different theming without constant checks of the platform. Also it provide common widget that translates elements automatically into the "native" widget.
Another useful package is super_cupertino_navigation_bar, which provide a better navigation bar then the Cupertino one that's provided by default.
We might require further packages, since the provided Cupertino widgets are just ok-ish compared to using the native elements
