Xamarin - control that allows you to select from icons by swiping like iOS photo edit tools

I'm trying to find a control for Xamarin that allows you to pick a tool from a list of icons, but in a swipe format like in the iOS photo edit tools (image below).
I tried using CarouselView, but that only displays one item per swipe, and each item before and after - however I'd like around 5+ icons on screen, with the middle one selected.
If there isn't a control, I'll have to build one myself, but would prefer to use something that's already available if possible.
Thanks for any direction!
Oliver.
For me, the best practise for your case is to use the swipe gesture

and write an expandable animation like this sample

Icons have poor clarity in Xamarin forms UWP project

I am using 24x24 pixels icons in my xamarin forms UWP project, but not getting good clarity when it comes in UI. For Android, I am using 4 set of icons for different devices and 3 set for IOS. How many sets of icons are needed for UWP and what is the resolution for those icons?

Every app has an icon/logo that represents it, and that icon appears in multiple locations in the Windows shell:
The title bar of your app window
The app list in the start menu
The taskbar and task manager
Your app's tiles
Your app's splash screen
In the Microsoft Store
We have detailed article that specifically for icons that represent the app itself. please check this link and use the suitable size icon.

xamarin multiple image picker error - ELCImagePicker not working for second time

I am developing xamarin.forms PCL app.
I want to select multiple images from gallery so for ios I use ELCImagePicker.
Everything works fine when I open gallery for first time. But when I open it for second time(for e.g. changing selected image), app crashes. I use messaging center to pass my list of image paths to PCL project.
At second time, I receive messages multiple times and then I get FATAL SIGSEV error.
I have referred this link. And it has been very useful to people when I searched related multiple image picker on google.
Why is this happening ? Please help

How to get Google Street View / Virtual Tour to display as sphere in mobile web browsers?

Is it possible to get Google street view/google business view virtual tours to display as a sphere instead of a flat image ( or equirectangular I believe is the correct name) using the google maps api or embed? So far in my trials I have not been able to get it to display correctly. It just displays as a flat image (equirectangular) when on a mobile device.
The tour I have shown below is this one (just a random one I found): https://www.tourmake.it/nl/tour/e2f74fe593a99a3db61e921b417afbee
Ones that I have found that work on iOS/Andriod (Note these are complex google made ones so I am assuming they have done some custom coding to make it work?):
- https://insideabbeyroad.withgoogle.com/en/all-access/studio-1/1060#x=&y=&z=
- https://nightwalk.withgoogle.com/en/panorama/218
iOS - Safari (Just displays flat image)
Android - Google Chrome ( Works 100% how I want)
Another note regarding this demo above. It works fine on Andriod Google chrome but not iOS Google Chrome...
Any tips on how to get this looking good on both iOS and Android browsers?
Looks like I had to add google.maps.streetViewViewer = 'photosphere'; before initializing the object. That uses the new beta streetview renderer.
