Show ContextMenu on long press on visual element in mobile platform

[bohdan-bats-bs]

Description

We can now attach a context menu to any visual element using a MenuFlyout control, but on mobile it doesn't work correctly. It should appear on long press on visual element.

Public API Changes

API is not changed.

Intended Use-Case

It is very important issue, because context menu is used very often and developers wait that it will work on mobile on long press. This functionality will help .NET MAUI become #1 platform.

Thanks for your suggestion! Honestly, personally I think this is just not a super common pattern in mobile and that's why it probably wasn't added as such.

I don't think we will be adding this anytime soon, instead, I would be interested to maybe add #12816 and #8675 so that you should be able to implement this on your own where needed.

I've added this to the backlog for now and lets see if more people will find this and leave their comments or emoji reactions.

This suggestion is also here.

I also don't understand how FlyoutBase.ContextFlyout works on mobile for now. When does it appear?

If you simply want a context menu attached to any visual element with long press, natively, you can use our library:

I agree its not super common, but we have added this to our entire application to add some nice sugar to it. Hoping that our users will in the furure find it useful because we can group functionality closer to the context (like cards). Its actually also made us do some rethinking with our designers to figure out what we mean by our features, as they suddenly have to come up with a word for a feature (due to context menus have to be words with icons) that maybe just was a icon before.

Heres an example from our app:
