[Request]: (share_plus) Add platform exclusion functionality for iOS.

[StanleyCocos]

Plugin

share_plus

Use case

I noticed that share_plus indeed lacks platform exclusion functionality for iOS. Specifically, this feature is outlined in Apple's documentation. Currently, the plugin does not support this feature, but I believe it's quite useful. I also saw that some developers suggested this feature with fix messages like issus: (https://github.com/fluttercommunity/plus_plugins/issues/3075), but unfortunately, it hasn't been added yet.

Proposal

I hope this feature can be added. I have submitted a request.
