[Widgets] [Gallery] Add system URL Scheme to widget gallery

WidgetKit library was presented appeared on WWDC20, and since then there has been no way to bring users to the Widget Gallery, and this becomes a stumbling block for many developers, since we are not able to send our users to developed widgets

I suggest Apple add a custom URL scheme similar to that for system applications:

  • facetime://user@example.com
  • sms:1-111-111-0037

And this URL Scheme is up to Apple, but there is a few thoughts about it:

How the URL might look like:

widgetgallery:
widgetgallery:type=<...>&family=<...>

URL Scheme parameters:

  • type - widget's kind string identifier, defined in app
  • family - family of widget

This will help make widgets more common among users, as well as increase conversion in their additions. For this reason, the development of widgets will become an appropriate feature for companies
