I've used Google Maps in a native Android app, and used a similar map view in an iOS native app, and I've integrated a couple of plugins into a Gideros app. I've never created a Gideros plugin.
That said, how monumental a task would it be to create a mapping plugin? Has anyone explored it? I'd want a screen that would allow users to zoom and pan, show crosshairs or some other marker of a selected position, and maybe overlay icons at selected coordinates. I'm considering developing this plugin, and I'm trying to get a sense for how much work I may be looking at.
I see others have asked about such a plugin, and I'm contemplating trying to create it. Has anyone else considered creating such a plugin?
I'd be interested to hear from anyone who's worked on custom plugins, but especially those with a common interface between Android and iOS. Any thoughts?
