I'm interested in passing a geometry object with certain attributes to an exposed feature class for committed edits. Essentially, I want to manually create a new feature without the template pane or editor widget. The geometry and attributes are both pre-defined, and the user just needs to select one pair from a group and push an "Add to Geodatabase" button.
I'm reading through the documentation and I can't see a clear way to do this. I see that if I don't want the pane or widget, then I need to use a geometry service, but I don't see a "create feature" method, or something that accepts a geometry object or attributes.
