A Dialog widget component.

Dialog Reveal Snippet

A dialog built the way recorder-style tools do it: a secondary

Shell is created and opened first, and its content is built in a later

event-loop iteration. The content payload then travels on the Shell's own

channel while the Flutter side is still mounting it from the Display embed —

exactly the buffered-payload window that used to leave the dialog empty.
