FlyoutCloseReason

The reason a flyout closed, carried on the esp-flyout-closed event detail.

• "escape" — the user pressed the Escape key
• "vellum" — the user clicked the overlay-mode backdrop
• "button" — the user clicked the flyout's close button
• "programmatic" — close() was called from code (including the "close-flyout" bus event)

type FlyoutCloseReason = "escape" | "vellum" | "button" | "programmatic"
