Toast Notifications (Snackbars) are brief, temporary messages that appear at the edge of the screen to confirm actions or provide lightweight feedback. Auto-dismiss after 3-5 seconds. Non-blocking—users can continue working while toast is visible. Common for "Saved," "Copied," "Deleted" confirmations.
Use toasts for non-critical, transient feedback: action confirmations (saved, deleted, copied), success states, non-urgent warnings. Don't use for errors that require action, critical information, or long messages. Place at bottom or top of screen. Keep text short (1 line). Auto-dismiss or provide dismiss button. Don't stack too many toasts.
