api/discovery_tip library

Classes

DiscoveryContext: Context passed to a tip's eligibility check and its presentation.
DiscoveryPresentation: Renders a tip. Subclass for a new presentation style, or use the built-in ModalPresentation / InlinePresentation escape hatches.
DiscoveryTip<E extends Object>: A single feature-discovery entry. Parameterized on E — the consumer- defined event type (typically an enum) used to match triggers.
InlinePresentation: Escape hatch for tips whose presentation is already implemented elsewhere (e.g. an existing showMyCustomSheet function). The run callback is responsible for rendering and returning true when something was shown.
ModalPresentation: Renders a modal dialog via showDialog. The build callback receives the dialog's BuildContext and the emitting DiscoveryContext so the modal body can read ctx.data, close itself, etc.

DiscoveryPriority: Lower value == evaluated first when multiple tips match the same event.
