FeedDescriptor class

An append-only stream of events — requests, queries, log lines.

The events themselves do not travel with this: they are already in the core's ring, on PanelDescriptor.feedChannel, with replay and lazy detail fetch for free. This says only how to read them.

Constructors

FeedDescriptor(String id, String label, {String? description, List<FieldDescriptor> fields = const [], String? durationKey, List<PluginAction> itemActions = const []})

Properties

description → String?

final

durationKey → String?

The payload key holding a duration in milliseconds, when the feed has one — what a waterfall measures.

final

fields → List<FieldDescriptor>

final

hashCode → int

The hash code for this object.

no setter, inherited

id → String

Unique within its panel.

final

itemActions → List<PluginAction>

Offered on one event rather than on the feed. The event's id is passed as event, so a handler can reach the details the ring is holding for it — which is how explain runs against the query the user clicked.

final

label → String

final

runtimeType → Type

A representation of the runtime type of the object.
