FakeSnapshotSource class

A fake SnapshotSource: a broadcast StreamController the test pushes through, plus a settable current (mirroring the real runtime's last-emitted accessor). push updates current AND emits, 1:1, like the change-gated runtime.

Constructors

FakeSnapshotSource([GraphSnapshot? _current])

Creates the fake source with an optional initial current.

Properties

current → GraphSnapshot?

The most recent snapshot, or null before the first baseline.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

snapshots → Stream<GraphSnapshot>

The work graph as it changes — change-gated, broadcast, non-replaying.

no setter, override

Methods

close() → Future<void>

Closes the stream (call from an addTearDown).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

push(GraphSnapshot snapshot) → void

Sets current and emits the snapshot to subscribers (after a microtask, like a real broadcast stream).

raiseError(Object error) → void

Emits an error on the stream WITHOUT touching current — a fake connection blip, so a consumer's absence-≠-deletion handling (tg-nsj D-Z3) can be proven without retracting the last known snapshot.

refreshQuietly(GraphSnapshot snapshot) → void

Sets current WITHOUT emitting — the change-gated runtime's QUIET refresh: a floor tick against an unchanged store advances current's capture time but publishes nothing (tg-zd4v freshness).

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
