value property
The value of a StreamSubscriptionNotifier is read-only
, it can only be
modified by the StreamSubscription.onData callback. Use this getter to
read the most recent value the StreamSubscription, that was used to
initialize this StreamSubscriptionNotifier, emitted.
Can only be read if hasValue is true
.
It is always safe
to read value in a listener.
