Methods
-
build(
) → ShieldState -
Initialize a
Notifier. -
confirm(
) → Future< void> -
Sign + broadcast the shield (the SECOND half) — consumes the one-shot token
by id, the SAME
sendpath a payment uses. A per-tx broadcast failure is DATA, not a throw, so it lands as "saved for retry"; a thrown typed error routes per classifyShieldSendFailure — once the spend started, only a kind singleStepSendErrorPrecedesPersistence accepts; anything else lands on ShieldOutcomeUnknown (R13). On a money-moving outcome the cold balance is invalidated so the transparent line updates promptly. -
listenSelf(
void listener(ShieldState? previous, ShieldState next), {void onError(Object error, StackTrace stackTrace)?}) → RemoveListener -
Listens to changes on the value exposed by this provider.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
prepare(
) → Future< void> -
Propose the shield (the FIRST half) — DETERMINISTIC, LOCAL (no keys/proofs/
network). On a shieldable balance → ShieldReady with the confirmable
numbers; on
null→ ShieldNothingToShield (below the threshold, honest no-op); on a typed failure → ShieldUnavailable. -
reset(
) → void - Reset to idle — called on sheet entry so a prior terminal result never lingers into a new shield. A NO-OP while a step is in flight ( review F1): re-opening the sheet mid-submit RE-ATTACHES to the running flow — clobbering the transient would make the identity guards swallow the landing outcome.
-
runBuild(
) → WhenComplete? -
Executes
Notifier.build.inherited -
toString(
) → String -
A string representation of this object.
inherited
-
updateShouldNotify(
ShieldState previous, ShieldState next) → bool -
A method invoked when the state exposed by this
Notifierchanges. It compares the previous and new value, and return whether listeners should be notified.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
