FakeAsync class
A class that mocks out the passage of time within a Zone.
Test code can be passed as a callback to run, which causes it to be run in a Zone which fakes timer and microtask creation, such that they are run during calls to elapse which simulates the asynchronous passage of time.
The synchronous passage of time (as from blocking or expensive calls) can also be simulated using elapseBlocking.

Methods
-
elapse(
Duration duration) → void - Simulates the asynchronous passage of time.
-
elapseBlocking(
Duration duration) → void - Simulates the synchronous passage of time, resulting from blocking or expensive calls.
-
flushMicrotasks(
) → void - Runs all pending microtasks scheduled within a call to run or fakeAsync until there are no more microtasks scheduled.
-
flushTimers(
{Duration timeout = const Duration(hours: 1), bool flushPeriodicTimers = true}) → void - Elapses time until there are no more active timers.
-
getClock(
DateTime initialTime) → Clock - Returns a fake Clock whose time can is elapsed by calls to elapse and elapseBlocking.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
run<
T> (T callback(FakeAsync self)) → T -
Runs
callback
in a Zone where all asynchrony is controlled bythis
. -
toString(
) → String -
A string representation of this object.
