Future<T>.microtask constructor
- FutureOr<
T> computation(
Creates a future containing the result of calling computation
asynchronously with scheduleMicrotask.
If executing computation
throws,
the returned future is completed with the thrown error.
If calling computation
returns a Future, completion of
the created future will wait until the returned future completes,
and will then complete with the same result.
If calling computation
returns a non-future value,
the returned future is completed with that value.
Implementation
factory Future.microtask(FutureOr<T> computation()) {
_Future<T> result = new _Future<T>();
scheduleMicrotask(() {
try {
result._complete(computation());
} catch (e, s) {
_completeWithErrorCallback(result, e, s);
}
});
return result;
}
