# timeout method

Future<T> timeout (Duration timeLimit, { FutureOr<T> onTimeout() })

Time-out the future computation after `timeLimit` has passed.

Returns a new future that completes with the same value as this future, if this future completes in time.

If this future does not complete before `timeLimit` has passed, the `onTimeout` action is executed instead, and its result (whether it returns or throws) is used as the result of the returned future. The `onTimeout` function must return a `T` or a `Future<T>`.

If `onTimeout` is omitted, a timeout will cause the returned future to complete with a TimeoutException.

## Implementation

    Future<T> timeout(Duration timeLimit, {FutureOr<T> onTimeout()});
