<itemvalue="Whether this entry must be included in the tree even if there is a fully [opaque] entry above it. By default, if there is an entirely [opaque] entry over this one, then this one will not be included in the widget tree (in particular, stateful widgets within the overlay entry will not be instantiated). To ensure that your overlay entry is still built even if it is not visible, set [maintainState] to true. This is more expensive, so should be done with care. In particular, if widgets in an overlay entry with [maintainState] set to true repeatedly call [State.setState], the user's battery will be drained unnecessarily. This is used by the [Navigator] and [Route] objects to ensure that routes are kept around even when in the background, so that [Future]s promised from subsequent routes will be handled properly when they complete."/>

<itemvalue="Cancels this subscription. After this call, the subscription no longer receives events. The stream may need to shut down the source of events and clean up after the subscription is canceled. Returns a future that is completed once the stream has finished its cleanup. Typically, cleanup happens when the stream needs to release resources. For example, a stream might need to close an open file (as an asynchronous operation). If the listener wants to delete the file after having canceled the subscription, it must wait for the cleanup future to complete. If the cleanup throws, which it really shouldn't, the returned future completes with that error."/>

<itemvalue="Waits for multiple futures to complete and collects their results. Returns a future which will complete once all the provided futures have completed, either with their results, or with an error if any of the provided futures fail. The value of the returned future will be a list of all the values that were produced in the order that the futures are provided by iterating [futures]. If any future completes with an error, then the returned future completes with that error. If further futures also complete with errors, those errors are discarded. If `eagerError` is true, the returned future completes with an error immediately on the first error from one of the futures. Otherwise all futures must complete before the returned future is completed (still with the first error; the remaining errors are silently dropped). In the case of an error, [cleanUp] (if provided), is invoked on any non-null result of successful futures. This makes it possible to `cleanUp` resources that would otherwise be lost (since the returned future does not provide access to these values). The [cleanUp] function is unused if there is no error. The call to [cleanUp] should not throw. If it does, the error will be an uncaught asynchronous error. @pragma("vm:recognized", "other")"/>
