Methods
-
any(
bool test(CoapResponse element)) → Future< bool> -
Checks whether
test
accepts any element provided by this stream.inherited -
asBroadcastStream(
{void onListen(StreamSubscription< CoapResponse> subscription)?, void onCancel(StreamSubscription<CoapResponse> subscription)?}) → Stream<CoapResponse> -
Returns a multi-subscription stream that produces the same events as this.
inherited
-
asyncExpand<
E> (Stream< E> ? convert(CoapResponse event)) → Stream<E> -
Transforms each element into a sequence of asynchronous events.
inherited
-
asyncMap<
E> (FutureOr< E> convert(CoapResponse event)) → Stream<E> -
Creates a new stream with each data event of this stream asynchronously
mapped to a new event.
inherited
-
cancellation(
) → CoapRequest - Create a cancellation request
-
cast<
R> () → Stream< R> -
Adapt this stream to be a
Stream<R>
.inherited -
contains(
Object? needle) → Future< bool> -
Returns whether
needle
occurs in the elements provided by this stream.inherited -
distinct(
[bool equals(CoapResponse previous, CoapResponse next)?]) → Stream< CoapResponse> -
Skips data events if they are equal to the previous data event.
inherited
-
drain<
E> ([E? futureValue]) → Future< E> -
Discards all data on this stream, but signals when it is done or an error
occurred.
inherited
-
elementAt(
int index) → Future< CoapResponse> -
Returns the value of the
index
th data event of this stream.inherited -
every(
bool test(CoapResponse element)) → Future< bool> -
Checks whether
test
accepts all elements provided by this stream.inherited -
expand<
S> (Iterable< S> convert(CoapResponse element)) → Stream<S> -
Transforms each element of this stream into a sequence of elements.

inherited
-
lastWhere(
bool test(CoapResponse element), {CoapResponse orElse()?}) → Future< CoapResponse> -
