Mix your bloc with the MultipleStreamMixin when mixed it has an override called streams
It's a Map<Object, StreamData<Object, Object>> where your can pass a unique key (any object, check the example directory for a detailed implementation) and a StreamData which has a field stream

stream has the return Type of Either<L,R>
where the L is considered as an error and the R is considered as a valid data
StreamData has 2 Type Parameters <L,R> these types will be used as the return type of the field stream
when ever a stream emits R of the either a function name onStreamData will be called which has 2 params one is the key which was given in the streams map in the override and the other is the data of the R;
onStreamError is called whenever the L of the either is called
