To which category do Flow type streams in programming belong?

Flow type streams in programming belong to the category of reactive programming and asynchronous data streams. In Android and Kotlin, Flow represents a sequence of values that can be computed asynchronously and processed as they arrive.

Flow allows working with data streams that can be generated with delay, such as data from the network, database, or user input, and supports operators for transforming, filtering, and combining these data.

Thus, Flow is an abstraction for an asynchronous, reactive, and lazy data stream.
