The kotlin flow is one of the types like thread mechanisms; it is mainly due to the flow of data that can safely make the network request for to produce the next value without blocking the main programming thread. These operators are functions that, when takeWhile() and skipWhile() Another variant of the take() operator is the takeWhile() operator, which takes emissions while a condition derived from each emission is true. But what if you go further and apply it everywhere, literally everywhere, including View layer?. "$number$letter". What's different in 2.0 - RxJava Doc.
