[FIXED] What is the hot flow and cold flow in coroutines and the difference between them?

Issue

I am mastering Kotlin coroutines and trying to figure out

1- what is hot flow and cold flow ?

2- what is the main difference between them?

3- when to use each one?

Solution

A cold stream does not start producing values until one starts to collect them. A hot stream on the other hand starts producing values immediately.

I would recommend to read below to understand hot and cold steams with usage:
