What does the withContext(Dispatchers.IO) function does?

#1

what is the meaning of the arguement Dispatcher.io and what is the withContext Function doing. i Have a confusion in it. Please help me out

#2

withContext function is used to switch context.

Networking, Databases, reading or writing files are done inside the Dispatchers.io

Consider a coroutine or a function where you need to do a network request and update the UI within the coroutine. first you do the network request inside the Dispathers.io context and for the code where you need to update the UI you use.

withContext(Dispatchers.Main){ //update ui }

Here Dispatchers.Main is used to execute the code in the Main thread.
Let me know if this resolves your confusion
