What is differece between goBack() and pop() in router

[ibcylon]

The content is a same with title.

I know pop() can be used only pushed View, but I wonder the reason separate them.

would you explain the useCase it must use goBack or more make sense to use goBack than pop()?

Thank you for making flowStacks

Hi @ibcylon, thanks for your question. You're right that goBack will go back to the previous screen, regardless of whether the current screen was pushed or presented. And pop does the same thing, but in debug builds it will stop program execution if the current screen was presented rather than pushed. This might be useful if you want to get an early warning while developing that your assumptions about the navigation state are not correct.

So it's a matter of personal preference: if you want to verify your assumption that the current screen has been pushed, use pop; otherwise, use goBack as it's more flexible.
