Bottom Navigation issues

• Each time I go to events section, it is reloading
• Each time I go to Tickets section, it is reloading

This should not happen

@iamareebjamal @liveHarshit I have investigated this issue over the last 2 days. For my own knowledge now, it's clueless for me to fix this issue.

So basically the problem I found is that in the MainActivity, we set up the bottom navigation with navController:
setupWithNavController(navigation, navController)
From what I understand, everytime we click on a bottom navigation's icon, the navController will use the method navigate() to change the fragment in the container, and then clear(pop) all the fragment in the backstack. So if we use navigation with navController here, I don't find a way to keep all the old fragments.

I have tried to research on Singleton pattern to make each fragment a single instance, but I didn't find anything helpful. I also tried to save old fragments by using supportFragmentManager to save the fragment with tag but it made the code really complex and it would take a lot of time to refractor.

Please give some advices or correct me if something is not right

Please read comments in issue #1078. It is already discussed.

It was used earlier, but now we want to do it with navigation architecture component.
You can see the method in utils for check and load fragment. It is still there.
