I have a Stack Navigator where screen A pushes to screen B.
I would like to preload screen B so there is no lag when pushing from screen A. How can I do that?
I've seen there is a lazy: false option for bottom tab navigators, is there something similar for Stack Navigators?
There isn't a way to do this in a Stack Navigator from what I understood by the Github Issue #6010.
In drawer/tabs, there are a fixed number of all screens, so all of
them can be rendered and you just navigate to an existing screen. The
order in which the screens are rendered is also fixed.
It doesn't make sense for stack. There's no limit to how many screens
that can be rendered and there's no guarantee about order of screens
or what is the next screen. There can also be multiple instances of
the same screen.
The navigation state for stack is populated you push a new screen as
opposed to drawer it tabs where there state already includes all
screens.
I found the above after I read the Github Issue "How to mount all screens on App load".

I am using react-navigation (v6.x) in a react-native app.
I have a drawer navigator setup which holds different stack navigators.
If I hide the drawer's header, the drawer button gets hidden and it won't be obvious to the app users that the drawer is there.
If I hide the stack screen's header (inside the stack navigator) it hides the back button and the users won't be able to go back unless they're using the hardware button(Android)/gestures (iOS).
How can I achieve the following:
1- Hide the Stack screen's header, and show the drawer's header on the first screen of the stack (reveal the drawer button, since the back button is not needed at this stage).
2- Hide the drawer's header and show the stack screens header on the second screen of the stack (hide the drawer button, reveal the back button so the user can go to the previous screen in the stack)
or is there a cleaner approach?
Thanks!
ive got a react navigation structure like so
Home
--RestaurantList
--RestaurantDetails
My Queues
Home and My Queues are within a Tab navigator. RestaurantList and RestaurantDetails are within Home's Stack navigator.
Navigating from RestaurantList to RestaurantDetails gives a slide-in animation because it is navigating from a stack to another stack screen as seen.

I want that same slide in animation for navigating from my My Queues to RestaurantDetails, from a tab screen to a stack screen. It is currently just instant with no animation as seen.

How can I achieve the same slide-in animation when navigating from MyQueues to RestaurantDetails?
I'm making an app, and in the app there is a home screen. On the home screen, I want to add a bottom navigator with various logos, which when clicked on, navigate the user to a different screen. I only want the bottom navigator to be on the screens that can be accessed from the bottom navigator in home. How would I do this? Would I need different types of navigators in my app.js since I'm using a stack navigator as well? Thanks for any help, I sincerely appreciate it.
Use tab-based-navigation provided by react-navigation. Make tab navigator with the screens that you want to be displayed with tab and wrap that in Stack. Any other screen that you want to display without tab navigation, just add as another stack and wrap all the stacks in Stack.Navigator. Here's the docs they are pretty well explained

I have a DrawerNavigator with a list of screens. The problem is that if I go to another screen and come back, the first screen re-initializes completely. How to prevent this re-initialization so that whatever the state of the first screen was, is preserved on coming back?
I've created a Snack for this: https://snack.expo.io/HJebCIoiM
The problem is really simple, but most issues I've found on GH and SO are about the opposite behaviour: resetting the StackNavigator to its initial route when switching between items in the DrawerNavigator.
App structure
Drawer
Router
First screen
Second screen
Other screen
The initial route is Router, which by default shows the first screen.
Current behaviour
I go from the first screen to the second screen
I toggle the drawer
I go to the other screen in the drawer
I go back to the Router
It shows the first screen
Expected behaviour:
In step 5. it should show the second screen, because that's the last route I was on when I toggled the DrawerNavigator.
I don't understand why it doesn't preserve the state of the stack, and just takes me back to the screen I was on before, but instead resets the stack to its initial route.
What confuses me even more is that many people are reporting that this is the default behaviour of their app, but they do want to reset the stack and are struggling with this:
Resetting the navigation stack for the home screen (React Navigation and React Native)
Clear stack being navigated to React-Navigation
How to reset the state of a StackNavigator nested in a DrawerNavigatior?
I don't understand why it does reset it all the time in my case. (and as you should be able to reproduce with the Snack I posted above.
