React native container subpages navigation - react-native

I am creating a React native application with the following scenario:
There is a navigation bar at the bottom of the screen, allowing the user to navigate between three main pages. On one of these pages, there is a backdrop with a container overlayed on it with two buttons. Each of these buttons should show open different "pages" in that container, and the navigation bar will be hidden when the user opens one of those "pages". An image is included below.
App layout example
My question is: how is this best implemented in react native?
My original idea was to implement a custom Stack Navigator with createStackNavigator. While this does work, I was wondering if this is a good way to go about it.
One result from using a custom navigator is that the navigation state in the container is also bound to the back button of the device (on Android). However, this is a welcome feature in this case as it makes sense in the navigation flow.

React Native & React Navigation 5.x: hiding bottom tab bar in specific screens

I'm currently building an app that has a bottom tab bar with a navigation stack in each tab. Now I want to create an image screen where the tab bar is hidden. I've followed the docs at https://reactnavigation.org/docs/hiding-tabbar-in-screens, which works fine if you only want the user to able to navigate to the screen and then navigate back to the tab stack.
The problem is that I want it to feel like the image screen is part of the tab stack so the user can navigate from the image screen to another screen (i.e. push another screen on top of the stack). This doesn't work for me using the method mentioned above...
I've also tried using the option tabBarVisible: false, but it makes the "hide animation" glitchy (which the docs also warns for: https://reactnavigation.org/docs/bottom-tab-navigator).

Is there a way to hide a single tab bar item using React Native Router Flux?

I'm using React Native Router Flux and have a bottom tab bar. I have a screen set up with a lot of links to other screens on it. If the parent scene isn't added to the tabs, I'm unable to route to it.
I've looked through the documentation and tried various options and styling. I think the easiest option would be to apply a width of 0 to that particular scene group, but it isn't available with View styles.
I want to be able to hide the parent scene so it isn't showing in the tab bar. At the moment, nothing is changing and the item is showing in the tab bar.
Figured it out. The problem was that I had the child scenes nested within a parent scene. When I removed them from the parent and outside of the tabs, it worked perfectly.

React Navigation navigate and scroll

I'm using the StackNavigator from react-navigation and I'm trying to customize the navigation process.
On one screen, I have two buttons that both use the "navigate" function to redirect the user to the same screen (which is a scrollview). Is there any way to have one of the buttons scroll down to a different part of the screen after navigating?

Is there a special name for a toolbar like thing at the bottom of Instagram?

The attached Instagram snapshot has a collection of buttons like Home, Search, Add etc. at the very bottom. What is this component called? Is it called tab navigator? Any special name for it?
iOS calls this a Tab Bar, which appears at the bottom of an app screen and is used for navigation between an app's various functions.
It's not the same as a Toolbar, which appears at the bottom of an app screen and contains actions relevant to the current view.

How to access UINavigationController in react native?

I have created a View where the NavigationBar comes from Obj-c(Native code) and the rest of the view comes from React Native.
Now in the react native view, i have a link which should show the content in a new screen with the navigation experience. I am able to show the content but unable to find a way to change navBar title and show back button on the navBar.
Can you please let me know how we can get access to NavigationBar(Obj-c) in ReactNative?
I don't believe React Native supports this. You cannot take an object created in one language and access it in another. It would be a better idea to create your navigation bar in your JS and use it throughout your app. That even allows you to propagate that UI to your android apps.
