I have the following React Native navigation architecture:
Im trying to set the styling on a button in my TabHeader component (see blue arrow) based on which Screen I am on. However in the props passed into it by TabNavigator, I am only seeing the Stack directly beneath it, in this scenario the HomeStack.
Is it possible to get the current Screen (Home) in TabNavigator even when it is 2 levels deep? (Core -> HomeStack -> Home)

You can only modify navigation options for a navigator from one of its screen components. This applies equally to navigators that are nested as screens.
On the same page there is a title Setting parent screen options based on child navigator's state

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
https://reactnavigation.org/docs/tab-based-navigation
Suppose I have 4 tab screens. The tab is created with a custom footer component with layout concept and all the navigational screens are listed in the stack navigator route section and used goBack() method to navigate the previous screen. now For a situation, my navigation route as follows started with
Home->Testimonial->offerings, then again from offerings->Testimonial->about here I stopped in this screen then pressed the back button with goBack() function. but this time goBack() routes me to
about->testimonial->offerings->home. Like the unique screens are listed in stack navigators routes, not the duplicate screens.
I want to know is it an issue? if yes, then how can I manage it?
Use a unique key for your screen.
https://reactnavigation.org/docs/navigation-actions/
navigation.navigate({
name: 'offerings',
key: 'offerings' + someUniqueId,
})
I am creating an app by React Native.
and I'm using React Navigation.
This is the current project.
but I want to open a modal from the bottom.
I want to hide the tab bar.
Please tell me how to do it.

Current project screen:
This is controllable via the order and nesting of navigation stacks.
You currently have a structure like this:
- BottomTabNavigator
- StackNavigator (with ModalPresentationIOS - ShopStack)
- Home
- ShopDetailStack
In order to hide the tabs behind the modal, you have to rearrange them:
- StackNavigator (with ModalPresentationIOS)
- BottomTabNavigator
- Stack Navigator (Shop Stack)
- Home
- ShopDetailStack
This basically means that your modal stack should contain the tab navigation, not the other way around. The detail screen (the screen from the modal) needs to be declared as a sibling to the tab navigator)
I am using react-native-navigtion and have 4 tabs. Tab 1 is the home screen, tabs 2-4 have a navigation stack in each. Tabs 2-4 are made up of a re-usable component so, there is no clear root component. When in the root screen of tabs 2-4, I want the android back button to take me to tab 1. I have found how to hook into the android back button, but I need to know if I am at the navigation root before sending a person to tab 1 (home).
Thanks in advance
I have a Parent SwitchNavigator which has two screens:
1. HomeScreen
2. DashBoard
Also my dashboard screen is actually a drawer Navigator that consists of other screens like:
1. Ongoing News
2. Profile Edit
3. Logout
Now in Logout If i write this.props.navigation.navigate("Home") it takes me to the Ongoing News screen which the home in this current child drawer navigator route... But I want to jump to the higher route i.e. the parent route of switch navigator and I want to go to the HomeScreen there instead of being in this route how can I achieve this??
I am beginner so please if you can explain in as simple words as possible that would be great... :)
