I am using react-navigation to navigate the screen in my react native app. I have one question, is it possible that when I close screen or unmount screen, the rendered content are kept and not destroyed. So the next time when I call the screen again, the rendered content should not be reloaded again. Or maybe there is another way to achieve this. Thanks a lot
You should try redux and get your states from your reducers.

I made a page with the same url all the time. I show my div by hiding and showing components, but no route. So, now I need the user can go back page using the back arrow of the explorer. Is there any possibility?
The back button of the browser change the window history :
https://developer.mozilla.org/fr/docs/Web/API/Window/history
So i don't think you can link the browser back btn to a javascript variable and prevent his effect on history
You can find on the net solution where people force history.forward() when back btn is pressed, you can change your variable here. But it's a bit dirty
How can I stop the browser back button using JavaScript?
So I have a really ask but the implementation is eluding me.
I want to simulate the completion of a task in the background in our product demo.
The User Journey :
Arrive at the home page
Click button on the home page -> Button goes into loading state (button replaced by loading animation)
We continue on with the demo and navigate away
We want to come back to the home page after "execution complete" .
Well how do we know if execution is complete ? Well that's where this delayed alert I'm trying to implement comes in. I'd like an alert to be sent out , regardless of what page I am on in the app after some x minutes/seconds of clicking that button.
Any ideas on how I would go about doing this ?
I am trying with redux-toolkit but so far it's only working on the page itself and
if I return to the page after navigating away.
This can be done in two ways,
elevate the state to the point which covers both home page and all the navigation pages, Use react context API to pass data and use useEffect hook to track task completion and do the need full.
Use native javascript to trigger custom event and add an event listner to it Read more about curtom events here
Although this is all just theory, I can help more after viewing the code.
i stuck with one case in React Native. I have this components:
This is my App file..where my set i want to start with WebViewScreen, i still did not set useState etc.
My Navigation component:
And my WebView component:
So i have one question. How i can use navigation in WebViewScreen, when this component is outside of NavigationContainer. Some people will tell to import WebViewScreen as Stack.Screen .. okey but in my site where i have inputs and after click keyboard should up on Android when i click input keyboard up, refresh and hide..I need to use navigation, because with changeNavigationState i want to handle when user click on Login button, to redirect to my Native Login Screen. Thanks in advance :)
Theres is NO way you can use any navigation method from react-native-navigation outside of their own provider (NavigationProvider). If you want to use navigation on your WebviewScreen, you HAVE TO place it in a stack screen. Besides from that, anything else would be BAD PRACTICE. If this answer is not enough pls explain why you can't place the WebviewScreen in your NavigationContainer cause this is the real problem then.
I am trying to implement a page where top part of page is static and bottom part keeps on changing. I was able to achieve this using react-native-modal. But the problem is the back arrow button which is always supposed to be on the top of page becomes inaccessible entire time. I want to access the button even when modal is active.
Any help will be really appreciated cause it's not available anywhere, I went through the entire react native and react-native-modal docs related to this
I am using DrawerNavigator from react-navigation with Redux for my React Native app (using Expo). My Home screen contains a map (using react-native-maps). From Home screen, I navigate to a new screen.
Whenever I click the Back button in this new screen to go back to Home screen: dispatch(NavigationActions.back(), the Home screen always re-render. Is there any way to go back without re-rendering my Home screen and keep all the states and props unchanged?
This is an open issue I think. Try using a stacknavigator inside the drawernavigator instead.
