描述
Current Behavior
From the docs:
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_A });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_B });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_C });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_D });
then
navigation.navigate({ key: SCREEN_KEY_A }); // will go to screen A FROM screen D
It will unmount B, C and D. (btw I think this should be highlighted more in the docs)
What if I want to keep let's say D mounted? And when I navigate to D again, I want to reuse the same instance.
My use case is a webview that I want to keep mounted in the background.
I found an old question in stackoverflow, never answered https://stackoverflow.com/questions/41818857/keep-react-native-webview-mounted
Expected Behavior
- I want to have the option to keep a screen mounted and reuse the same instance when I navigate back to it.
