White screen shows after Splash Screen in React Native - react-native

in React Native, a white screen appears after the Splash Screen. The white screen is briefly displayed, and then the application screen opens. What is the reason for this? I want to solve this problem without using a package. How can I solve this problem?
I don't understand what kind of mental illness the detractors are. Most solutions are out of date and use packages!

Is there a way to have a screen with snap points(presentation: "modal") in react native navigation?

I want to have a scrollable (with snap points) react native navigation stack screen(presentation: "modal") in my app. I don't want anything like "react-native-modal" library or official Modal from react native library. I want an actual screen with modal behaviour and I can achieve that with presentation: "modal" property but I want it to have snap points. Perfect example would be the iOS fitness app.
So this is the screen when you initially press upload button. As you can see it takes maybe 40% - 50% height of the screen
If you scroll down height expands and it acts as ordinary screen with presentation: "modal"
And lastly if you scroll back up it springs back to its original position and it acts as a modal(no gap at the top of the screen as in second image)
That is the behaviour I am looking for.
If it is possible I would like to get similar behaviour on android as well.
I tried to implement that behaviour with "react-native-modal" and official Modal from "react-native" components but I want to have it as a separate screen. I also want it to feel "native like" and with these stuff it doesn't feel that way.

React Navigation Stack Navigator does not update ui on iOS

When screen height changes (In the case of my project because a custom bottom tab is removed for certain screens), the Stack Navigator height does not update to occupy the entire screen anymore for some reason.
The same scenario works just fine on Android and on the Web for some reason, on iOS, when a view that was occupying some portion of the screen is removed after the stack screen was already being rendered, the Stack does not change its height.
Please take a look at this minimal expo snack example that demonstrates the issue and compare going to the 2nd screen on iOS emulator versus going to the 2nd screen on Android for example.
Expo Snack
Adding a key={currentScreenName} to Stack.Navigator fixes the issue but that is not really a viable solution since it will cause a re-render and the screen will flicker when transitioning between the pages.
I know that using a bottom tab this way is not really ideal but I was wondering if someone might have any good suggestions as to how this can be addressed.
Thank you.
Quick note, this seems to be working just fine with #react-navigation/stack but not with #react-navigation/native-stack

How to remove white flashes on react-native app on Android?

When my app is launching I can see a brief white flash when screens are changing. I have a dark theme app so it's pretty annoying to see those flashes.
I have found react-native-flash-screen module which could help me (install, link, edit MainActivity.java, import to App.js) but after installing of it my app goes to loop of rebooting.
Does someone know how to prevent white flashes, probably, on another way?
it's hard question because I have not seen your code
but
wrap your app container with a view and style that backgroundColor to black
this might help your

What is the best way to recreate the Google Spaces navbar in a React Native app?

The Google Spaces app had a raised bump in its bottom navigation. I kinda liked the look but I'm not sure how best to recreate it using React Native.
I'm assuming it would be something like adding an image above the navbar to show the bump but that doesn't seem right since the actual button in the navbar wouldn't extend into the curved area.
Here's a link to an image of the navbar in question:
