Is there a way to do async computations before the app is finished loading?

I want to get some data from the localstorage on the device before the first screen starts rendering. I already have the functionality in place, but my question is as follows: Is there a way to execute code before React Native shows the first screen?

Right now I have added an extra screen that does these computations, when it is done, it will redirect to the "Home" page. However I would like to eliminate this launch screen altogether.

Right now, I have it implemented like this:

APP LAUNCH -> go to startup screen -> do some async computations -> once finished, go to home page.

The expected result would look something like this.

APP LAUNCH -> do some async computations -> once finished, go to home page.

If you are using the react-navigation so you can use the switch navigator
