React Native duplicate screen error

For my own case study, the screen duplicated is the "Message" screen. Follow the texts marked with red

And the source is the BottomTabNavigation. Follow the text marked with blue.

This is the same approach to understanding the errors you find, just read the error messages a little more, and this is the case with a ton of other errors.

2 What is this error saying?

Simply, that a particular screen is created twice in the navigation.

3 Investigating

search through your root cause, for me, you've guessed it right, the BottomTabNavigation component.
