I was hitting this "bug" repeated times after upgrading RN > 0.50 Today I found out that this is due to the new error boundary handling in React 16. You can use componentDidCatch
in a root component of your app to handle these scenarios.
You can read more about it here:

I'm also having a similar problem problem. Regular errors are being caught correctly, but a TypeError in a render caused by a promise isn't caught and the red screen shows on both debug and release builds
from react-native-exception-handler.
Hmm. That's interesting @Kebabpizza . I ll take a look at that . But @andrew-wagner89 Red screen should never come in the release builds. .as they are entirely switched off during the build process.

Hi @Kebabpizza @andrew-wagner89 Can you guys help with a screenshot or a larger snippet? .. I am only getting a warning yellow screen after trying to replicate. And yellow screens dont cause a app crash.

Hi @master-atul, apologies for the late response.
After navigating to another screen with react-navigation, this produces a crash (red screen) instead of a yellow warning. And if you navigate within a promise react-native-exception-handler does not catch this.
Here is a sample: https://gist.github.com/Kebabpizza/925531ed9bab37ba6abf48f5de9c812a

im experiencing this too, which made me think it isnt working at all
from react-native-exception-handler.
It behaves bit peculiar for me. I tried the example given in the documentation of this plugin (like this.test() ).
I kept this code ( this.test() ) in one of the component life cycle methods, it didn't catch the error !!
Same code( this.test() ) I wrote in one of the button handlers in my component it did catch the error !!
I am not sure why this behavior ??

That's great! So we don't need this plugin any more right ?

What we have to do in functional component (there is not componentDidCatch)?
