Warning: isMounted(…) is deprecated in plain Javascript Classes

Question

I am implementing 2 screens using react-navigation. But I got the warning below while navigating to the second page:

Warning: isMounted(...) is deprec

Answer 1

This is a problem with latest React Navigation and React Native. To silence it add:

import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Warning: isMounted(...) is deprecated', 'Module RCTImageLoader']);

I expect it will be fixed in React Navigation within next few weeks.
