I am seeing isMounted() warning after I upgraded to latest React Native version 0.55.4.

Add the below code to your root index.js file. 

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

    you should rather explain why it is showing instead of muting those warnings – Hariharan L May 30 '18 at 04:41

    @HariharanL it is due to react native update that deprecated `isMounted` method, so you shouldn't worry about it so much. wait for the library developer to update it then you can update your react native dependencies too.. – Billy Koswara May 30 '18 at 06:27
  • @SirKoswara I am seeing this warning message too. I hoped to get an answer why it is so and how could I solve it, by clicking this question. but rather found a way to mute it. That's why I commented above. I know it is deprecated. It would be helpful to have a solution or workaround or update in function explanation here – Hariharan L May 30 '18 at 06:31
  • @HariharanL here is a link(https://reactjs.org/blog/2015/12/16/ismounted-antipattern.html), which has detailed explanation about the issue – MD Aslam Ansari May 30 '18 at 07:32
