React Native Platform OS is not working suddenly

Question

I am using Platform.OS to check ios and android. It is working fine, But suddenly it returns me 0 instead of 'ios' or 'android'. After some RND I found that when the app is loading the first time, it returns me 'android' but when I switch the screen and check Platform.OS then it returns me 0 value. I am wondered why it is happening.

I am sharing the console result.

when the app is reloading the first time.

 LOG  Platform.OS
 LOG  android

after that navigate to the other screen and then check Platform OS.

LOG  Platform.OS 
LOG  0

I am sharing the code snippet to check Platform

import { Platform } from 'react-native';

componentDidMount() {
        console.log('Platform.OS');
        console.log(Platform.OS);
}

Answer 1

It looks like you used Platform.OS "=" instead of "==" someplace within the code. Example :

wrong way:

(Platform.OS ='android')?console.log("this the wrong way):console.log('Oops')

right way

(Platform.OS=='android')?console.log("Youpi it works):console.log('in your dream, this gonna happen again')

Answer 2

The same thing happened to me.

I noted that in one place I have checked platform condition using a single equal operator by mistake like

paddingTop: (Platform.OS = 'android'? 16 : 4)

and then whenever I checked the platform, I always got 16.

So make sure if anywhere you have check condition, like Platform.OS = 'android' replace it with Platform.OS == 'android'
