How to fire a callback when window variable changes using JS

Question

I have a window variable accessible in my webview like window.x Android/iOS is changing the value of x based on certain conditions, problem is this value changes but react is not able to rerender based on said change since its not a state.

Is there any way to fire a callback when this value changes without polling it continuously?

If you know which function is changing the variable, you can hook into it and add handler that runs after it. Something like this — Brother58697

@Brother58697 the code triggering the variable change is running in Android/iOS native code, can I trigger an event in react from native code via a method channel or something? — Amartya Mishra

Found a better way to communicate events to a webview running on Android/iOS, requires minor changes to native code.
