Detect current screen breakpoint

I am using Material UI to build my user interface for the web. I have a question regarding material UI if it provides a way to detect the current screen resolution breakpoint, ex: [xs, sm, md, lg, xl] or [0px, 600px, 900px, 1200px, 1536px] in a way that I can read it.
For instance, I wanted to use the useEffect() for cleaning a state in my component, but I needed that to be when the component hides because of a screen resolution change, so maybe I can do it like:
useEffect(()=> setMenuList(null), [mui.currentScreenResolution] )
In other words, in case the current screen breakpoints changed from 'xs' to 'md', I want this useEffect hook to run.
Does MUI provide a way to read the currently used breakpoint by the app?
Update:
Just to confirm my question; I don't want to detect every time the window size of the browser changes, I only want to detect when the screen resolution changes from one of the predefined screen resolution breakpoints by mui from one to another (ex: xs → md).

Disable landscape orientation in react app

I am building an app with reactJS. I am using webpack,sass and ajax for running the app and fetching data. I am in search of a function/logic where i can disable the landscape view. I want my app to be available only in portrait view and even if the user rotates it's phone, in the landscape view the app should not get resized.
I am finding solutions where there are options to customise this using tools. I need a solution where i can add this option similar to adding javascript code.

Set iPhone native popup's orientation

I've built a PhoneGap app for iPhone. In specific cases, landscape design and support was required, and so I've listened to device orientation notifications, and had my JS app add a '.landscape' css class which rotated the main container by 90 or -90 degrees.
This JS orientation handling was easy and quick, but the problem is the native interface is always portrait-oriented. When native popups are shown, they're always in portrait mode, even if the device is tilted to landscape.
Is there any way to set the orientation of native popups, without having to change the interface orientation (which is basically what I do in JS)?
Or do I have to rebuild the whole thing with proper native landscape orientation?
