Restricting orientation of some views

We have an application developed using ionic and Xamarin framework.
We have a requirement of restricting some of the views to Portrait.
Is it possible to restrict orientation for some views in ionic+Xamarin or even ionic+phonegap applications?

I found [this post][1] that states:

I am using these plugins :

$ cordova plugin add https://github.com/Adlotto/cordova-plugin-recheck-screen-orientation.git4
$ cordova plugin add net.yoik.cordova.plugins.screenorientation

Then in your app (usualy in config), just check which page that should be portrait or landscape (it’s more flexible rather than global preferences)

//check orientation
console.log('Orientation is ' + screen.orientation);
if(toState.orientation == 'portrait') {
  screen.lockOrientation('portrait');
}else{
  screen.lockOrientation('landscape');
}

perhaps it will help

that might be of some use to you
