How to get List of Chromecast devices without CastButton

How to get List of Chromecast devices in Android without CastButton, as i am developing custom UI functionality.

Or is there a way to detect Chromecast device?

Hi. Currently, the cast device list is not accessible to React native, since that functionality is entirely provided by the android native MediaRouteButton.

I don't really have the opportunity to look into this during the coming weeks. PR's are always welcome!

I don't have time to look into this either but I can provide some links to help if you want to investigate it on your own.

Google Cast Api: https://developer.android.com/reference/android/support/v7/media/MediaRouter.html#getRoutes()
(I think this is the main method you will need. Transformations to make it readable will probably be needed but I am unsure without coding a little of it which as mentioned I can't do currently)

Code file with Exposed Java functions to React-Native:
./android/src/main/java/com/reactnativegooglecastv3/CastModule.java

Feel free to reach out if you have any questions on this.
