A generic way to know if application running on TeaVM (not GWT) in core project

[antzGames]

I need a way to determine if the application is running on teaVM in the core project other than using ApplicationType.WebGL

I think this is an important question because I am sure that there are many existing libGDX projects and libraries that use ApplicationType.WebGL to point to native GWT methods.

Now with teaVM, we can use full java/kotlin implementations.

Anyhow, is there any field or property that can be access in the core project that allows me to know if the application is running in TeaVM?

Side note: Should we ask libGDX maintainers to add ApplicationType.TeaVM?

BTW, I have a solution to this problem but it is not elegant.

You want to know if WebGL is teavm or GWT ?

I think we can use system property to check it. I added a useragent from javascript. We can add more properties.

So the OR is mutually exclusive, which means I need to differentiate if its running TeaVM exclusively. Maybe an pseudo code if statement will explain it better:

if (teaVM) {
  ...
} else if (GWT) {
   ....
} else {
 ...
}
