ComposableMethod.invoke(...) cannot be called in a way that allows using the default values. What I've tried is to pass null as whichever parameter I want to be the default value, but it doesn't work. Sometimes you want to set a value in the end of the parameter list and the current implementation only allows it if we set all of the parameters before that one. Since the default values are not available to the developer (for example when using a library), it makes it impossible to work with it properly.

Actually, the implementation seems kind of buggy. In line 127 the method sets a default value mask if the argument is null, but in line 138 the implementation retrieves the null value successfully instead of using a default value. This potentially results in the java Method being called with a null value for an argument that is not supposed to be null (e.g. a float).

My suggestion would be to add some kind of a marker object that can be placed in the argument list of the invoke(...) call and it will act as the placeholder for a default value.
