even though using _ denotes private, can I set it as a property?

I have 2 variables. model and _model. Essentially, model is going to be the property that people would bind to with my template. When it binds, it will set _model and then _model will be used in the dart and in the markup for the form binding.

My question is this. I know in Dart, the underscore is a denotation of a private variable. i wasnt sure if it being private encompasses the scope of the markup associated with the Dart class.

That being said. It seems that when I set:

_model = new Model();

the class understands it just fine, but if I want to notify the markup using set by way of:

set("_model", new Model());

the class doesnt understand it. It is almost as if there are 2 different scopes of _model. Maybe I can get by this by changing all references of _model to something like componentModel or something else which doesnt use an underscore at all.

Can someone explain this more clearly to me, because I think I am missing something when it comes to pre-pending an underscore and plausibly how set works.

Not sure what you expect from

_model = new Model();

This is normal code and expected to work.

set("_model", new Model());

needs to use reflection to set the value of the _model property and I'm pretty sure this can't work because there is no way to access private fields from another library. There could be a way for a transformer to change the code (for example add public getters and setters) that would allow code to access private members. But as far as I remember, this is not the case.
