How to get binding property in ViewCell

I know in ViewCell you can bind value to a View's property like:

var lbl1 = new Label();

lbl1.setBinding(Label.TextProperty, "value_from_binding_setup_in_listvew");

But is there a way to get the string value from "value_from_binding_setup_in_listvew"
in code I want something like this:
string str = BindingContext.getBindingValue("value_from_binding_setup_in_listvew");
