Obj<T> class

A base-class that store a value of T.

You can create a new Obj:

// usign the `Obj` class
final strObj = Obj<String>("initial value");
final intObj = Obj<int>(0);
final userObj = Obj<User>(User());

You can get the value:

// usign a `value` getter
print(strObj.value);
// or using the callable
print(strObj());
// or using `toString` implicit
print("$intObj");

You can set a new value:

// usign a `value` setter
strObj.value = "change value";
// or using the callable
strObj("change value");
