Dart default class for an interface

Question

Dart introduce default class for an interface like-
//---------------------------

interface Dartinterface default BasicInterface{

MyInterface();

Dartinterface();

}

class BasicInterface implements Dartinterface{

MyInterface(){

print("I an a inteface");

}

void main(){

//BasicInterface obj = new BasicInterface();

Dartinterface obj = new Dartinterface();

obj.MyInterface();
}

-----------------------------------------------//

but i can not understood what is the main advantage of that default class interface.

The idea is to provide a default implementation of the interface. Provided that the interface also provides a constructor you can then create a default object which implements the interface by instantiating the interface itself: Dartinterface obj = new Dartinterface(); I can't say I care much for this feature which makes the distinction between classes and interfaces rather hazy.
