반복되는 keyword를 줄여 준다..
final addressBook = AddressBookBuilder();
addressBook.name = “kims”
addressBook.address = “kims@box.cokr”
addressBook.phone = PhoneNumberBuilder();
addressBook.phone.number = ‘111-1111-1111’
addressBook.phone.tag = “Office” ).build()
addressBook.build();
를 아래와 같이 간결하게 변경 할 수 있다.
final addressBook = ( AddressBookBuilder()
..name = “kims”
..address = “kims@box.cokr”
..phone = ( PhoneNumberBuilder()
..number = ‘111-1111-1111’
..tag = “Office” ).build())
.build();
StringBuffer sb = new StringBuffer()
..write(“test1”)
..write(“test2”)
..write(“test3”);
print(“text : ” + sb.toString());
이렇게 줄여 쓸수도…
