#PREFER using ??=
over testing for null
.
As Dart has the
??=
operator, it is advisable to use it where applicable to
improve the brevity of your code.
BAD:
String get fullName {
if (_fullName == null) {
_fullName = getFullUserName(this);
}
return _fullName;
}
GOOD:
String get fullName {
return _fullName ??= getFullUserName(this);
}
