BAD:

dart
SomeClass someReference = SomeClass();
someReference.firstMethod();
someReference.secondMethod();

BAD:

dart
SomeClass someReference = SomeClass();
...
someReference.firstMethod();
someReference.aProperty = value;
someReference.secondMethod();

GOOD:

dart
SomeClass someReference = SomeClass()
    ..firstMethod()
    ..aProperty = value
    ..secondMethod();

GOOD:

dart
SomeClass someReference = SomeClass();
...
someReference
    ..firstMethod()
    ..aProperty = value
    ..secondMethod();
