cascade_invocations

Cascade consecutive method invocations on the same reference.

DO Use the cascading style when successively invoking methods on the same reference.

BAD:

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

BAD:

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

GOOD:

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

GOOD:

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

To enable the cascade_invocations rule, add cascade_invocations under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - cascade_invocations

If you're instead using the YAML map syntax to configure linter rules, add cascade_invocations: true under linter > rules:

linter:
  rules:
    cascade_invocations: true
