cascade_invocations

Contents

Cascade consecutive method invocations on the same reference.

This rule is available as of Dart 2.0.

This rule has a quick fix available.

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

BAD:

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

BAD:

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

GOOD:

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

GOOD:

dartSomeClass 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:
