use_to_and_as_if_applicable

Start the name of the method with to/_to or as/_as if applicable.

From Effective Dart:

PREFER naming a method to___() if it copies the object's state to a new object.

PREFER naming a method as___() if it returns a different representation backed by the original object.

BAD:

class Bar {  Foo myMethod() {  return Foo.from(this);  } } 

GOOD:

class Bar {  Foo toFoo() {  return Foo.from(this);  } } 

GOOD:

class Bar {  Foo asFoo() {  return Foo.from(this);  } } 

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

linter:  rules:  - use_to_and_as_if_applicable 

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

linter:  rules:  use_to_and_as_if_applicable: true
