unnecessary_constructor_name

Unnecessary .new constructor name.

PREFER using the default unnamed Constructor over .new.

Given a class C, the named unnamed constructor C.new refers to the same constructor as the unnamed C. As such it adds nothing but visual noise to invocations and should be avoided (unless being used to identify a constructor tear-off).

BAD:

class A {  A.new(); // LINT } ​ var a = A.new(); // LINT 

GOOD:

class A {  A.ok(); } ​ var a = A(); var aa = A.ok(); var makeA = A.new; 

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

linter:  rules:  - unnecessary_constructor_name 

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

linter:  rules:  unnecessary_constructor_name: true
