unnecessary_new

Stable

Recommended

Fix available

Unnecessary new keyword.

AVOID new keyword to create instances.

BAD:

dart

class A { A(); }
m(){
  final a = new A();
}

GOOD:

dart

class A { A(); }
m(){
  final a = A();
}

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

analysis_options.yaml

yaml

linter:
  rules:
    - unnecessary_new

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

analysis_options.yaml

yaml

linter:
  rules:
    unnecessary_new: true
