unnecessary_const

Avoid const keyword.

AVOID repeating const keyword in a const context.

BAD:

class A { const A(); } m(){  const a = const A();  final b = const [const A()]; } 

GOOD:

class A { const A(); } m(){  const a = A();  final b = const [A()]; } 

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

linter:  rules:  - unnecessary_const 

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

linter:  rules:  unnecessary_const: true
