How to ignore a lint rule for entire file in Flutter?

Question

I am able to ignore the rule for individual variables like this:

class Class {
  // ignore: prefer_final_fields
  var _count = 0;

  // ignore: prefer_final_fields
  var _count2 = 0;
}

I want to use something like this but it doesn't work. How can I ignore the lint for entire class?

// ignore: prefer_final_fields (DOESN'T WORK)
class Class {
  var _count = 0;

  var _count2 = 0;
}

Answer 1

To ignore a rule

• For entire file:

  Use ignore_for_file instead of simple ignore:

  // ignore_for_file: prefer_final_fields (WORKS)
  class Class {
    var _count = 0;
  
    var _count2 = 0;
  }
  

• For whole project:

  Open analysis.options.yaml file located at the root of your project and add the following lines:

  linter:
    rules:
      prefer_final_fields: false
