Recommends to use ${ClassName}_${ClassMemberName} pattern for name argument in Intl.message(), Intl.plural(), Intl.gender(), Intl.select() methods.

Using the combination of the class and method names helps keeping all generated keys unique.

Example​

❌ Bad:

import 'package:intl/intl.dart';

class SomeButtonI18n {
  static final String title1 = Intl.message(
    'One Title',
    name: 'SomeButtonI18n_titleOne', // LINT: This name is expected to be 'SomeButtonI18n_title1'.
  );

  final String title2 = Intl.message(
    'Two Title',
    name: 'titleTwo', // LINT: This name is expected to be 'SomeButtonI18n_title2'.
  );

  String get title3 => Intl.message(
    'Three Title',
    name: 'SomeButtonI18n_titleThree', // LINT: This name is expected to be 'SomeButtonI18n_title3'.
  );

  static String get title4 => Intl.message(
    'Four Title',
    name: 'SomeButtonI18n_titleFour', // LINT: This name is expected to be 'SomeButtonI18n_title4'.
  );

  String title5() => Intl.message(
    'Five Title',
    name: 'SomeButtonI18n_titleFive', // LINT: This name is expected to be 'SomeButtonI18n_title5'.
  );

  static String title6() {
    return Intl.message(
      'Six Title',
      name: 'SomeButtonI18n_titleSix', // LINT: This name is expected to be 'SomeButtonI18n_title5'.
     );
  }
}

✅ Good:

import 'package:intl/intl.dart';

class SomeButtonCorrectI18n {
  static final int number = int.parse('1');

  static final String title1 = Intl.message(
    'One Title',
    name: 'SomeButtonCorrectI18n_title1'
  );

  final String title2 = Intl.message(
    'Two Title',
    name: 'SomeButtonCorrectI18n_title2'
  );

  String get title3 => Intl.message(
    'Three Title',
    name: 'SomeButtonCorrectI18n_title3'
  );

  static String get title4 => Intl.message(
    'Four Title',
    name: 'SomeButtonCorrectI18n_title4'
  );

  String get title5 => Intl.message(
    'Three Title',
    name: 'SomeButtonCorrectI18n_title5'
  );

  static String get title6 => Intl.message(
    'Four Title',
    name: 'SomeButtonCorrectI18n_title6'
  );
}
