avoid_field_initializers_in_const_classes

Avoid field initializers in const classes.

此规则自 Dart 2.0 版本起可用。

AVOID field initializers in const classes.

Instead of final x = const expr;, you should write get x => const expr; and not allocate a useless field. As of April 2018 this is true for the VM, but not for code that will be compiled to JS.

BAD:

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

GOOD:

class A {
  get a => const [];
  const A();
}

要启用 avoid_field_initializers_in_const_classes 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 avoid_field_initializers_in_const_classes ：

linter:
  rules:
    - avoid_field_initializers_in_const_classes
