如何从 Bear.blackBear 中获取 black_bear

英文:

I have a simple enum in Flutter, say

enum Bear {
    panda,
    @JsonValue("black_bear") blackBear,
    @JsonValue("brown_bear") brownBear,
}

How do I retrieve black_bear from Bear.blackBear?

你可以使用增强枚举,

enum Animal {
  panda('panda'),
  blackBear("black_bear"),
  brownBear("brown_bear");

  const Animal(this.key);
  final String key;
}

你可以使用 Animal.blackBear.key; 来获取 black_bear

英文:

You can use enhanced enum,

enum Animal {
  panda('panda'),
  blackBear("black_bear"),
  brownBear("brown_bear");

  const Animal(this.key);
  final String key;
}

And you can use Animal.blackBear.key; to get black_bear .
