Question

如何在 dart 中移植这个常量？

const CHANNEL_STATES = {
  closed: "closed",
  errored: "errored",
  joined: "joined",
  joining: "joining",
  leaving: "leaving",
}

您可以使用类和常量静态成员来做到这一点:

class CHANNEL_STATES {
  static const String closed = "closed";
  static const String errored = "errored";
  static const String joined = "joined";
  static const String joining = "joining";
  static const String leaving = "leaving";
}
