Can I have another form of an enum value?

Question

I have an enum in client code describing a list of endpoints in the API:

enum Requests { GetUsers, GetProducts, ... }

I want to send requests to server having these values, like connection.sendRequest(Requests.GetUsers).

Now, in the sendRequest() function I want the enum value to be converted to something like '/users'.

Can I attach methods to each enum similar to this below?

enum Requests {
    GetUsers.toString: '/users',
    GetPendingDomains: '/prodcuts'
}

Perhaps old-style enums like shown in http://stackoverflow.com/a/15854550/217408 are better for your use case. — Günter Zöchbauer, Mar 15 '17 at 08:19

Not directly in the enum (enums are really basic in Dart). You have to create a Map<Requests, String> aside to handle the associated paths.

enum Request { GetUsers, GetProducts, ... }
final paths = <Request, String>{
  Request.GetUsers:    '/users',
  Request.GetProducts: '/products',
}
