有没有办法在 Flutter 中获取地图中单个对象的地图中的键值？

Question

I've searched a lot but could not find a case where one can retrieve the value of the key for a Map object. My use case involves retrieving data as a json from Http, decoding it to a map, then getting the data from the map, including the keys, and store it as an object. Most cases here talk about retrieving all the keys, which I don't want. My json structure is as follows, FWIW:

DB
|__jobs
    |___key1
          |____title
          |____company
          |____salary

Answer 1

I decided to change my factory in my classes so that I can pass the key as a parameter:

  factory Job.fromJson(String jobID, Map<String,dynamic> json) {
    return Job(
        uid: jobID,
    );
  }

And in my decode function:

    map.forEach((jobsID, jobsData) {
      _jobsList.add(Job.fromJson(jobsID, jobsData));
    });

I haven't tested whether it will cause issues in future though.
