title: Dart How To parse JSON With Unique Key, Value Pairs
body: <p>I am parsing a JSON object containing several key value pairs but am not sure how to make objects out of the JSON below. The keys are always different depending on the GET request so I am not able to use json['keyname'] like usual. What kind of function would I need in order to return a list of keys from 'ccwms' and a respective list of values (floats)?</p>
  
  <pre><code>    {
    "ccwms": {
      "frc118": 160.8076758518209,
      "frc1255": 15.257951313413884,
      "frc1296": 11.42077882954301,
      "frc7321": -161.58464745359254
    }
  }
  </code></pre>
