Flutter extracting data from a list inside a map from API call

Question

I have a flutter http get request that returns a response in the below format

{
   
    "area": "some area",
    "user_places": [
        {
            "place_id": "105",
            "place_name": "Place 1"
        },
        {
            "place_id": "104",
            "place_name": "place 2"
        }
    ],
    "lang": null,
    "token": "IiwiZGV2aWNlIjoid2ViIiwiZGllIjoiMjAyMS0wNS0xMiAyMjo0NTozOSJ9.2wJlmHNRmQ0_rfNbca2-DNek1dzT9Em8-iQIfGFZJ98",
    "account_type": 1,
    
}

Am currently able to get data from a field directly below the map for example "area" . My question is how to get data from a list inside the map in this case "user_places". Say I wanted to display all "place_id" and "place_name" in a widget somewhere in my app. How would I go about it?

you can use a tool like json to dart you can paste your json data and get a dart class of the same

class MyLocation {
  String area;
  List<UserPlaces> userPlaces;
  String lang;
  String token;
  int accountType;

  MyLocation(
      {this.area, this.userPlaces, this.lang, this.token, this.accountType});
....

then MyLocation.userPlaces you can access your data
