CodePudding user response：

I think you're tring to implement your code as Map.

In order to use your JSON format in Dart, you need to make it Map first.

Map map = populars.asMap();

Then you can use it like that:

print(map[key])

CodePudding user response：

try this if you want to get the data inside your created json either ways there are more ways to it.

final getFeatures = populars.map((e)=> e['features']).first; 
  print(getFeatures[0]['type']);
  print(getFeatures[1]['rooms']);
  print(getFeatures[2]['toilet']);
  print(getFeatures[3]['parlor']);
  print(getFeatures[4]['water']);
 
//Result
Studio
1
1
1
true

CodePudding user response：

I think the issue is in the structure itself, it should be like this:

{
"name": "Single Villa",
"features": {
  "type": "Studio",
  "rooms": 1,
  "toilet": 1,
  "parlor": 1,
  "water": true
  }
},

then you can use it like this:

final name = populars[index]['name'];
final rooms = populars[index]['features']['rooms'];
