I think its a Map(keys,values) and inside the key(success) we have another Map

How i can get access into a specific element?

CodePudding user response：

I will assume that this value is assigned to a map type variable, I will name it response

so to access the id :

response["success"]["data"][0]["id"]

CodePudding user response：

for ex. that is my data

const String _SexData = """[
  {
    "sex": "Seçiniz / Choice",
    "x": 1000
  },
  {
    "sex": "Male",
    "x": 1001
  },
  {
    "sex": "Female",
    "x": 1002    
  }
]""";

and I calling it;

DropdownButton<int>(
                      iconEnabledColor: Colors.blue,
                      dropdownColor: const Color.fromARGB(255, 28, 185, 242),
                      style: const TextStyle(color: Colors.black),
                      value: sex?.x ?? 1000,
                      items: model1.sexs.map((a) {
                        return DropdownMenuItem(
                          child: Text(a.sex,
                              style: const TextStyle(color: Colors.white)),
                          value: a.x,
                          onTap: () {
                            setState(() {
                              sex = a;
                            });
                          },
                        );
                      }).toList(),
                      onChanged: (s) {},
                    ),
