This response is :

{
  "Total Amount": {
    "status": { "code": 200, "message": "success", "errors": [] },
    "data": {
      "total_amount": 500.0,
      "total_amount_currency": "EGP",
      "KIOSK": { "total_amount": 500.0, "total_amount_currency": "EGP" }
    },
    "count": null,
    "next": null,
    "previous": null
  }
}

and i want it only to print total amount to store it in string

CodePudding user response：

the response is the nested map

so you can get the total_amount as

final _data = value.data;
TotalAmount = _data['Total Amount']['data']['total_amount'];

NOTE: if you have control over api, do not use spaces in attributes i.e. Total Amount => total_amount

be sure to validate the data before fetching that as

if(value.data !=null || value.data.status.code == 200){
    final _data = value.data;
    TotalAmount = _data['Total Amount']['data']['total_amount'];
}
