How to pass selected answer in this array

Answer 1

Flutter/Dart doesn't have arrays. Use lists instead.

Answer 2

Solution
In the api-response ,it's always formatted into either List of Map or Map of List.
List of Map is Like :
[
{
"name":"ruby",
"gender":"female"
},
{
"name":"otis",
"gender":"male"
},
]
And, Map of List is Like :
{
"data": [
"Professor",
"Berlin",
"Tokyo"
]
}
So to access them you have to use JsonDecode and then look the response and process that.
For Map response ....
var resMap = jsonDecode(response.body);
For List response (use key after resMap with key)...
var resMap = jsonDecode(response.body);
var infoList = resMap["data"];
Demo
class CatTypeController {
Future<void> getLeaves() async {
String url = "https://meowfacts.herokuapp.com/?count=2";
http.Response response = await http.get(Uri.parse(url));
if (response.statusCode == 200) {
Map rM = jsonDecode(response.body);
print(rM["data"]);
}
}
}
Response
Output
["In ancient Egypt, killing a cat was a crime punishable by death.","The way you treat kittens in the early stages of it's life will render it's personality traits later in life."]
