List returnMovies = [];
Future<List> _getData() async {
final response = await http.get("https:../getTodayMovies",
headers: {HttpHeaders.AUTHORIZATION: Acess_Token.access_token});
if (response.body != null) {
returnMovies = json.decode(response.body);
.....
setState(() {});
} else {
final responseUpcoming = await http.get("/upcoming",
headers: {HttpHeaders.AUTHORIZATION: Acess_Token.access_token});
returnMovies = json.decode(responseUpcoming.body);
}
The response.body looks like:
[{"id":394470548,"host_group_name":"heyab redda","movie_image":"..png","type":"horror","code":"X123","name":"Lovely","start_time":1554364800,"end_time":1554393600,"}]
The responseUpcoming.body looks like:
{"id":394470545,"host_group_name":"foo redda","movie_image":".png","type":"horror","code":"X123","name":"Lovely","start_time":1554364800,"end_time":1554393600,"}, {"id":394470548,"host_group_name":"foo1 redda","movie_image":"..png","type":"comic","code":"X125","name":"Lovely1","start_time":1554364800,"end_time":1554393600,"}
The error I get is: String, dynamic is not a subtype of type List<dynamic>
.
In the first API call that I am doing I normally get in return an array of objects, however, when this is empty, the second API call returns a list of objects that I want to push into the array called returnMovies, how can I achieve this?? Is there any way to .push these objects in the array?? So then I want to use this array to build dynamically a Listview.builder. Also is it correct the way I am declaring it? I am quite new on Dart. Thank you

When you do this json.decode(response.body)
you are getting a List
of Map
you should use List<dynamic> movieListData
and get the items like this:
movieListData = json.decode(response.body);
returnMovies = movieListData.map((dynamic movieData) {
String id = movieData['_id'];
String host_group_name = movieData['host_group_name'];
String duration = movieData['duration'];
return new Movie(id,title, duration);
}).toList();

I will suggest to use
returnMovies.addAll({your object here})

Sounds like you are looking for addAll
returnMovies.addAll(json.decode(returnUpcoming.body))
