import 'package:flutter/material.dart';
import 'package:clickmeetplay/iam/user/postbean.dart';
import 'package:http/http.dart' as http;
class PostHome extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(home: Scaffold(body: PostScreen(),),);
}
}
class PostScreen extends StatefulWidget {
@override
_PostScreenState createState() => _PostScreenState();
}
class _PostScreenState extends State<PostScreen> {
List<Post> _postList =new List<Post>();
Future<List<Post> > fetchPost() async {
final response =
await http.get('http://alkadhum-col.edu.iq/wp-json/wp/v2/posts/');
if (response.statusCode == 200) {
List<dynamic> values=new List<dynamic>();
values = json.decode(response.body);
if(values.length>0){
for(int i=0;i<values.length;i++){
if(values[i]!=null){
Map<String,dynamic> map=values[i];
_postList .add(Post.fromJson(map));
debugPrint('Id-------${map['id']}');
}
}
}
return _postList;
} else {
throw Exception('Failed to load post');
}
}
@override
Widget build(BuildContext context) {
return Container();
}
@override
void initState() {
fetchPost();
}
}

Response res = await http.get(BASE_URL+'example');

List<dynamic> body = jsonDecode(res.body);
}
}
