import 'package:http/http.dart' as http;
import 'dart:convert';

Future<Map<String, dynamic>> fetchJsonData() async {
  final response = await http.get(Uri.parse('YOUR_API_URL'));
  if (response.statusCode == 200) {
    return json.decode(response.body);
  } else {
    throw Exception('Failed to load JSON data');
  }
}

{
  "name": "John",
  "age": 30,
  "email": "john@example.com"

Map<String, dynamic> jsonData = await fetchJsonData();
String name = jsonData['name'];
int age = jsonData['age'];
