解析Dart/Flutter中的嵌套JSON

import 'dart:convert';

void main() {
  String jsonString = '''
  {
    "name": "John Doe",
    "age": 30,
    "address": {
      "street": "123 Main Street",
      "city": "New York",
      "country": "USA"
    },
    "hobbies": ["reading", "hiking", "coding"]
  }
  ''';

  Map<String, dynamic> jsonData = json.decode(jsonString);

  String name = jsonData['name'];
  int age = jsonData['age'];
  String street = jsonData['address']['street'];
  String city = jsonData['address']['city'];
  String country = jsonData['address']['country'];
  List<String> hobbies = List<String>.from(jsonData['hobbies']);

  print('Name: $name');
  print('Age: $age');
  print('Street: $street');
  print('City: $city');
  print('Country: $country');
  print('Hobbies: $hobbies');
}
