import 'dart:convert'; // Importing dart:convert library for json conversion
import 'dart:io'; // Importing dart:io for file operations

void main() {
  // Create a map object that represents our JSON data
  Map<String, dynamic> jsonData = {
    "name": "John Doe",
    "age": 30,
    "address": {
      "street": "123 Main St",
      "city": "Anytown",
      "state": "CA",
      "zip": "12345"
    },
    "phoneNumbers": [
      {"type": "home", "number": "555-555-5555"},
      {"type": "work", "number": "555-555-5555"}
    ]
  };

  // Use the jsonEncode() function from the dart:convert library to convert the map object to a JSON string
  String jsonString = jsonEncode(jsonData);

  // Create a File object representing the file we want to write to
  File file = File("example.json");

  // Use the writeAsStringSync() method to write the JSON string to the file
  file.writeAsStringSync(jsonString);
}
