  // Example 1: Merge two simple maps
  final a = {'name': 'Alice', 'age': 25};

  final mergedMap = ObjectModifier.mergeMap(a, b);
  print('Merged Map: $mergedMap');
  // Output: {name: Alice, age: 25, city: Paris}

  // Example 2: Merge list of maps with automatic ID detection

  // [
  //   {id: 1, name: Alice, age: 25},
  //   {id: 2, name: Bob},
