CustomDropdown with display name and code

I am using a widget called CustomDropdown from the animated_custom_dropdown 3.1.1 package.

Here's my current structure:

`List<Map<String, dynamic>>` data

[
    {
        "code": "140100000",
        "name": "Abra"
    },
    {
        "code": "160200000",
        "name": "Agusan del Norte"
    },
    {
        "code": "160300000",
        "name": "Agusan del Sur"
    },
    {
        "code": "060400000",
        "name": "Aklan"
    },
    {
        "code": "050500000",
        "name": "Albay"
    }
]

CustomDropDown widget

CustomDropdown<
    Map<String, dynamic>>.search(
  validateOnChange: true,
  canCloseOutsideBounds: true,
  decoration: CustomDropDownStyle
      .customDropdownSearchDecorationClass(
          context,
          isDarkMode), // to write code once
  items: address,
  initialItem:
      address[0],
  hintText: "Select one",
  onChanged: (value) {
    final valueCode = value?['code'];
    debugPrint(
        'Selected province $valueCode');
  },
)

Unexpected output

What I'm trying to achieve is to display only the name in the CustomDropdown list. However, if the user selects a specific province, it should then pass a corresponding code.

The crucial part is the code because it uniquely corresponds to the next address type. However, users should only see the name, not the List<Map<String, dynamic>> data format list.

Yet I have no idea what to do here.

Thanks in advance!

Solution

Here's my workaround

I've added these two properties:

listItemBuilder: (context, item,
        isSelected, onItemSelect) =>
    Text(item['name']),
headerBuilder: (context,
        selectedItem, enabled) =>
    Text(selectedItem['name']),

Which will then be like this:

CustomDropdown<
    Map<String, dynamic>>.search(
  validateOnChange: true,
  canCloseOutsideBounds: true,
  decoration: CustomDropDownStyle
      .customDropdownSearchDecorationClass(
          context,
          isDarkMode), // to write code once
  items: address,
  initialItem:
      address[_defaultDropdownIndex],
  hintText: "Select one",
  listItemBuilder: (context, item,
          isSelected, onItemSelect) =>
      Text(item['name']),
  headerBuilder: (context,
          selectedItem, enabled) =>
      Text(selectedItem['name']),
  onChanged: (value) {
    final valueCode = value?['code'];
    debugPrint(
        'Selected province $valueCode');
  },
)

Eventually, the problem was solved, and here's the expected output:

If I selected Abra:

I/flutter ( 1234): Selected province 140100000
