Selected item shown twice in the dropdown

[nilpkthmsk]

I use onFind to filter the items list for the dropdown, but the selected on will be duplicated, and shown twice in the dropdown. Any work around ?

Thank you in advance.

[salim-lachdhaf]

[nilpkthmsk]

[salim-lachdhaf]

could you past an example of your code

[nilpkthmsk]

  DropdownSearch(
    mode: Mode.BOTTOM_SHEET,
    dropdownSearchDecoration: InputDecoration(
      labelText: context.localeString("Currency"),
      hintText: context.localeString("Currency Hint"),
      contentPadding:
          const EdgeInsets.fromLTRB(12, 12, 0, 0),
      border: const OutlineInputBorder(),
    ),
    showSearchBox: true,
    // showClearButton: true,
    searchFieldProps: TextFieldProps(
        decoration: InputDecoration(
      labelText: context.localeString("Currency Search"),
      contentPadding: const EdgeInsets.all(12),
      border: const OutlineInputBorder(),
    )),
    items: Currency.list,
    onChanged: (CurrencyUnit? c) => {Currency.save(c!)},
    onFind: (String? filter) =>
        Currency.findAll(keyword: filter),
    itemAsString: (CurrencyUnit? c) => c.toString(),
    selectedItem: Currency.load(),
  ),

For Currency.findAll, I use the filter to make list, and return the new list with it.

i think you have somthinng wrong in your data. try to use isFilteredOnline to true

[nilpkthmsk]

I tried setting the isFilteredOnline to true, but the result remains the same. I tried to print the data in the filter function, and it is like below.

flutter: THB
flutter: 1

THB = filtered text 1 = length of the list return The same result goes for no isFilteredOnline setting. And I found another error, don't know if it's related.

I encounter the same issue, just remove the onFind function, it seems like the itemAsString is enough
