[abhihasabe]

1. How to avoid to enter special characters.

2. If you search some think but no data found that time not getting msg No data found.

3. How to remove space from left side (It take some padding, when we select some data), i want to remove space.

Hello @abhihasabe ,

1. I don't think there is an easy way to validate the entered search keyword. The closest I could think of would be to provide a keyboardType argument. For example TextInputType.number if you want only numbers.

2. Indeed, having a message when no item is found is a missing feature. This is recorded as #33 .

3. There has been an interesting discussion on padding in #35 . You may want to have a look at the proposed workarounds.

Hi @abhihasabe ,

Sorry, I get no error and no unreasonable behavior related to focus with the following code:

SearchableDropdown.single(
        items: items,
        value: selectedValue,
        hint: "Select one",
        searchHint: "Select one",
        onChanged: (value) {
          setState(() {
            selectedValue = value;
          });
        },
        isExpanded: true,
        selectedValueWidgetFn: (item) {
          return Container(
              transform: Matrix4.translationValues(-10,0,0),
              alignment: Alignment.centerLeft,
              child: (Text(item.toString())));
        },
        underline: Container(
          height: 1.0,
          padding: const EdgeInsets.only(right: 13.0),
          margin: const EdgeInsets.only(right: 13.0),
          decoration: BoxDecoration(
              border:Border(bottom: BorderSide(color: Colors.teal, width: 3.0))
          ),
        ),
      )

Can you please explain what you mean by error and focus?
