Hi @SteveOye, can you please clarify what expression you mean? Please check the documentation and make sure you using the package correctly.

from flutter_country_picker.

Relatively new to flutter. But what I did was install the package and added that code to a column. @Daniel-Ioannou and the error was attached to the code

See screenshot

from flutter_country_picker.

showCountryPicker show a bottom sheet, you can add a bottom sheet inside a column.
Check the flutter documentation HERE.

If you want user to select country inside a registration form use something like this:

InkWell(
  onTap: () {
    showCountryPicker(
      context: context,
      onSelect: (Country country) {
        setState(() => _country = country);
      },
    );
  },
  child: InputDecorator(
    decoration: InputDecoration(
      labelText: "Select country",
    ),
    child: _country != null ? Text(_country!.name) : null,
  ),
),

Note: Use "InputDecorator" to match the rest of the text fields in the form.
