FormBuilderDropdown using style from CupertinoPicker

[brizaldi]

is there a way to customize FormBuilderDropdown so that it can use style similar to CupertinoPicker when user choose the item?

As it is currently, the package doesn't support Cupertino style fields.
I would suggest you use FormBuilderCustomField to build your own custom field

Like so:

var options = ["Option 1", "Option 2", "Option 3"];

FormBuilderCustomField(
  attribute: "name",
  validators: [
    FormBuilderValidators.required(),
  ],
  formField: FormField(
    enabled: true,
    builder: (FormFieldState<dynamic> field) {
      return InputDecorator(
        decoration: InputDecoration(
          labelText: "Select option",
          contentPadding:
              EdgeInsets.only(top: 10.0, bottom: 0.0),
          border: InputBorder.none,
          errorText: field.errorText,
        ),
        child: Container(
          height: 200,
          child: CupertinoPicker(
            itemExtent: 30,
            children: options.map((c) => Text(c)).toList(),
            onSelectedItemChanged: (index) {
              field.didChange(options[index]);
            },
          ),
        ),
      );
    },
  ),
),
