The argument type 'NyTextField Function(NyTextField)' can't be assigned to the parameter type 'String?'

[jeremyj11]

Trying to use the style parameter of Field to perform an inline style override, I copied the below from the docs:

@override
    fields() => [
        Field("Name", 
            style: (NyTextField nyTextField) => nyTextField.copyWith(
                decoration: InputDecoration(
                    labelText: "Name",
                    hintText: "Enter your name",
                ),
            ),
        ),

but get the error: The argument type 'NyTextField Function(NyTextField)' can't be assigned to the parameter type 'String?'.

I'm new to Flutter and Nylo, so maybe I'm missing something obvious? I can see that style needs to be a string in ny_form.dart though.. so perhaps your docs are for a future version?? I'm on nylo version 5.32.7

My full form file:

import 'package:flutter/material.dart';
import 'package:nylo_framework/nylo_framework.dart';

class ReminderForm extends NyFormData {
  ReminderForm({String? name}) : super(name ?? "reminder");

  @override
  fields() => [
        Field(
          "Name",
          style: (NyTextField nyTextField) => nyTextField.copyWith(
            decoration: InputDecoration(
              labelText: "Name",
              hintText: "Enter your name",
            ),
          ),
        ),
        Field(
          "datetime",
          cast: FormCast.datetime(
            dateFormat: DateFormat.Hm(),
            initialPickerDateTime: DateTime.now(),
            mode: DateTimeFieldPickerMode.time,
          ),
          dummyData: null,
          style: "compact",
        ),
        Field("notes", cast: FormCast.textArea(), style: "compact"),
      ];
}

Thanks in advance for any advice, and as a dev coming from Laravel - this framework is very cool!
