build method

@override Widget build({ required BuildContext context, required FormMapper mapper, required TypeProperty property, required Keywords args, })

build and bind the corresponding widget context a FormMapper mapper the FormMapper property a TypeProperty args and parameters that will be handled by the adapter

Implementation

@override
Widget build({required BuildContext context, required FormMapper mapper, required TypeProperty property, required Keywords args}) {
  WidgetProperty? widgetProperty = mapper.findWidgetById("$name:${property.path}"); // TODO

  var (displayValue, parseValue, validate, textInputType, inputFormatters) = customize(property);

  TextEditingController? controller;
  FocusNode? focusNode;

  if ( widgetProperty != null) {
    controller = widgetProperty.args["controller"];
    focusNode = widgetProperty.args["focusNode"];
  }
  else {
    controller = TextEditingController();
    focusNode = FocusNode();

    controller.addListener(() {
      mapper.notifyChange(property: property, value: parseValue(controller!.text));
    });
  } // else

  TextFormField result = TextFormField(
    key: ValueKey("$name:${property.path}"), // TODO was path
    controller: controller,
    focusNode: focusNode,
    style: args.get<TextStyle>('style'),
    validator: validate,
    keyboardType: textInputType,
    inputFormatters: inputFormatters
  );

  mapper.map(property: property, widget: result, adapter: this, displayValue: displayValue, parseValue: parseValue);

  if ( widgetProperty == null) {
    widgetProperty = mapper.findWidgetById("$name:${property.path}")!;

    widgetProperty.args["controller"] = controller;
    widgetProperty.args["focusNode"] = focusNode;
  }

  return result;
