How can I make FormBuilderTextField validators reusable? - flutter

Question

So I am making a sign up page in Flutter. I'm gonna use this "flutter_form_builder" and "form_builder_validators" packages. I will make the textfields reusable to save time, and everything works, except the validators.
This is my reusable widget:
class MyFormBuilderTextField extends StatelessWidget {
final String name;
final Color inputTextColor;
final String labelText;
final Color labelColor;
final bool filled;
final Color fillColor;
final double borderRadius;
final Color enabledBorderColor;
final Color focusedBorderColor;
final FormFieldValidator<String> validators;
MyFormBuilderTextField({
required this.name,
this.inputTextColor = const Color(0xFFFFFFFF),
required this.labelText,
this.labelColor = Colors.white54,
this.filled = true,
this.fillColor = const Color(0xFF131313),
this.borderRadius = 10.0,
this.enabledBorderColor = Colors.white12,
this.focusedBorderColor = const Color(0xFFF57B3B),
required this.validators,
});
#override
Widget build(BuildContext context) {
return FormBuilderTextField(
name: name,
style: TextStyle(color: inputTextColor),
decoration: InputDecoration(
labelText: labelText,
labelStyle: TextStyle(color: labelColor),
filled: filled,
fillColor: fillColor,
enabledBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(borderRadius),
borderSide: BorderSide(color: enabledBorderColor),
),
focusedBorder: OutlineInputBorder(
borderRadius: BorderRadius.circular(borderRadius),
borderSide: BorderSide(color: focusedBorderColor),
),
),
validator:validators,
);
}
}
This is how I tried implementing it:
class MyFormBuilder extends StatefulWidget {
#override
State<MyFormBuilder> createState() => _MyFormBuilderState();
}
class _MyFormBuilderState extends State<MyFormBuilder> {
final _formKey = GlobalKey<FormBuilderState>();
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Color(0xFF070707),
body: _buildContent(),
);
}
Widget _buildContent() {
return SingleChildScrollView(
padding: EdgeInsets.all(24.0),
child: FormBuilder(
key: _formKey,
child: Column(
children: <Widget>[
SizedBox(height: 30.0),
MyFormBuilderTextField(
name: 'password',
labelText: 'Password',
validators: [
FormBuilderValidators.min(8),
FormBuilderValidators.required(),
],
),
],
),
)
);
}
}
I am getting this error:
The argument type 'String? Function(String?)' can't be assigned to the parameter type 'List<String? Function(String?)>'.dartargument_type_not_assignable
How can I make the validators reusable?
