I am making a global TextFormField widget for the App. But it is not returning data in the controller. My Global text form field Widget: Kindly tell me what I am doing wrong. I am initializing the controller in the SignUp person widget. I also want to validate the text form field in the validator.
import 'package:flutter/material.dart';
class GlobalTextField extends StatelessWidget {
final Widget fieldIcon;
final String fieldText;
final TextEditingController fieldController;
final bool isEnabled;
const GlobalTextField(
this.fieldIcon,
this.fieldText,
this.fieldController, [
this.isEnabled,
]);
@override
Widget build(BuildContext context) {
return TextFormField(
controller: fieldController,
enabled: isEnabled ?? true,
decoration: InputDecoration(
hintText: fieldText,
prefixIcon: fieldIcon,
hintStyle: TextStyle(color: Colors.grey),
filled: true,
fillColor: Colors.white70,
enabledBorder: UnderlineInputBorder(
borderSide: BorderSide(color: Color.fromRGBO(198, 57, 93, 1)),
),
focusedBorder: UnderlineInputBorder(
borderSide: BorderSide(color: Color.fromRGBO(198, 57, 93, 1)),
),
),
cursorColor: Color.fromRGBO(198, 57, 93, 1),
);
}
}
I used it like
import 'package:flutter/material.dart';
import 'package:neighbourhood_watch/ui/widgets/button_global.dart';
import 'package:neighbourhood_watch/ui/widgets/textfield_global.dart';
import 'package:neighbourhood_watch/widgets/user_image_picker.dart';
import 'dart:io';
class SignUpPerson extends StatefulWidget {
@override
_SignUpPersonState createState() => _SignUpPersonState();
}
class _SignUpPersonState extends State<SignUpPerson> {
TextEditingController username = new TextEditingController();
TextEditingController description = new TextEditingController();
TextEditingController contact = new TextEditingController();
TextEditingController password = new TextEditingController();
TextEditingController area = new TextEditingController();
TextEditingController email = new TextEditingController();
final _formKey = GlobalKey<FormState>();
File _userImageFile;
void _pickedImage(File image) {
_userImageFile = image;
