RegExp not working with the Validation Form in flutter?

This is a part of a project regarding feedback forms.
I already manage to create the validation form properly thanks to the answers here in StackOverflow developers.
But the problem is creating this regular expression which seems to not work on the validation form. I found in flutter docs the Iterable but I do not know how can I implement it on the dart page.

You can use this validator:
validator: (emailOfuser) {
if (emailOfuser == null || emailOfuser.isEmpty) {
return 'Please enter your Email';
} else if (emailOfuser.isNotEmpty) {
String emailOfuser1 = emailOfuser.toString();
String pattern = r'\w+#\w+\.\w+';
if (RegExp(pattern).hasMatch(emailOfuser1) == false) {
return 'Please enter your Email Properly';
}
}
return null;
},

try to implement like this:
import 'package:flutter/material.dart';
class EmailValidationForm extends StatefulWidget {
const EmailValidationForm({Key? key}) : super(key: key);
#override
State<EmailValidationForm> createState() => _EmailValidationFormState();
}
class _EmailValidationFormState extends State<EmailValidationForm> {
final GlobalKey<FormState> formKey = GlobalKey<FormState>();
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Email Validation'),
),
body: Form(
key: formKey,
child: Column(
children: [
TextFormField(
autofocus: false,
maxLength: 300,
keyboardType: TextInputType.emailAddress,
autocorrect: false,
validator: (email) {
if (email!.isEmpty) {
return 'required field';
} else if (email.trim().contains(' ')) {
return 'contain space';
} else if (!emailValid(email)) {
return 'invalid email';
}
return null;
},
onSaved: (email) {
return debugPrint(email);
},
),
ElevatedButton(
onPressed: () {
if (formKey.currentState!.validate()) {
formKey.currentState!.save();
}
},
child: const Text('Validate')),
],
),
),
);
}
}
bool emailValid(String email) {
final RegExp regex = RegExp(
r"^(([^<>()[\]\\.,;:\s#\']+(\.[^<>()[\]\\.,;:\s#\']+)*)|(\'.+\'))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$");
return regex.hasMatch(email.trim());

Flutter(VSCode): Ignoring header X-Firebase-Locale because its value was null

Warning: Ignoring header X-Firebase-Locale because its value was null.
I'm getting this warning while signing up a user in firebase. When i signup in my app it doesn't get added into firebase?(I'm working on flutter in VS Code). Code for my Signup Page is being written below:

how to create dual checkbox in flutter

I want to create two checkbox next to each other and when one of them is checked, the other one be unchecked but I don`t know how to do that in flutter, so I'll be wonderful if someone could help me.
here is my codes:
bool isMan = false;
bool isWoman = false;
Padding(
padding: EdgeInsets.only(right: 10),
child: Text(
"Man:",
style: TextStyle(color: Colors.white, fontSize: 20),
),
),
Theme(
data: ThemeData(unselectedWidgetColor: Colors.white),
child: Checkbox(
value: isMan,
checkColor: Color(0xfff44336),
activeColor: Colors.white,
onChanged: (value) {
setState(
() {
isMan = value!;
},
);
},
),
),
Text(
"Woman:",
style: TextStyle(color: Colors.white, fontSize: 20),
),
Theme(
data: ThemeData(unselectedWidgetColor: Colors.white),
child: Checkbox(
value: isWoman,
checkColor: Color(0xfff44336),
activeColor: Colors.white,
onChanged: (value) {
setState(
() {
isWoman = value!;
},
);
},
),
),

Here is the solution.
bool isMan = false;
bool isWoman = false;
Center(
child: Row(
children: [
Padding(
padding: EdgeInsets.only(right: 10),
child: Text(
"Man:",
style: TextStyle(color: Colors.white, fontSize: 20),
),
),
Theme(
data: ThemeData(unselectedWidgetColor: Colors.white),
child: Checkbox(
value: isMan,
checkColor: Color(0xfff44336),
activeColor: Colors.white,
onChanged: (value) {
setState(
() {
isMan = value!;
isWoman = false;
},
);
},
),
),
Text(
"Woman:",
style: TextStyle(color: Colors.white, fontSize: 20),
),
Theme(
data: ThemeData(unselectedWidgetColor: Colors.white),
child: Checkbox(
value: isWoman,
checkColor: Color(0xfff44336),
activeColor: Colors.white,
onChanged: (value) {
setState(
() {
isWoman = value!;
isMan = false;
},
);
},
),
),
],
),
)

When checkbox is un/checked - change other checkbox value
bool isMan = false;
bool isWoman = false;
#override
Widget build(BuildContext context) {
return Row(children: [
Text("Man:"),
Checkbox(
value: isMan,
onChanged: (value) {
setState(() {
isMan = value!;
isWoman = !value; # or set it to false
});
}),
Text("Woman:"),
Checkbox(
value: isWoman,
onChanged: (value) {
setState(() {
isWoman = value!;
isMan = !value; # or set it to false
});
})
]);
}

flutter firestore update data method

I'm trying to update the card data I brought from firestore
when I use onTap in Inkwell I want to change data in this card.
this is my search service. I am using this for bring data from firestore
how can I make update function on this situation. thanks for help
class SearchService {
List<Future<QuerySnapshot>> searchByName() {
return [
Firestore.instance
.collection('dis')
.where('no')
.orderBy('date', descending: true )
.getDocuments(),
];
}
}
this is my Card code
Widget buildResultCard(BuildContext context , data) {
return Card(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0)),
elevation: 5,
child: ExpansionCard(
title: Column(
children: [
Row(
children: [
Padding(
padding: EdgeInsets.fromLTRB(5, 0, 5, 1),
child: Text(data['isim'],
style: GoogleFonts.montserrat(color: Colors.blueGrey[700], fontSize: 20 , textStyle: TextStyle(fontWeight: FontWeight.w400)),
textAlign: TextAlign.center,

),
InkWell(
child: Icon(
Icons.update,
color: Colors.white54,
),
onTap: (){//I want to set update function here//
},
)
],
),
);
}
and this is my adddata function
Future<void> addData(carData) async {
if (isLoggedIn()) {
Firestore.instance.collection('dis').add(carData).catchError((e) {
print(e);
});
} else {
print('You need to be logged in');

Flutter Step Validation

I cannot validate Steps individually. I can validate fields in a Stepper, problem is that I want to validate fields before going to the next step.
Creating multiple forms is not a good option. I tried that and it is not practical. Is there any way to either:
Detect the current step and validate fields only inside that step
A simple way to validate step by step, not on submit

Use List<GlobalKey<FormState>> to control each step's validation
When user click continue do formKeys[currStep].currentState.validate()
You can copy paste run full code below
code snippet
List<GlobalKey<FormState>> formKeys = [GlobalKey<FormState>(), GlobalKey<FormState>(), GlobalKey<FormState>(), GlobalKey<FormState>()];
...
return Container(
child: Form(
key: _formKey,

Stepper(
steps: steps,
type: StepperType.vertical,
currentStep: this.currStep,
onStepContinue: () {
setState(() {
if(formKeys[currStep].currentState.validate()) {
if (currStep < steps.length - 1) {
currStep = currStep + 1;
} else {
currStep = 0;
}
}
});
},
...
List<Step> steps = [
Step(
title: const Text('Name'),
//subtitle: const Text('Enter your name'),
isActive: true,
//state: StepState.error,
state: StepState.indexed,
content: Form(
