How can I Sign up a user on firebase? - firebase

Question

I want to sign up a user on firebase that I store in a variable.
Here is my code :
import 'package:flutter/material.dart';
import 'package:login_signup/constants/constants.dart';
import 'package:login_signup/ui/widgets/custom_shape.dart';
import 'package:login_signup/ui/widgets/customappbar.dart';
import 'package:login_signup/ui/widgets/responsive_ui.dart';
import 'package:login_signup/ui/widgets/textformfield.dart';
import 'package:email_validator/email_validator.dart';
class SignUpScreen extends StatefulWidget {
#override
_SignUpScreenState createState() => _SignUpScreenState();
}
class _SignUpScreenState extends State<SignUpScreen> {
bool checkBoxValue = false;
double _height;
double _width;
double _pixelRatio;
bool _large;
bool _medium;
TextEditingController emailEditingController = TextEditingController();
String email;
void validation() {
// email should be instantiated here
email = emailEditingController.text;
bool emailvalidated = EmailValidator.validate(email);
if (emailvalidated) {
print('Email validated');
} else{
print('email not validated');
}
}
Widget clipShape() {
return Stack(
children: <Widget>[
Opacity(
opacity: 0.75,
child: ClipPath(
clipper: CustomShapeClipper(),
child: Container(
height: _large
? _height / 8
: (_medium ? _height / 7 : _height / 6.5),
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.orange[200], Colors.pinkAccent],
),
),
),
),
),
Opacity(
opacity: 0.5,
child: ClipPath(
clipper: CustomShapeClipper2(),
child: Container(
height: _large
? _height / 12
: (_medium ? _height / 11 : _height / 10),
decoration: BoxDecoration(
gradient: LinearGradient(

],
color: Colors.white,
shape: BoxShape.circle,
),
child: GestureDetector(
onTap: () {
print('Adding photo');
},
child: Icon(
Icons.add_a_photo,
size: _large ? 40 : (_medium ? 33 : 31),
color: Colors.orange[200],
)),
),
],
);
}
Widget form() {
return Container(
margin: EdgeInsets.only(
left: _width / 12.0, right: _width / 12.0, top: _height / 20.0),
child: Form(
child: Column(
children: <Widget>[
firstNameTextFormField(),
SizedBox(height: _height / 60.0),
lastNameTextFormField(),
SizedBox(height: _height / 60.0),
emailTextFormField(),
SizedBox(height: _height / 60.0),
phoneTextFormField(),
SizedBox(height: _height / 60.0),
passwordTextFormField(),
],
),
),
);
}
Widget firstNameTextFormField() {
return CustomTextField(
keyboardType: TextInputType.text,
icon: Icons.person,
hint: "First Name",
);
}
Widget emailTextFormField() {
return CustomTextField(
// assign your email controller to the custom text field here,
keyboardType: TextInputType.emailAddress,
icon: Icons.email,
hint: "Email ID",
textEditingController: emailEditingController,
);
}
Widget acceptTermsTextRow() {
return Container(
margin: EdgeInsets.only(top: _height / 100.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Checkbox(
activeColor: Colors.orange[200],
value: checkBoxValue,
onChanged: (bool newValue) {
setState(() {
checkBoxValue = newValue;
});
}),
Text(
"I accept all terms and conditions",
style: TextStyle(
fontWeight: FontWeight.w400,
fontSize: _large ? 12 : (_medium ? 11 : 10)),
),
],
),
);
}
Widget button() {
return RaisedButton(
elevation: 0,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(30.0)),
onPressed: () {
validation();
},
padding: const EdgeInsets.all(12.0),
child: Text(
'SIGN UP',
style: TextStyle(fontSize: _large ? 14 : (_medium ? 12 : 10)),
),
),
);
}
I would appreciate your help.
But I need to auto login for my app too and thanks again.

I guess what you are asking is to sign in with firebase to your app using Email and Password.
In that case. The article below covers all what you want.
