I want to achieve this:
For now, I have this:
This is my code:
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class LogInEnterEmailPassword extends StatefulWidget {
const LogInEnterEmailPassword({Key? key}) : super(key: key);
#override
State<LogInEnterEmailPassword> createState() => _LogInEnterEmailPasswordState();
}
class _LogInEnterEmailPasswordState extends State<LogInEnterEmailPassword> {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Color(0xffF6F6F6),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text("Enter Email",
style: TextStyle(
fontSize: 25,
fontStyle: FontStyle.normal,
fontWeight: FontWeight.normal,
color: Color(0xff313640),
),),
Text("______________________________",
style: TextStyle(
fontSize: 25,
fontStyle: FontStyle.normal,
fontWeight: FontWeight.normal,
color: Color(0xff313640),
),),
Text("Enter Password",
style: TextStyle(
fontSize: 25,
fontStyle: FontStyle.normal,
fontWeight: FontWeight.normal,
color: Color(0xff313640),
),),
Text("______________________________",
style: TextStyle(
fontSize: 25,
fontStyle: FontStyle.normal,
fontWeight: FontWeight.normal,
color: Color(0xff313640),
),),
],
)
)
);
}
}
I tried using sizedBox(), but no luck, my design shows a lot of space and I don't like that, it doesn't look great in my opinion, so, I have to erase the MainAxisAlignment to achieve the first design? Or what properties do I have to write?
Thank you in advance
Could you try to change MainAxisAlignment from spaceEvenly to center? You could see the difference between them.
Actually, I fully use SizeBox to separate them with specific spaces.
mainAxisAlignment: MainAxisAlignment.spaceEvenly
mainAxisAlignment: MainAxisAlignment.center
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: Padding(
padding: EdgeInsets.symmetric(horizontal: 24.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Flexible(
child: Hero(
tag: 'logo',
child: Container(
height: 200.0,
child: Image.asset('images/logo.png'),
),
),
),
SizedBox(
height: 48.0,
),
TextField(
keyboardType: TextInputType.emailAddress,
textAlign: TextAlign.center,
onChanged: (value) {
email = value;
//Do something with the user input.
}, decoration: kTextFieldDecoration.copyWith(hintText: 'Eenter your email')),
SizedBox(
height: 8.0,
),
TextField(
obscureText: true,
textAlign: TextAlign.center,
onChanged: (value) {
password = value;
//Do something with the user input.
},
decoration: kTextFieldDecoration.copyWith(hintText: 'Eenter your password')),
SizedBox(
height: 24.0,
),
RoundButton(
title: 'Register',
colour: Colors.blueAccent,
onPressed: () async{
print(email);
print(password);
print('Register');
//Go to login screen.
// Navigator.pushNamed(context, RegistrationScreen.id);
try{
final newUser = await _auth.createUserWithEmailAndPassword(email: email, password: password);
if (newUser != null) {
Navigator.pushNamed(context, ChatScreen.id);
}
}
catch(e) {
print(e);
}
},
),
],
),
),
);

Just wrap your ResetPassword() method like below:
if (_formKey.currentState!.validate()) {
Resetpassword();
}
This will check the validation.
Make sure key in attached to Form widget not Container
class ForgetPasswordForm extends StatefulWidget {
const ForgetPasswordForm({Key? key}) : super(key: key);
#override
_ForgetPasswordFormState createState() => _ForgetPasswordFormState();
}
class _ForgetPasswordFormState extends State<ForgetPasswordForm> {
final _formKey = GlobalKey<FormState>();
String email = "";
Future Resetpassword() async {
print("123");
}
#override
Widget build(BuildContext context) {
return SingleChildScrollView(
child: Form(
key: _formKey,
autovalidateMode: AutovalidateMode.disabled,
child: Container(
child: Container(
child: Padding(
padding: const EdgeInsets.all(30.0),
child: Column(children: [
TextFormField(
keyboardType: TextInputType.emailAddress,
decoration: const InputDecoration(
hintText: "Email",
hintStyle: TextStyle(
color: Colors.grey,
fontFamily: "Dubai",
fontSize: 14)),
validator: (String? Email) {
if (Email != null && Email.isEmpty) {
return "Email can't be empty";
}
return null;
},
onChanged: (String? text) {
email = text!;
print(email);
},
),
SizedBox(
height: 50,
),
Container(
child: TextButton(
child: Text("Reset Password"),
onPressed: () async {
if (_formKey.currentState!.validate()) {
Resetpassword();
}
},
),
)
]),
)))));
}
}
Add variable
final GlobalKey<FormState> keys = GlobalKey<FormState>();
validate like that
if (_keys.currentState!.validate()) {
Resetpassword();
}
I have two files...Workout.dart and Submit.dart. In Workout.dart I have variables: name, sets, rep, pmg, and smg.

To pass data from one widget to another you have to do two things,
Create a constructor of widget having data which it will accept,
Pass that data while calling it from another widget.
here is the code which solves your problem:
workout.dart
import "package:flutter/material.dart";
import './submit.dart';
class Workout extends StatefulWidget {
#override
_WorkoutState createState() => _WorkoutState();
}
class _WorkoutState extends State<Workout> {

#override

I Store the Meal and the Date in Cloud_Firestore. Getting it back, it looks like this shown on the Screen Show.
I tried to formate the Timestamp with DateTime but this doesn't work.
I also tried it with the intl.dart Package to format it,
How can I parse the Timestamp and Format it into Year,Month and Day?

You can try to convert it to date before printing.

I need to turn these two functions : _collectKeywords and _matchKeywords into a Widget, so I can reuse them another time. I have tried it, but I don't know how and where to instatiate the a widget that only processes data without returning any value. Can somebody help me?
