Alert dialogue not displaying even with show dialogue - flutter

Question

I changed it to stateful and used return dialogue but still nothing.
void main() {
runApp(
MyApp(),
);
}
class MyApp extends StatefulWidget {
#override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
createAlertDialogue(BuildContext context) {
TextEditingController customeController = TextEditingController();
return showDialog(
context: context,
builder: (context) {
return AlertDialog(
title: Text(" Your NAme"),
content: TextField(
controller: customeController,
),
actions: <Widget>[
MaterialButton(
elevation: 5.0,
child: Text('submit'),
onPressed: () {},
)
],
);
});
}
Widget _buildForgotPasswordBtn(BuildContext ctx) {
return Container(
alignment: Alignment.centerRight,
child: TextButton(
onPressed: () {
setState(() {
createAlertDialogue(ctx);
});
},
child: Text(
'forgot password',
style: kLabelStyle,
),
),
);
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
backgroundColor: Color.fromARGB(206, 5, 42, 146),
body: SafeArea(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
_buildForgotPasswordBtn(context),
],
),
),
),
);
}
}
I used setState and even put ctx in createalertdialogue because it didn't work until I changed from context to this.
I don't get any errors but I get nothing when I press the forgot password button on the emulator.
The button is there and can be pressed with no errors but still nothing appears.

I Just slightly edited your code
Wrap your runApp with MaterialApp
from
void main() {
runApp(
MyApp(),
);
}
to
void main() {
runApp(
MaterialApp(
home: MyApp(),
),
);
}
your full code
import 'package:flutter/material.dart';
void main() {
runApp(
MaterialApp(
home: MyApp(),
),
);
}
class MyApp extends StatefulWidget {
#override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
createAlertDialogue(BuildContext context) {
TextEditingController customeController = TextEditingController();
return showDialog(
context: context,
builder: (context) {
return AlertDialog(
title: Text(" Your NAme"),
content: TextField(
controller: customeController,
),
actions: <Widget>[
MaterialButton(
elevation: 5.0,
child: Text('submit'),
onPressed: () {},
)
],
);
});
}
Widget _buildForgotPasswordBtn(BuildContext ctx) {
return Container(
alignment: Alignment.centerRight,
child: TextButton(
onPressed: () {
setState(() {
createAlertDialogue(ctx);
});
},
child: Text(
'forgot password',
),
),
);
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
backgroundColor: Color.fromARGB(206, 5, 42, 146),
body: SafeArea(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
_buildForgotPasswordBtn(context),
],
),
),
),
);
}
}
