Alert dialog reloads every time the textfield is clicked - flutter

Question

I am including an AlertDialog when the app user is not registered in Cloud Firestore:
class MuroScreen extends StatefulWidget {
const MuroScreen({Key? key}) : super(key: key);
#override
_MuroScreenState createState() => _MuroScreenState();
}
class _MuroScreenState extends State<MuroScreen> {
CollectionReference userRef = FirebaseFirestore.instance.collection('clientes');
Future<void> salir() async {
await FirebaseAuth.instance.signOut().catchError((error){
print(error.toString());
});
Navigator.of(context).push(MaterialPageRoute(builder: (c)=>MyHomePage001()),);
}
Future<void> verificarUsuario() async{
DocumentSnapshot snapshotUser = await userRef
.doc(FirebaseAuth.instance.currentUser!.phoneNumber)
.get();
print("existe?"+snapshotUser.exists.toString());
if(snapshotUser.exists){
//ya existe
print("si EXISTE");
}
else {
//no existe
print("no EXISTE");
var nameController = TextEditingController();
Alert(
context: context,
title: "LOGIN",
content: Column(
children: <Widget>[
TextField(
decoration: InputDecoration(
icon: Icon(Icons.account_circle),
labelText: 'Username',
),
),
TextField(
obscureText: true,
decoration: InputDecoration(
icon: Icon(Icons.lock),
labelText: 'Password',
),
),
],
),
buttons: [
DialogButton(
onPressed: () => Navigator.pop(context),
child: Text(
"LOGIN",
style: TextStyle(color: Colors.white, fontSize: 20),
),
)
]).show();
}
}
#override
void initState() {
// TODO: implement initState
super.initState();
verificarUsuario();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Home"),
),
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(
margin: EdgeInsets.all(65),
width: double.infinity,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
primary: Colors.red,
),
onPressed: () {
salir();
},
child: Text("Logout",style: TextStyle(color:Colors.white,fontSize: 16, fontWeight: FontWeight.bold),),
),
)
],
),
);
}
}
Alert is a rflutter_alert widget.
The issue is that every time I click on a textfield inside the alert widget, the screen reloads and shows the alert again without showing the keyboard, it reloads again.

Answer 1

You are calling the verificarUsuario(); in init() which doesn't have a context. The alert needs a context from build method to show. Please add a button inside the scaffold and open this alert after passing the the context as an argument. It should work.
