i am facing a new problem with my code, and honestly, I cant figure out where is my mistake , i have made the exact same widget in another file, and runs perfectly. I'm starting to believe that there is one problem with some widgets maybe.
I paste my code so you can check it out and tell me where is my mistake (very common ) or maybe is some widget/ line of code that is breaking the code.
import 'package:flutter/material.dart';
void main(List<String> args) {
runApp(MaterialApp(
home: Scaffold(
body: Products(),
),
));
}
class Products extends StatefulWidget {
Products({Key key}) : super(key: key);
@override
_ProductsState createState() => _ProductsState();
}
Class _ProductsState extends State<Products> {
@override
Widget build(BuildContext context) {
bool valoractual;
@override
void initState() {
super.initState();
valoractual = false;
}
return Scaffold(
appBar: AppBar(
backgroundColor: Color.fromRGBO(239, 180, 185, 1),
actions: <Widget>[
Icon(
Icons.search,
size: 25,
),
Switch(
activeColor: Colors.white,
inactiveThumbColor: Colors.blue[900],
value: valoractual,
onChanged: (bool cambio) {
setState(() {
valoractual = cambio;
});
//cambiovalor();
if (valoractual) {
showDialog(
context: context,
barrierDismissible: false,
builder: (context) => AlertDialog(
content: Text(" delete option"),
actions: [
FlatButton(
onPressed: () {
print("****************");
print(valoractual);
Navigator.of(context).pop();
return valoractual;
},
child: Text("Continue"),
)
],
),
);
} else {
showDialog(
context: context,
builder: (context) => AlertDialog(
content:
Text("view option"),
actions: [
FlatButton(
onPreenter code heressed: () {
print("****************");
print(valoractual);
Navigator.of(context).pop();
return valoractual;
},
child: Text("Aceptar"),
)
],
),
);
}
},
),
Icon(Icons.delete, size: 20),
],
),
body: Container(
margin: EdgeInsets.only(top: 10),
child: Text("this is sample text"),
),
);
}
}
try to put your initState function out of the build function
like
Class _ProductsState extends State<Products> {
bool valoractual;
@override
void initState() {
super.initState();
valoractual = false;
}
@override
Widget build(BuildContext context) {
return Scaffold(
