I´m newbie to flutter and reveice one exception about route, I don't why I am getting this error in the debug console 'could not find a generator for route RouteSettings("org_Item", null) in the _WidgetsAppState.'
provinces_item.dart
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:let_us_volunteer/screens/orgscreen.dart';
class provwidget extends StatelessWidget {
final String id;
final String title;
final String image;
provwidget(this.id, this.title, this.image);
void selectOrg(BuildContext ctx) {
Navigator.of(ctx).pushNamed(orgscreen.routeName);
}
@override
Widget build(BuildContext context) {
return InkWell(
onTap: () => selectOrg(context),
child: Image.asset(image),
);
}
}
main.dart
import 'package:flutter/material.dart';
import 'package:let_us_volunteer/screens/log_in.dart';
import 'screens/page_view.dart';
import 'screens/log_in.dart';
import 'screens/orgscreen.dart';
void main() async {
runApp(page_view());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'flutter demo',
theme: ThemeData(
primarySwatch: Colors.purple,
primaryColor: Colors.purple,
),
home: const log_in_screen(),
routes: {
'/': (context) => log_in_screen(),
orgscreen.routeName: (context) => orgscreen(),
},
);
}
}
orgscreen.dart
import 'package:flutter/material.dart';
class orgscreen extends StatefulWidget {
static const routeName = 'org_Item';
@override
State<orgscreen> createState() => _orgscreenState();
}
class _orgscreenState extends State<orgscreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('ggg')),
body: null,
);
}
}
If someone knows the solution it would be grateful for help, and explaining what was wrong, thanks

Try to remove your home: const log_in_screen(),
and for format case use '/org_Item';
title: 'flutter demo',
theme: ThemeData(
primarySwatch: Colors.purple,
primaryColor: Colors.purple,
),
routes: {
'/': (context) => log_in_screen(),
orgscreen.routeName: (context) => orgscreen(),
},
And not sure about your page_view
, you can check
runApp(MyApp());
CodePudding user response:
The correct way of define route is use /
with it, So change your route to this:
static const routeName = '/org_Item';
when yo do not run your main class (MyApp) in your runApp, it can not define that route, so also correct this:
runApp(MyApp());
last thing when you define /
this in your routes, you should not use home
property of MaterialApp
, so remove home: const log_in_screen(),
and your final MaterialApp should look like this:
MaterialApp(
title: 'flutter demo',
theme: ThemeData(
primarySwatch: Colors.purple,
primaryColor: Colors.purple,
),
routes: {
'/': (context) => log_in_screen(),
orgscreen.routeName: (context) => orgscreen(),
},
)
