Go_Router Pass Object to new route - flutter

Question

I want to pass object from the listview to the sub route. It seems no way to pass the object.
Is there any how to do it?
GoRouter routes(AuthBloc bloc) {
return GoRouter(
navigatorKey: _rootNavigatorKey,
routes: <RouteBase>[
GoRoute(
routes: <RouteBase>[
GoRoute(
path: loginURLPagePath,
builder: (BuildContext context, GoRouterState state) {
return const LoginPage();
},
),
GoRoute(
path: homeURLPagePath,
builder: (BuildContext context, GoRouterState state) =>
const HomePage(),
routes: <RouteBase>[
GoRoute(
path: feeURLPagePath,
name: 'a',
builder: (context, state) => FeePage(),
routes: [
/// Fee Details page
GoRoute(
name: 'b',
path: feeDetailsURLPagePath,
builder: (BuildContext context, GoRouterState state) =>
const FeeDetails(),
),
]),
],
),
],
path: welcomeURLPagePath,
builder: (BuildContext context, GoRouterState state) =>
const SplashPage(),
),
],
refreshListenable: GoRouterRefreshStream(bloc.stream),
debugLogDiagnostics: true,
initialLocation: welcomeURLPagePath,
},
);
}
The error says no initial match found for feeDetails!

Answer 1

Use extra parameter in context.goNamed()
Example:
Object:
class Sample {
String attributeA;
String attributeB;
bool boolValue;
Sample(
{required this.attributeA,
required this.attributeB,
required this.boolValue});}
Define GoRoute as
GoRoute(
path: '/sample',
name: 'sample',
builder: (context, state) {
Sample sample = state.extra as Sample; // -> casting is important
return GoToScreen(object: sample);
},
),
Call it as:
Sample sample = Sample(attributeA: "True",attributeB: "False",boolValue: false)
context.goNamed("sample",extra:sample );
Receive it as:
class GoToScreen extends StatelessWidget {
Sample? object;
GoToScreen({super.key, this.object});
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Text(
object.toString(),
style: const TextStyle(fontSize: 24),
)),
);
}
}
