The pagebuilder in GoRoute has the the only place I can grab the state.params, I want to update my StateNotifier when the route changes if it is different.
final LibraryRoutes = Provider<RouteBase>((ref) {
return ShellRoute(
navigatorKey: _LibraryKey,
builder: (context, state, child) {
return LibraryHomePage(
child: child,
);
},
routes: [
//dashboard
GoRoute(
path: "/library/:LibraryKey/Dashboard",
pageBuilder: (context, state) {
final String passedValue = state.params['LibraryKey']!;
final newLibrary = LibraryReadDto(LibraryKey: passedValue);
//this line error's out because its during lifecycle method
ref.read(AsyncLibraryProvidor.notifier).updateLibrary(newLibrary);
final AsyncLibraryNotifier = ref.watch(AsyncLibraryProvidor);
return AsyncLibraryNotifier.when(data: (data) {
return NoTransitionPage(
child: Text("dashboard"),
);
}, error: (_, __) {
return NoTransitionPage(
child: const Text("An error occurred"),
);
}, loading: () {
return NoTransitionPage(
child: CircularProgressIndicator(),
);
});
}),
]);
});
I've managed to put the update in a future to get around the problem is there a more elegant solution as the library is used in many different places.
GoRoute(
path: "/library/:LibraryKey/Dashboard",
pageBuilder: (context, state) {
if (ref.read(LibraryProvider) == null) {
final String passedValue = state.params['LibraryKey']!;
try {
//can't update during widget tree delay by 150 micoseconds so we can update after future
Future.delayed(
const Duration(microseconds: 150),
() {
final newLibrary = LibraryReadDto(LibraryKey: passedValue);
ref.read(LibraryProvider.notifier).updateLibrary(newLibrary);
},
);
} on Exception catch (ex) {
print(ex.toString());
}
}
return NoTransitionPage(
child: Text("dashboard"),
);
}),
