Might have been asked before but I can't find it but how do you pass a arguments to a named route?
This is how I build my routes
Widget build(BuildContext context) {
return new Navigator(
initialRoute: 'home/chooseroom',
onGenerateRoute: (RouteSettings settings) {
WidgetBuilder builder;
switch (settings.name) {
case 'home/chooseroom':
// navigates to 'signup/choose_credentials'.
builder = (BuildContext _) => new ChoosePage();
break;
case 'home/createpage':
builder = (BuildContext _) => new CreateRoomPage();
break;
case 'home/presentation':
builder = (BuildContext _) => new Presentation();
break;
default:
throw new Exception('Invalid route: ${settings.name}');
}
return new MaterialPageRoute(builder: builder, settings: settings);
},
);
This is how you call it
Navigator.of(context).pushNamed('home/presentation')
But what if my widget is new Presentation(arg1, arg2, arg3)
?
