Bug: Using variable names with '$' creates syntax errors in generated file.

[iamsupercode]

To Reproduce:

• Create A Page that takes a parameter named user$id
• Register Page in autoroutes
• Run flutter packages pub run build_runner build --delete-conflicting-outputs
• Check app_route.gr.dart for syntax errors

In my case the result is this result below. Note the bolded text.

`
// ....app_route.gr.dart
final String venue$id;

@OverRide
String toString() {
return 'ReservationBuilderRouteArgs{key: $key, onCreateReservation: $onCreateReservation, venue$id: $venue$id}';
}`

i don't know, why use $ for naming variable, just try revoke $ at your naming variable. it will solve the problem.
