By default, go_router comes with default error screens for both `MaterialApp` | |
and `CupertinoApp` as well as a default error screen in the case that none is | |
used. You can also replace the default error screen by using the | |
[errorBuilder](https://pub.dev/documentation/go_router/latest/go_router/GoRouter/GoRouter.html) | |
parameter: | |
```dart | |
GoRouter( | |
/* ... */ | |
errorBuilder: (context, state) => ErrorScreen(state.error), | |
); | |
``` |
