When i run this application and enter location then I got an error in my log cat which is " Bad state: Cannot add event after closing".

LocationScreen.build. (package:restaurant\_finder/UI/location\_screen.dart:58:44)

It indicates the code  
onChanged: (query) =\> bloc.submitQuery(query),

in LocationScreen class.

So how i can fix this issue.

The error “Bad state: Cannot add event after closing” indicates that the bloc has been closed and is no longer accepting events. Ensure that the bloc is still active when `submitQuery` is called. One way to fix this is by checking if the bloc is closed before calling `submitQuery`:

```auto
onChanged: (query) {
  if (!bloc.isClosed) {
    bloc.submitQuery(query);
  }
},

```

This should prevent the error by ensuring events are only added when the bloc is active [check here](https://lacalculadora-alicia.es/).
