I wanna update my state in dart, I have an event, state, and bloc file, and a funcion in another file, and when I call my function it doesnt update the state of my bloc.

this is a bloC from a widget in flutter, and when I use BlocProvider and gives a context, it works, but when I try to update it by a function that it will calling into a for x times, I need the function can update it.

//bloC
import 'package:bloc/bloc.dart';
import 'log_event.dart';
import 'log_state.dart';

class LogBloc extends Bloc<LogEvent, LogState>{
  LogBloc() : super(LogState(['123333334'])) {
    on<AddItemLogEvent>((event, emit) {
      print('AddItemLogEvent received');
      var updatedItems = List<String>.from(state.items)..addAll(['4444']);
      emit(LogState(updatedItems));
    });
  }
}

//event
abstract class LogEvent {}

class AddItemLogEvent extends LogEvent {
  
}

class EraseItemsLogEvent extends LogEvent {}  

//state

class LogState {
  List<String> items = <String>[];
  LogState(this.items);

}

//function

import 'package:app/bloc/log/log_event.dart';

import '../bloc/log/log_bloc.dart';

void addItem () async {
LogBloc bloc = LogBloc();
bloc.add(AddItemLogEvent());

}
