BaseOperationCubit<TResult, Id> class abstract

Base cubit for single async operations (create, update, delete, toggle, etc.).

class DeleteItemCubit extends BaseOperationCubit<void, int> {
  final ItemRepository _repo;
  DeleteItemCubit(this._repo);

  Future<void> delete(int id) => execute(
    targetId: id,
    operation: () => _repo.delete(id),
  );
}

Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
close() → Future<void>
Closes the instance. This method should be called when the instance is no longer needed. Once close is called, the instance can no longer be used.
inherited
emit(BaseOperationState<Id> state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
execute({required Future<TResult> operation(), Id? targetId}) → Future<void>
Runs operation with automatic loading, success, and error state handling. Ignores the call if an operation is already in progress.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<BaseOperationState<Id>> change) → void
Called whenever a change occurs with the given change. A change occurs when a new state is emitted. onChange is called before the state of the cubit is updated. onChange is a great spot to add logging/analytics for a specific cubit.
inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError.
inherited
reset() → void
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
