Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
applyFilter(String filter) → void
clearFilter() → void
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(QueryState<T> state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
fetch({Q? query, bool silent = false}) → Future<void>
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<QueryState<T>> 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
refetch() → Future<void>
refresh({bool silent = true}) → Future<void>
toString() → String
A string representation of this object.
inherited
updateQuery(Q query) → void

Operators

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