Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
addFieldError(String error, {bool? isDirty}) → void
It is useful when you want to add errors that you have obtained when submitting the FormBloc.
addRule(ValidationType rule) → void
addRules(Set<ValidationType> rules) → void
addValidator(Validator<Value> validator, {bool forceValidation = false}) → void
addValidators(Set<Validator<Value>> validators, {bool forceValidation = false}) → void
changeAvailability(bool enabled) → void
changeData(dynamic data) → void
changeExtraData(dynamic extraData) → void
changeLoading(bool loading) → void
changeReadOnly(bool readOnly) → void
changeRequirement(bool required, {bool forceValidation = false}) → void
changeRules(Set<ValidationType> rules) → void
changeValidators(Set<Validator<Value>> validators, {bool forceValidation = false}) → void
changeValue(Value value, {bool forceChange = false}) → void
clear({bool force = false}) → void
override
clearRules() → void
clearValidators() → 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(State state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
focusChanged() → void
getError(Value value, {Set<String? Function(Value)>? newValidators}) → String?
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<State> 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
removeFormBloc(FormBloc formBloc) → void
override
removeRule(ValidationType rule) → void
removeRules(Set<ValidationType> rules) → void
removeValidator(Validator<Value> validator, {bool forceValidation = false}) → void
removeValidators(Set<Validator<Value>> validators, {bool forceValidation = false}) → void
reset({bool force = false}) → void
override
toNullableString() → String?
toString() → String
A string representation of this object.
override
updateFormBloc(FormBloc formBloc) → void
override
updateInitial(Value value, {bool forceChange = false}) → void
validate() → bool
override

Operators

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