BlocListener that reacts to the state changes of the FormBloc.

Properties

bloc → FormBloc2?
The bloc whose state will be listened to. Whenever the bloc's state changes, listener will be invoked.
finalinherited
child → Widget?
The Widget which will be rendered as a descendant of the BlocListener.
no setteroverride
formBloc → FormBloc2?
If the formBloc parameter is omitted, FormBlocListener will automatically perform a lookup using BlocProvider.of<FormBloc> and the current BuildContext.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
listener → BlocWidgetListener<FormBlocState<SuccessResponse, ErrorResponse>>
The BlocWidgetListener which will be called on every state change. This listener should be used for any code which needs to execute in response to a state change.
finalinherited
listenWhen → BlocListenerCondition<FormBlocState<SuccessResponse, ErrorResponse>>?
An optional listenWhen can be implemented for more granular control over when listener is called. listenWhen will be invoked on each bloc state change. listenWhen takes the previous state and current state and must return a bool which determines whether or not the listener function will be invoked. The previous state will be initialized to the state of the bloc when the BlocListener is initialized. listenWhen is optional and if omitted, it will default to true.
finalinherited
onDeleteFailed → FormBlocListenerCallback<FormBlocDeleteFailed<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the FormBlocState._isValidByStep is false and FormBloc.submit is called.
final
onDeleteSuccessful → FormBlocListenerCallback<FormBlocDeleteSuccessful<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the FormBlocState._isValidByStep is false and FormBloc.submit is called.
final
onDeleting → FormBlocListenerCallback<FormBlocDeleting<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the FormBlocState._isValidByStep is false and FormBloc.submit is called.
final
onFailure → FormBlocListenerCallback<FormBlocFailure<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the form are submitting and fail. The previous state must be FormBlocSubmitting.
final
onLoaded → FormBlocListenerCallback<FormBlocLoaded<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when you can submit the FormBloc.
final
onLoadFailed → FormBlocListenerCallback<FormBlocLoadFailed<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when you failed to pre/fill the fieldBlocs. The previous state must be FormBlocLoading.
final
onLoading → FormBlocListenerCallback<FormBlocLoading<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when you need to pre/fill the fieldBlocs usually with asynchronous data. The previous state must be FormBlocLoading.
final
onSubmissionCancelled → FormBlocListenerCallback<FormBlocSubmissionCancelled<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state that you must yield last in the method FormBloc.onCancelingSubmission. The previous state must be FormBlocSubmitting.
final
onSubmissionFailed → FormBlocListenerCallback<FormBlocSubmissionFailed<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the FormBlocState._isValidByStep is false and FormBloc.submit is called.
final
onSubmitting → FormBlocListenerCallback<FormBlocSubmitting<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the FormBloc is submitting. It is called automatically when FormBloc.submit is called successfully, and usually is used to update the submission progress.
final
onSuccess → FormBlocListenerCallback<FormBlocSuccess<SuccessResponse, ErrorResponse>, SuccessResponse, ErrorResponse>?
It is the state when the form is submitted successfully. The previous state must be FormBlocSubmitting.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
