Properties

child Widget
The Widget which will be rendered as a descendant of the BlocListener.
final
cubit → FormBloc
The cubit whose state will be listened to. Whenever the cubit's state changes, listener will be invoked.
final, inherited
formBloc → FormBloc
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. [...]
@nonVirtual, read-only, inherited
key Key
Controls how one widget replaces another widget in the tree. [...]
final, inherited
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.
final, inherited
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 cubit 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 cubit when the BlocListener is initialized. listenWhen is optional and if omitted, it will default to true. [...]
final, inherited
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.
read-only, inherited
