An extension that adds methods like when to an AsyncValue.

Properties

asData → AsyncData<T>?: Upcast AsyncValue into an AsyncData, or return null if the AsyncValue is in loading/error state.
no setter
data → AsyncData<T>?: Upcast AsyncValue into an AsyncData, or return null if the AsyncValue is in loading/error state.
no setter
value → T?: Attempts to synchronously.
no setter

map<R>({required R data(AsyncData<T> data), required R error(AsyncError<T> error), required R loading(AsyncLoading<T> loading)}) → R: Perform some action based on the current state of the AsyncValue.
mapOrNull<R>({R data(AsyncData<T> data)?, R error(AsyncError<T> error)?, R loading(AsyncLoading<T> loading)?}) → R?: Perform some actions based on the state of the AsyncValue, or return null if the current state wasn't tested.
maybeMap<R>({R data(AsyncData<T> data)?, R error(AsyncError<T> error)?, R loading(AsyncLoading<T> loading)?, required R orElse()}) → R: Perform some actions based on the state of the AsyncValue, or call orElse if the current state was not tested.
maybeWhen<R>({R data(T data)?, R error(Object error, StackTrace? stackTrace)?, R loading()?, required R orElse()}) → R: Switch-case over the state of the AsyncValue while purposefully not handling some cases.
when<R>({required R data(T data), required R error(Object error, StackTrace? stackTrace), required R loading()}) → R: Performs an action based on the state of the AsyncValue.
whenData<R>(R cb(T value)) → AsyncValue<R>: Shorthand for when to handle only the data case.
whenOrNull<R>({R data(T data)?, R error(Object error, StackTrace? stackTrace)?, R loading()?}) → R?: Perform actions conditionally based on the state of the AsyncValue.
