Methods

map<TResult extends Object?>({required TResult idle(DataStateIdle<T> value), required TResult loading(DataStateLoading<T> value), required TResult error(DataStateError<T> value), required TResult success(DataStateSuccess<T> value)}) → TResult

Available on DataState<T>, provided by the DataStatePatterns extension

A switch-like method, using callbacks.

mapOrNull<TResult extends Object?>({TResult? idle(DataStateIdle<T> value)?, TResult? loading(DataStateLoading<T> value)?, TResult? error(DataStateError<T> value)?, TResult? success(DataStateSuccess<T> value)?}) → TResult?

Available on DataState<T>, provided by the DataStatePatterns extension

A variant of map that fallback to returning null.

maybeMap<TResult extends Object?>({TResult idle(DataStateIdle<T> value)?, TResult loading(DataStateLoading<T> value)?, TResult error(DataStateError<T> value)?, TResult success(DataStateSuccess<T> value)?, required TResult orElse()}) → TResult

Available on DataState<T>, provided by the DataStatePatterns extension

A variant of map that fallback to returning orElse.

maybeWhen<TResult extends Object?>({TResult idle()?, TResult loading()?, TResult error(Object error)?, TResult success(T? value)?, required TResult orElse()}) → TResult

Available on DataState<T>, provided by the DataStatePatterns extension

A variant of when that fallback to an orElse callback.
