response_builder library

Key types

• Data Source
  • Request - Listenable data source for 3-state asynchronous data
  • ResultListenable and ResultNotifier - Listenable data source for 2-state synchronized data
• Build Protocols
  • BuildAsyncSnapshot - This protocol enable BuildAsyncSnapshotActions to consume 3-state data from Future, Stream or Request
  • BuildResult - This protocol enable enables BuildResultListenable to consume 2-state data from ResultListenable
  • BuildValue - This protocol enable enables BuildValueListenable to consume value from ValueListenable
  • WithEmptyValue - Protocol implement BuildValue.buildValue contract, which enables building actions to handle empty value
• Build Actions
  • BuildAsyncSnapshotActions - Actions run on BuildAsyncSnapshot protocol to consume 3-state AsyncResult data from Future, Stream or Request,
  • BuildResultListenable - Actions run on BuildResult protocol, to consume 2-state Result from ResultListenable
  • BuildValueListenable - Actions run on BuildValue protocol, to consume value from ValueListenable

Classes

DefaultBuildActions

Default building actions that used by BuildResultListenable and BuildAsyncResult

HistoryValueNotifier<T>

A ValueListenable implementation that kept the history of the changes

Request<T>

Request is a listenable data source that loads data in either synchronous or asynchronous manner.

ResultListenable<T>

An interface for subclasses of Listenable that expose a result.

ResultNotifier<T>

ResultNotifier is just like ValueNotifier but support to hold error along with value.

Mixins

BuildAsyncResult<T>

Protocol that builds 3-state async result, which can be:

BuildAsyncSnapshot<T>

Protocol that builds 3-state async result from a Future, a Stream or a Request

BuildResult<T>

Protocol that builds 2-state sync result, which could be either a value or an error BuildResult implements BuildValue

BuildValue<T>

Protocol that builds value

BuildWithBuilder

BuildWithBuilderInLocalContext

WithEmptyValue<T>

Protocol to build data which potentially could be empty

Extensions

BuildAsyncSnapshotActions

BuildResultListenable

Actions that depends on Protocol BuildResult

BuildValueListenable

Actions that depends on Protocol ValueListenable

Typedefs

ErrorFixer<T> = T Function(Object error)

Contract of error fixer

ValueUpdater<T> = T Function(T current)

Contract of synchronous value updater

ValueWidgetBuilder<T> = Widget Function(BuildContext context, T value)
