RefenaScope class - refena_flutter library

Constructors

RefenaScope({Key? key, PlatformHint? platformHint, List<ProviderOverride<BaseNotifier, dynamic>> overrides = const [], List<BaseProvider<BaseNotifier, dynamic>> initialProviders = const [], NotifyStrategy defaultNotifyStrategy = NotifyStrategy.identity, List<RefenaObserver> observers = const [], bool defaultRef = true, required Widget child}): Creates a RefenaScope. It will create an implicit RefenaContainer that will be disposed when the RefenaScope is disposed.
RefenaScope.withContainer({Key? key, required RefenaContainer container, PlatformHint? platformHint, bool ownsContainer = true, bool defaultRef = true, required Widget child}): Creates a RefenaScope that uses an existing RefenaContainer. By default, the RefenaScope will dispose the RefenaContainer when the RefenaScope itself is disposed. To prevent this, set ownsContainer to false.

Properties

child → Widget: The child widget
final
container → RefenaContainer: Returns the backing container. The container exposes more advanced methods for edge cases.
no setteroverride
debugLabel → String: A label to be used in debug messages and by the RefenaTracingPage.
no setteroverride
debugOwnerLabel → String: Returns the owner of this Ref. Usually, this is a notifier or a widget. Used by Ref.redux to log the origin of the action.
no setteroverride
defaultNotifyStrategy → NotifyStrategy: The default notify strategy
no setteroverride
disposed → bool: Whether the container has been disposed.
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
implicitContainer → bool: Whether this RefenaScope created its own RefenaContainer.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
observer → RefenaObserver?: The provided observer (e.g. for logging)
no setteroverride
ownsContainer → bool: Has ownership of the RefenaContainer. This is used to dispose the RefenaContainer when the widget is disposed.
final
platformHint ↔ PlatformHint: The platform hint.
getter/setter pairoverride
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

anyNotifier<N extends BaseNotifier<T>, T>(BaseProvider<N, T> provider) → N: Returns the notifier of a NotifierProvider. This method is used internally without any NotifyableProvider constraints.
override
cleanupListeners() → void: Removes disposed listeners from all notifiers. This happens regularly, but you can call it manually if you want to to visualize the current state.
override
createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<RefenaScope>: Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
dispose<N extends BaseNotifier<T>, T>(BaseProvider<N, T> provider) → void: Disposes a provider. Be aware that streams (ref.stream) are closed also. You may call this method in the dispose method of a stateful widget. Note: The provider will be initialized again on next access.
override
disposeContainer() → void: Disposes the container itself. It will also dispose all providers. After calling this method, the container should not be used anymore.
override
disposeFamilyParam<N extends FamilyNotifier<dynamic, P>, P>(BaseProvider<N, dynamic> provider, P param) → void: Disposes the param of a family provider. While the ordinary dispose method disposes the whole provider, this method only disposes the param.
override
ensureOverrides() → Future<void>: Awaiting this future will ensure that all overrides are initialized. Calling it multiple times is safe.
override
exists(BaseProvider<BaseNotifier, dynamic> provider) → bool: Whether the provider is initialized. Usually, providers are initialized when you first access them. They are also initialized when you override them. They are getting disposed when you call Ref.dispose.
override
future<N extends AsyncNotifier<T>, T>(AsyncNotifierProvider<N, T> provider) → Future<T>: Get the Future of an AsyncNotifierProvider.
override
getActiveNotifiers() → List<BaseNotifier>: Returns all active notifiers. Remember: A provider is stateless. The notifier holds the state.
override
getActiveProviders() → List<BaseProvider<BaseNotifier, dynamic>>: Returns all active providers. Remember: A provider is stateless. The notifier holds the state.
override
init() → void: Initializes the RefenaContainer.
override
internalDispose<N extends BaseNotifier<T>, T>(BaseProvider<N, T> provider, LabeledReference debugOrigin) → void: override
message(String message) → void: Emits a message to the observer. This might be handy if you use RefenaTracingPage.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifier<N extends BaseNotifier<T>, T>(NotifyableProvider<N, T> provider) → N: Returns the notifier of a NotifierProvider.
override
read<N extends BaseNotifier<T>, T, R>(Watchable<N, T, R> watchable) → R: Returns the actual value of a Provider.
override
redux<N extends BaseReduxNotifier<T>, T>(ReduxProvider<N, T> provider) → Dispatcher<N, T>: Get a proxy class to dispatch actions to a ReduxNotifier.
override
set(ProviderOverride<BaseNotifier, dynamic> override) → FutureOr<void>: Overrides a provider with a new value. This allows for overrides happening after the container was created.
override
stream<N extends BaseNotifier<T>, T>(BaseProvider<N, T> provider) → Stream<NotifierEvent<T>>: Listen for changes to a provider.
override
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.

Operators

operator ==(Object other) → bool: The equality operator.

Static Properties

defaultRef ↔ Ref: If you are unable to access the ref for whatever reason, there is a pragmatic solution for that. This is considered bad practice and should only be used as a last resort.
getter/setter pair

Static Methods

getPlatformHint() → PlatformHint: Returns the PlatformHint for the current platform. This type is used to represent the platform type without depending on Flutter or dart:io.
