Constructors

Aspect(A fn(T), [Key? key])

Create an InheritableAspect of T that depends on Inheritable of T for any changes of A produced by fn.

const

Aspect.patchable({required AspectPatch<A, T> patch, required A transform(T), Key? key})

Create an aspect A of T using transform, which can optionaly be later patched using patch.

const

Properties

debugLabel → String?

Debug-mode label for this aspect

final, inherited

didUpdateWidgetImpl → DidUpdateWidget<T>

no setter

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

Uniquely identifying local key for this aspect. This used by hashCode and ==. This allows InheritableAspect implementations to accept and hold closures in object instances and still have a unique object identity.

final

mapper → A Function(T)

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

clone({Key? key, A mapper(T)?, AspectPatch<A, T>? patch, DidUpdateWidget<T>? didUpdateWidget, DefaultInheritableAspectOfContext<A>? defaultValue}) → Aspect<A, T>

Create a new instance of this aspect with the specified fields replaced.

override

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

override

didUpdateWidget({required Inheritable<T> prev, required Inheritable<T> next}) → bool

Called by Inheritable of T when it decides to notify it's dependents. This is only called after Inheritable of T has been updated at least once. For the first time, aka "init" phase, satisfiedBy is called instead.

override

ensureHasKey({Key? fallback}) → InheritableAspect<T>

Ensure that this InheritableAspect has a valid key. This is to make sure aspects that are intended to behave differently using for same BuildContext don't override each other.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

of(BuildContext context, {bool rebuild = true, A? defaultValue}) → A?

Convenience method for when an InheritableAspect is already known.

override

patch(T value, A next) → T

Given a new A of T, return the patched T

override

satisfiedBy(Inheritable<T> inheritable) → bool

Specify whether given inheritable satisfies this aspect.

inherited

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

toStringShort() → String

A brief description of this object, usually just the runtimeType and the hashCode.

inherited

transform(T value) → A

Given value, transform it into usable form

override

Operators

operator ==(Object other) → bool

The equality operator.
