FuchsiaViewConnection class

*[<Null safety>](https://dart.dev/null-safety)*

Defines a thin wrapper around FuchsiaViewController.

Its primary purpose is to hold on to ViewHolderToken for the lifetime of the view controller, since FuchsiaViewController is agnostic to all Fuchsia data types. (Eventually, FuchsiaView and FuchsiaViewController will be moved to Flutter framework, which cannot have Fuchsia data types.)

Constructors

FuchsiaViewConnection (dynamic viewHolderToken, {dynamic viewRef, FuchsiaViewConnectionCallback? onViewConnected, FuchsiaViewConnectionCallback? onViewDisconnected, FuchsiaViewConnectionStateCallback? onViewStateChanged, bool usePointerInjection = false, bool useFlatland = false})

Constructor.

FuchsiaViewConnection.flatland (dynamic viewportCreationToken, {dynamic viewRef, FuchsiaViewConnectionCallback? onViewConnected, FuchsiaViewConnectionCallback? onViewDisconnected, FuchsiaViewConnectionStateCallback? onViewStateChanged, bool usePointerInjection = false, bool useFlatland = true})

Properties

connected → bool

Returns true when platform view is connected.
read-only, inherited

hashCode → int

The hash code for this object.
read-only, inherited

hostViewRef → dynamic

read-only

onPointerEvent → FuchsiaPointerEventsCallback?

Callback when pointer events are dispatched on top of child view.
final, inherited

onViewConnected → FuchsiaViewConnectionCallback?

Callback when the connection to child's view is connected to view tree.
final, inherited

onViewDisconnected → FuchsiaViewConnectionCallback?

Callback when the child's view is disconnected from view tree.
final, inherited

onViewStateChanged → FuchsiaViewConnectionStateCallback?

Callback when the child view's state changes.
final, inherited

pointerInjector → PointerInjector

Returns the PointerInjector instance used by this connection.
read-only

runtimeType → Type

A representation of the runtime type of the object.
read-only, inherited

useFlatland → bool

final

usePointerInjection → bool

Set to true if pointer injection into child views should be enabled. This requires the view's ViewRef to be set during construction.
final

viewHolderToken → dynamic

The Gfx view tree token when the view is attached.
final

viewId → int

The raw value of the ViewHolderToken or ViewportCreationToken where this view is attached.
final, inherited

viewport → dynamic

Returns the viewport rect of the child view in parent's coordinates.
read-only, inherited

viewportCreationToken → dynamic

The Flatland token when the view is attached.
final

viewRef → dynamic

The handle to the view used for requestFocus calls.
final

whenConnected → Future

The future that completes when the platform view is connected.

Methods

clearFocus() Future<void>

inherited

connect({bool hitTestable = true, bool focusable = true, dynamic viewOcclusionHint = Rect.zero}) Future<void>

Connects to the platform view given it's viewId.
inherited

dispatchPointerEvent(dynamic event) Future<void>

Dispatch pointer events for the child view. This MUST NOT be called directly.
inherited

dispose() Future<void>

Dispose relevant resources when the view is take OffStage by Flutter.
inherited

noSuchMethod(Invocation invocation) dynamic

Invoked when a non-existent method or property is accessed.
inherited

onPointerInjectionError() void
requestFocus([int _ = 0]) Future<void>

Requests that focus be transferred to the remote Scene represented by this connection. This method is the point at which focus handling for flatland diverges. In Flatland, the Flutter engine holds the ViewRef and does not provide it to dart code, so we must refer to the child view by viewId instead
override

requestFocusById(int viewId) Future<void>

Requests that focus be transferred to the child view referred to by viewId. Note that this method should only be used with the Flatland API
inherited

toString() String

A string representation of this object.
inherited

update({bool focusable = true, bool hitTestable = true, dynamic viewOcclusionHint = Rect.zero}) Future<void>

Updates properties on the platform view given it's viewId.
inherited

Operators

operator ==(Object other) bool

The equality operator.
