Crate inset_embedder

Expand description

Flutter’s dart:ui: host traits (Platform, View) and value types (Offset, Color, Canvas, Paint, Shadow).

The framework depends on this crate. This crate does not depend on the framework. Hosts implement Platform and View, and invoke EmbedderClient on the client the start closure returns. They do not name App.

Structs§

AppExitReply: The answer to one request to exit, which the host made through EmbedderClient::request_app_exit: Flutter’s reply to System.requestAppExit. It is answered once; dropped unanswered, it answers AppExitResponse::Exit, since an application that lets go of the question has nothing to keep.

ContainerLayer: flow’s ContainerLayer and the containers derived from it: children in paint order, the bottom-most first, under one effect.
CopyOptions: How a copy is to be treated. Each option names what it is for, and a host whose system lacks it leaves it out, but for the expiry, which a host does itself where the system cannot.
CopyRequest: Where the user’s copy or cut is written: the clipboard, as the platform lets the user’s own copy write it.
Cue: One subtitle or caption to show: Media3’s Cue.

Image: Image is a cheap-to-clone handle to an immutable GPU image.
ImageFrame: One decoded frame, prepared and ready to draw. Flutter dart:ui FrameInfo.

RestorationUpdate: What the host answers when the framework asks for the restoration data it stored.
SaveOptions: How to ask where to save a file.
Scene: Flutter Scene: what SceneBuilder::build produces and crate::View::present takes, the root of one frame’s layer tree, flow’s LayerTree. The view knows its own size.
SceneBuilder: Builds a Scene containing the given visuals.
Screen: A monitor: where it is (the frames, for placing windows) and what drawing on it needs (Flutter’s Display: id, devicePixelRatio, refreshRate; Display.size is the frame’s size at scale).
ScreenId: Names a screen: Flutter’s Display.id, which the embedder API calls a FlutterEngineDisplayId. Each host numbers its screens its own way; a screen keeps its number while it stays connected.
SeekTolerance: How far from its target a seek may land, before and after it, for the system to land sooner: Apple’s tolerances, Media3’s SeekParameters. A system that seeks only exactly keeps any tolerance.

Typeface: Typeface is one face the platform matched: a font file, the face’s index in it, and how the platform names and styles that face.
Vector3: A three-dimensional vector.
VideoLayer: A video, drawn into rect in its container’s coordinates: Chromium’s cc::VideoLayer over its frame provider. The layer holds the reader, never a frame: whoever draws the scene asks the reader then for the frame of the moment the picture reaches the screen, so a frame is held only while it is on screen.
ViewConstraints: Immutable layout constraints for a view (dart:ui ViewConstraints).
ViewFocusEvent: An event for the engine to communicate view focus changes to the app. Flutter counterpart: ViewFocusEvent in dart:ui/platform_dispatcher.dart.

What the user copies is written, and what they pasted read, through the event, which may reach what the app’s own calls may not.
ColorFilter: A description of a color filter to apply when drawing a shape or compositing a layer with a particular Paint. A color filter is a function that takes two colors, and outputs one color. When applied during compositing, it is independently applied to each pixel of the layer being drawn before the entire layer is merged with the destination.
ColorSpace: The color space describes the colors that are available to an Image.
Content: One form’s content. A file, given or promised, is keyed by the type of what is in it, and a reader finds it as URI_LIST.

GenericCaptionFont: The kinds of font caption standards name: Windows’ ClosedCaptionStyle and Apple’s MACaptionAppearanceFontStyle, their defaults aside.
HapticFeedbackType: The kind of haptic feedback to play.
HardwareBuffer: A platform with no host that composites: no buffer can exist, so CompositionLayer::present cannot be called, and Platform::compositor answers None.
ImageDecodeError: Why an image could not be read. Flutter reports these as an exception on the codec future.
ImageFilter: A filter operation to apply to a raster image.
ImageRepetition: How an animation repeats once it has played through.

PlayerErrorKind: The kind of a player’s failure, which an app words for its user and acts on: the web’s MediaError and Windows’ MediaPlayerError share the first three, and Apple’s AVError and Media3’s error codes fall into them.
PlayerStatus: How far a player got with its media.
PointerChange: How the pointer has changed since the last report.
PointerDeviceKind: The kind of pointer device.
PointerSignalKind: The kind of pointer signal event.

ViewFocusDirection: Represents the direction in which focus transitioned across views.
ViewFocusState: Represents the focus state of a given view.

Constants§

K_TEXT_HEIGHT_NONE: A TextStyle.height value that indicates the text span should take the height defined by the font, which may not be exactly the height of fontSize.
URI_LIST: The type a pasted file is read in: its file: URL, one line per file (RFC 2483), as every system carries a file on its clipboard as a reference.

Traits§

AppExit: The application quitting itself: the System.exitApplication message of Flutter’s SystemChannels.platform, for a required exit. A cancelable exit never reaches the host: the framework asks its own listeners first (ServicesBinding::exit_application), and quits here once they agree.
AttachedMenu: A tray icon’s menu the system opens by itself.
CameraDevice: A camera the app opened, controlled on the app’s main thread: Camera2’s CameraDevice. A session started on it runs on after it is dropped.
Cameras: The system’s cameras, or None from Platform::cameras where it has none.
CanvasText: Paragraph drawing on a Canvas (Dart’s Canvas.drawParagraph).
CaptionSettings: The user’s system-wide caption settings: Apple’s MACaptionAppearance, Android’s CaptioningManager, Windows’ ClosedCaptionProperties.
CaptureSession: A camera running for the app, controlled on the app’s main thread. Dropped, it stops for the app: its preview leaves the layer it showed on, and its reader reads nothing more.
Clipboard: The system clipboard. Every call answers later, as a host may have to ask its user, or another process, first.
CompositionLayer: One layer of the compositor’s tree. Every method may be called from any thread.
Compositor: The host’s compositor, as an app reaches it.
DataTransferItem: One item on the clipboard, as it was when the clipboard was listed, or of a drag (DragReport): the web’s DataTransferItem, the item its clipboard events and its drag and drop both hand over.
Dispatcher: The host’s threads as any thread reaches them: the two things the framework asks of them. gpui’s PlatformDispatcher. Flutter’s embedder API has the first as post_task_callback, with its target time, and keeps the second — the engine’s own worker threads — to itself.
DockMenu: The menu of the app’s Dock icon: macOS’s.
EmbedderClient: Complete frames and typed view lifecycle notifications.
FileDialogs: The system’s file dialogs. parent is the view whose window a dialog belongs to, which the system shows it on, as a sheet where it has them (macOS); without one it stands alone.
FileHandle: A picked file the system gives no path for, read and written at any offset.
FileSink: Where a promised file’s bytes go, in order: the host’s, which writes them into the file where the receiver chose, as NSFilePromiseProvider writes at the receiver’s URL.
FileStream: A picked file that can only be read through, once, start to end.
FileWriter: Writing to a picked file.
FolderHandle: A picked folder the system gives no path for: what is in it, opened by name, and, when the pick is writable, files and folders made in it. What it opens is writable when it is.
FontManager: FontManager is the platform’s font lookup, in the shape of Skia’s SkFontMgr.
FontSource: FontSource locates fonts that are not already registered.
Haptics: Flutter’s HapticFeedback.
HostWindow: The window around a view the host puts on screen in a window the app may manage.
ImageCodec: One encoded image, opened and ready to give up its frames. Flutter dart:ui Codec.
MediaPlayer: One player, controlled on the app’s main thread. Dropped, it stops, and its picture goes nowhere: it leaves the layer it showed on, and its reader reads nothing more.
MenuAtIcon: A tray icon’s menu the app opens.
MenuBar: The app’s menu bar: macOS’s. Where the system has none, the platform answers None and the app draws its own.
NotificationPermission: The user’s permission to notify, as the system keeps it for the app and asks for it.
NotificationReplies: Typed replies, where the system takes them.
NotificationScheduling: Delivery at a later time, which the system holds whether or not the app runs.
Notifications: The system’s notifications.
Opener: The system’s way to open links and files in other apps.
Platform: The long-lived host object held by the application.
Players: The system’s players, or None from Platform::players where it has none.
PopupMenus: A menu the system opens at a point in a view, answered with the item chosen.
Restoration: Flutter’s restoration channel: state kept across relaunches.
Screens: The screens the app’s views are on: what drawing on each needs, as Flutter’s PlatformDispatcher.displays lists them, and where each is, for an app that places a window against something on them, such as an edge or its own icon, which Flutter’s Display has no place for. Positions are in the coordinates of HostWindow::frame: logical points from the top-left corner of the main screen, y growing down.
SystemChrome: Flutter’s SystemChrome: the system UI around the app.
SystemContextMenu: Flutter’s SystemContextMenu: the system’s own menu over a text selection.
TextInputHost: The host side of Flutter’s text input connection for one view.
TextServices: The text services a selection toolbar offers: Flutter’s LookUp, SearchWeb and Share platform-channel calls.
TrayIcon: An icon in the system’s tray, removed when dropped. What it offers is what its system allows; its conventions, such as a menu opened on a right click, are the app’s or the framework’s.
TrayIcons: The app’s icons in the system’s tray: macOS’s status items, Windows’ notification area, Linux’s StatusNotifierItems.
VideoFrame: One picture of a video as the system hands it out, as WebCodecs’ VideoFrame. It holds its slot in the decoder’s pool until it, and every texture made of it, are dropped.
VideoFrameReader: The pictures of the one source a reader is given to, read from any thread as they are drawn. It takes one source at a time, as Android’s ImageReader takes one producer: given to a second while the first still feeds it, it is refused, and the second sends its frames nowhere. A reader keeps no frame for later: one not read before the next arrives is dropped.
VideoFrameReaders: The system’s frame readers, or None from Platform::video_frame_readers where it hands out no frames.
View: A stable handle to one host-provided view.
ViewEmbedder: What the app uses to embed views of its own, as Flutter’s embedder does: adding one on a layer it makes and places, giving its metrics and its being in sight, handing it input, and removing it (Platform::view_embedder).
ViewHost: What one view asks of the system, provided by whoever hosts the view: a window’s view gets its window’s. Chromium’s RenderWidgetHostView and Android’s SurfaceControlViewHost are this piece; where Flutter’s embedders take the same requests on the platform as a whole, through SystemChannels.textInput, SystemChannels.mouseCursor and PlatformDispatcher.requestViewFocusChange, here each view’s own host takes them.
VsyncObserver: What a VsyncWaiter calls at the refresh it was asked for.
VsyncWaiter: Flutter’s VsyncWaiter, for any screen.

compose: Composes a matrix from translation, rotation and scale.
decompose: Decomposes matrix into its translation, rotation and scale components.
default_font_families: Flutter txt::GetDefaultFontFamilies() of the engine built for os, from that OS’s file (txt/platform_mac.mm, platform_linux.cc, …): the families text is drawn in when its style names none, first match first.
file_uri_path: The path a file: URI names on this system, its percent-encoding decoded; None for another URI, one on another host, or one that does not decode.
flattened_ops: The picture’s operations in replay order with every embedded list’s following its embedding op, for a test or a diagnostic that asks what a scene draws regardless of how its layers nested it.

set_default_font_manager: Flutter skia::textlayout::FontCollection::setDefaultFontManager: register the faces of families, the platform’s default families, as the collection’s fallback chain, then keep source for later lookups.
slices: The scene’s slices and composition layers, in paint order: what Flutter’s embedder hands its compositor as FlutterLayers, before any slice is rendered. frame_image answers the image of the frame each video’s reader shows in this draw, None for one with nothing to show; a host without video answers None for all.
transform3: Transforms a point as a 3-vector, with no perspective division.
