Struct InertPlatform 

pub struct InertPlatform;

Platform for hand-pumped tests.

Trait Implementations

impl Platform for InertPlatform

fn target_platform(&self) -> TargetPlatform

Android, which is what Flutter’s own test binding defaults debugDefaultTargetPlatform to: a bare App has no host to speak of, and a deterministic answer beats the machine’s.

fn request_frame(&self)

Requests one isolate frame at the host’s next appropriate opportunity.

fn now(&self) -> Instant

The host clock used for frame and timer timestamps.

fn wake_at(&self, _deadline: Instant)

Asks the host to wake the application at deadline.

fn views(&self) -> Vec<ViewRef>

Current host-provided views.

fn view(&self, _id: ViewId) -> Option<ViewRef>

Looks up a current host-provided view.

fn implicit_view(&self) -> Option<ViewRef>

The stable implicit view, when this embedding provides one.

fn request_view_focus_change( &self, view_id: ViewId, state: ViewFocusState, direction: ViewFocusDirection, )

Flutter PlatformDispatcher.requestViewFocusChange: asks the host to move view focus. A host without native focus support ignores the request.

fn locales(&self) -> Vec<Locale>

The full system-reported supported locales of the device (Flutter PlatformDispatcher.locales), in order of preference; empty until the host reports them.

fn set_application_locale(&self, locale: &Locale)

Tells the host which locale the application resolved to (Flutter PlatformDispatcher.setApplicationLocale); the default drops it.

fn platform_brightness(&self) -> Brightness

The platform’s light/dark preference (Flutter PlatformDispatcher.platformBrightness).

fn default_route_name(&self) -> String

The route the application was started with (Flutter PlatformDispatcher.defaultRouteName).

fn font_source(&self) -> Option<Box<dyn FontSource>>

The platform’s own font lookup: faces by family name and by codepoint, the way Flutter’s engine asks the OS. None for a host without one; text then shapes only against fonts the application registers.

fn open_image_codec(&self, bytes: Arc<[u8]>) -> ImageCodecFuture

Open an encoded image, answering with a codec for its frames.

fn import_pixels(&self, pixels: PixelBuffer) -> Option<Image>

An image from pixels the app already holds, with no codec in between: Flutter’s decodeImageFromPixels. None when the host has no renderer to put it on yet.

fn windowing_owner(&self) -> Option<Rc<dyn WindowingOwner>>

The host’s window maker, for an app that opens windows of its own. None, the default, where the implicit view is the only one there can be: mobile and the web.

fn clipboard(&self) -> Option<&dyn Clipboard>

The system clipboard, or None where the host has none.

fn system_chrome(&self) -> Option<&dyn SystemChrome>

The system UI drawn around the app, or None where the host has none.

fn haptics(&self) -> Option<&dyn Haptics>

Haptic feedback on the device, or None where the host has none.

fn system_context_menu(&self) -> Option<&dyn SystemContextMenu>

The system’s own menu over a text selection, or None where the host has none.

fn popup_menus(&self) -> Option<&dyn PopupMenus>

Native pop-up menus shown at the pointer, or None where the host has none.

fn text_services(&self) -> Option<&dyn TextServices>

The system services a selection toolbar offers, or None where the host has none.

fn mouse_cursor(&self) -> Option<&dyn MouseCursor>

The system cursor shown for a pointing device, or None where the host has none.

fn restoration(&self) -> Option<&dyn Restoration>

Application state kept across relaunches, or None where the host has none.
