struct	CpuUsageInfo
	CPU usage stats. num_threads is the number of threads owned by the process. It is to be noted that this is not per shell, there can be multiple shells within the process. total_cpu_usage is the percentage (between [0, 100]) cpu usage of the application. This is across all the cores, for example an application using 100% of all the core will report total_cpu_usage as 100, if it has 100% across 2 cores and 0% across the other cores, embedder must report total_cpu_usage as 50.

class	DartVM
	Describes a running instance of the Dart VM. There may only be one running instance of the Dart VM in the process at any given time. The Dart VM may be created and destroyed on any thread. Typically, the first Flutter shell instance running in the process bootstraps the Dart VM in the process as it starts up. This cost is borne on the platform task runner of that first Flutter shell. When the last Flutter shell instance is destroyed, the VM is destroyed as well if all shell instances were launched with the Settings::leak_vm flag set to false. If there is any shell launch in the process with leak_vm set to true, the VM is never shut down in the process. When the VM is shutdown, the cost of the shutdown is borne on the platform task runner of the last shell instance to be shut down. More...

	Interface implemented by all platform surfaces that can present a metal backing store to the "screen". The GPU surface abstraction (which abstracts the client rendering API) uses this delegation pattern to tell the platform surface (which abstracts how backing stores fulfilled by the selected client rendering API end up on the "screen" on a particular platform) when the rasterizer needs to allocate and present the software backing store. More...

class	ImageFilterMutation
class	ImageGenerator
	The minimal interface necessary for defining a decoder that can be used for both single and multi-frame image decoding. Image generators can also optionally support decoding into a subscaled buffer. Implementers of ImageGenerator regularly keep internal state which is not thread safe, and so aliasing and parallel access should never be done with ImageGenerators. More...
class	ImageGeneratorRegistry
	Keeps a priority-ordered registry of image generator builders to be used when decoding images. This object must be created, accessed, and collected on the UI thread (typically the engine or its runtime controller). More...

class	IOManager
class	IOSContext
	Manages the lifetime of the on-screen and off-screen rendering contexts on iOS. On-screen contexts are used by Flutter for rendering into the surface. The lifecycle of this context may be tied to the lifecycle of the surface. On the other hand, the lifecycle of the off-screen context it tied to that of the platform view. This one object used to manage both context because GPU handles may need to be shared between the two context. To achieve this, context may need references to one another at creation time. This one object manages the creation, use and collection of both contexts in a client rendering API agnostic manner. More...

class	IsolateConfiguration
	An isolate configuration is a collection of snapshots and asset managers that the engine will use to configure the isolate before invoking its root entrypoint. The set of snapshots must be sufficient for the engine to move the isolate from the |DartIsolate::Phase::LibrariesSetup| phase to the |DartIsolate::Phase::Ready| phase. Note that the isolate configuration will not be collected till the isolate tied to the configuration as well as any and all child isolates of that isolate are collected. The engine may ask the configuration to prepare multiple isolates. All subclasses of this class must be thread safe as the configuration may be created, collected and used on multiple threads. Usually these threads are engine or VM managed so care must be taken to ensure that subclasses do not reference any thread local state. More...

class	PlatformMessageResponseDarwin
class	PlatformView
	Platform views are created by the shell on the platform task runner. Unless explicitly specified, all platform view methods are called on the platform task runner as well. Platform views are usually sub-classed on a per platform basis and the bulk of the window system integration happens using that subclass. Since most platform window toolkits are usually only safe to access on a single "main" thread, any interaction that requires access to the underlying platform's window toolkit is routed through the platform view associated with that shell. This involves operations like settings up and tearing down the render surface, platform messages, interacting with accessibility features on the platform, input events, etc. More...

bool	EnableTracingIfNecessary (const Settings &vm_settings)
	Enables tracing in the process so that JIT mode VMs may be launched. Explicitly enabling tracing is not required on all platforms. On platforms where it is not required, calling this method will return true. If tracing is required but cannot be enabled, it is the responsibility of the caller to display the appropriate error message to the user as subsequent attempts to launch the VM in JIT mode will cause process termination.
TracingResult	GetTracingResult ()
	Returns if a tracing check has been performed and its result. To enable tracing, the Settings object used to launch the VM is required. Components may want to display messages based on the result of a previous tracing check without actually having the settings object. This accessor can be used instead.

AppLifecycleState

enum class flutter::AppLifecycleState

strong

These constants describe the possible lifecycle states of the application. They must be kept up to date with changes in the framework's AppLifecycleState enum. They are passed to the embedder's |SetLifecycleState| function.

States not supported on a platform will be synthesized by the framework when transitioning between states which are supported, so that all implementations share the same state machine.

Here is the state machine:

+-----------+                               +-----------+
| detached  |------------------------------>|  resumed  |
+-----------+                               +-----------+
     ^                                              ^
     |                                              |
     |                                              v
+-----------+        +--------------+       +-----------+
| paused    |<------>|    hidden    |<----->|  inactive |
+-----------+        +--------------+       +-----------+

Enumerator
kDetached	Corresponds to the Framework's AppLifecycleState.detached: The initial state of the state machine. On Android, iOS, and web, also the final state of the state machine when all views are detached. Other platforms do not re-enter this state after initially leaving it.
kResumed	Corresponds to the Framework's AppLifecycleState.resumed: The nominal "running" state of the application. The application is visible, has input focus, and is running.
kInactive	Corresponds to the Framework's AppLifecycleState.inactive: At least one view of the application is visible, but none have input focus. The application is otherwise running normally.
kHidden	Corresponds to the Framework's AppLifecycleState.hidden: All views of an application are hidden, either because the application is being stopped (on iOS and Android), or because it is being minimized or on a desktop that is no longer visible (on desktop), or on a tab that is no longer visible (on web).
kPaused	Corresponds to the Framework's AppLifecycleState.paused: The application is not running, and can be detached or started again at any time. This state is typically only entered into on iOS and Android.

DlBlendMode

enum class flutter::DlBlendMode

strong

A enum define the blend mode. Blends are operators that take in two colors (source, destination) and return a new color. Many of these operate the same on all 4 components: red, green, blue, alpha. For these, we just document what happens to one component, rather than naming each one separately. Different color types might have different representations for color components: 8-bit: 0..255 6-bit: 0..63 5-bit: 0..31 4-bit: 0..15 floats: 0...1 The comments are expressed as if the component values are always 0..1 (floats). For brevity, the documentation uses the following abbreviations s : source d : destination sa : source alpha da : destination alpha Results are abbreviated r : if all 4 components are computed in the same manner ra : result alpha component rc : result "color": red, green, blue components

CreateEmbedderTaskRunner()

static std::pair< bool, fml::RefPtr< EmbedderTaskRunner > > flutter::CreateEmbedderTaskRunner ( const FlutterTaskRunnerDescription *  description )

static

Attempts to create a task runner from an embedder task runner description. The first boolean in the pair indicate whether the embedder specified an invalid task runner description. In this case, engine launch must be aborted. If the embedder did not specify any task runner, an engine managed task runner and thread must be selected instead.

Parameters

[in]

description

The description

Returns

A pair that returns if the embedder has specified a task runner (null otherwise) and whether to terminate further engine launch.

EnableTracingIfNecessary()

bool flutter::EnableTracingIfNecessary ( const Settings &  vm_settings )

inline

Enables tracing in the process so that JIT mode VMs may be launched. Explicitly enabling tracing is not required on all platforms. On platforms where it is not required, calling this method will return true. If tracing is required but cannot be enabled, it is the responsibility of the caller to display the appropriate error message to the user as subsequent attempts to launch the VM in JIT mode will cause process termination.

This method may be called multiple times and will return the same result. There are no threading restrictions.

Parameters

[in]

vm_settings

The settings used to launch the VM.

Returns

If tracing was enabled.

kImpellerRepaintRatio

constexpr float flutter::kImpellerRepaintRatio = 0.7f

constexpr

The max ratio of pixel width or height to size that is dirty which results in a partial repaint.

Performing a partial repaint has a small overhead - Impeller needs to allocate a fairly large resolve texture for the root pass instead of using the drawable texture, and a final blit must be performed. At a minimum, if the damage rect is the entire buffer, we must not perform a partial repaint. Beyond that, we could only experimentally determine what this value should be. From looking at the Flutter Gallery, we noticed that there are occassionally small partial repaints which shave off trivial numbers of pixels.
