Public Member Functions inherited from flutter::IsolateConfiguration
	IsolateConfiguration ()
	Create an isolate configuration. This has no threading restrictions. More...

virtual	~IsolateConfiguration ()
	Destroys an isolate configuration. This has no threading restrictions and may be collection of configurations may occur on any thread (and usually happens on an internal VM managed thread pool thread). More...

bool	PrepareIsolate (DartIsolate &isolate)
	When an isolate is created and sufficiently initialized to move it into the `DartIsolate::Phase::LibrariesSetup` phase, this method is invoked on the isolate to then move the isolate into the `DartIsolate::Phase::Ready` phase. Then isolate's main entrypoint is then invoked to move it into the `DartIsolate::Phase::Running` phase. This method will be called each time the root isolate is launched (which may be multiple times in cold-restart scenarios) as well as one each for any child isolates referenced by that isolate. More...

Additional Inherited Members
Static Public Member Functions inherited from flutter::IsolateConfiguration
static std::unique_ptr< IsolateConfiguration >	InferFromSettings (const Settings &settings, const std::shared_ptr< AssetManager > &asset_manager=nullptr, const fml::RefPtr< fml::TaskRunner > &io_worker=nullptr, IsolateLaunchType launch_type=IsolateLaunchType::kNewGroup)
	Attempts to infer the isolate configuration from the `Settings` object. If the VM is configured for AOT mode, snapshot resolution is attempted with predefined symbols present in the currently loaded process. In JIT mode, Dart kernel file resolution is attempted in the assets directory. If an IO worker is specified, snapshot resolution may be attempted on the serial worker task runner. The worker task runner thread must remain valid and running till after the shell associated with the engine used to launch the isolate for which this run configuration is used is collected. More...

static std::unique_ptr< IsolateConfiguration >	CreateForAppSnapshot ()
	Creates an AOT isolate configuration using snapshot symbols present in the currently loaded process. These symbols need to be given to the Dart VM on bootstrap and hence have already been resolved. More...

static std::unique_ptr< IsolateConfiguration >	CreateForKernelList (std::vector< std::future< std::unique_ptr< const fml::Mapping > > > kernel_pieces)
	Creates a JIT isolate configuration using a list of futures to snapshots defining the ready isolate state. In environments where snapshot resolution is extremely expensive, embedders attempt to resolve snapshots on worker thread(s) and return the future of the promise of snapshot resolution to this method. That way, snapshot resolution begins well before isolate launch is attempted by the engine. More...

static std::unique_ptr< IsolateConfiguration >	CreateForKernel (std::unique_ptr< const fml::Mapping > kernel)
	Creates a JIT isolate configuration using the specified snapshot. This is a convenience method for the `CreateForKernelList` method that takes a list of futures to Dart kernel snapshots. More...

static std::unique_ptr< IsolateConfiguration >	CreateForKernelList (std::vector< std::unique_ptr< const fml::Mapping > > kernel_pieces)
	Creates a JIT isolate configuration using the specified snapshots. This is a convenience method for the `CreateForKernelList` method that takes a list of futures to Dart kernel snapshots. More...
