Detailed Description

The deprecated FlutterHeadlessDartRunner runs Flutter Dart code with a null rasterizer, and no native drawing surface. It is appropriate for use in running Dart code e.g. in the background from a plugin.

Most callers should prefer using FlutterEngine directly; this interface exists for legacy support.

Method Documentation

init

- (instancetype) init

Not recommended for use - will initialize with a default label ("io.flutter.headless") and the default FlutterDartProject.

Reimplemented from FlutterEngine.

initWithName:project:

- (instancetype) initWithName:		(NSString *)	labelPrefix
project:		(FlutterDartProject *)	projectOrNil

Initialize this FlutterHeadlessDartRunner with a FlutterDartProject.

If the FlutterDartProject is not specified, the FlutterHeadlessDartRunner will attempt to locate the project in a default location.

A newly initialized engine will not run the FlutterDartProject until either -runWithEntrypoint: or -runWithEntrypoint:libraryURI is called.

Parameters

labelPrefix	The label prefix used to identify threads for this instance. Should be unique across FlutterEngine instances
projectOrNil	The FlutterDartProject to run.

Reimplemented from FlutterEngine.

initWithName:project:allowHeadlessExecution:

- (instancetype) initWithName:		(NSString *)	labelPrefix
project:		(FlutterDartProject *)	projectOrNil
allowHeadlessExecution:		(BOOL)	allowHeadlessExecution

Initialize this FlutterHeadlessDartRunner with a FlutterDartProject.

If the FlutterDartProject is not specified, the FlutterHeadlessDartRunner will attempt to locate the project in a default location.

A newly initialized engine will not run the FlutterDartProject until either -runWithEntrypoint: or -runWithEntrypoint:libraryURI is called.

Parameters

labelPrefix	The label prefix used to identify threads for this instance. Should be unique across FlutterEngine instances
projectOrNil	The FlutterDartProject to run.
allowHeadlessExecution	Must be set to YES.

Reimplemented from FlutterEngine.

initWithName:project:allowHeadlessExecution:restorationEnabled:

- (instancetype) initWithName:		(NSString *)	labelPrefix
project:		(FlutterDartProject *)	projectOrNil
allowHeadlessExecution:		(BOOL)	allowHeadlessExecution
restorationEnabled:		(BOOL)	NS_DESIGNATED_INITIALIZER

Initialize this FlutterHeadlessDartRunner with a FlutterDartProject.

If the FlutterDartProject is not specified, the FlutterHeadlessDartRunner will attempt to locate the project in a default location.

A newly initialized engine will not run the FlutterDartProject until either -runWithEntrypoint: or -runWithEntrypoint:libraryURI is called.

Parameters

labelPrefix	The label prefix used to identify threads for this instance. Should be unique across FlutterEngine instances
projectOrNil	The FlutterDartProject to run.
allowHeadlessExecution	Must be set to YES.
restorationEnabled	Must be set to NO.

Reimplemented from FlutterEngine.
