Functions ¶
func CountFlutterEngines ¶
func CountFlutterEngines() int
CountFlutterEngines return the number of engines registered in this embedder.
func FlutterEngineFlushPendingTasksNow ¶
func FlutterEngineFlushPendingTasksNow()
FlutterEngineFlushPendingTasksNow flush tasks on a message loop not controlled by the Flutter engine. deprecated soon.
Types ¶
type FlutterEngine ¶
type FlutterEngine struct {
// Flutter Engine.
Engine C.FlutterEngine
// Necessary callbacks for rendering.
FMakeCurrent func(v unsafe.Pointer) bool
FClearCurrent func(v unsafe.Pointer) bool
FPresent func(v unsafe.Pointer) bool
FFboCallback func(v unsafe.Pointer) int32
FMakeResourceCurrent func(v unsafe.Pointer) bool
// platform message callback.
FPlatfromMessage func(message *PlatformMessage, window unsafe.Pointer) bool
// Engine arguments
AssetsPath string
IcuDataPath string
// contains filtered or unexported fields
}
FlutterEngine corresponds to the C.FlutterEngine with his associated callback's method.
func FlutterEngineByIndex ¶
func FlutterEngineByIndex(index int) *FlutterEngine
FlutterEngineByIndex returns an existing FlutterEngine by its index in this embedder.
func NewFlutterEngine ¶
func NewFlutterEngine() *FlutterEngine
NewFlutterEngine creates an empty FlutterEngine and assigns it an index for global lookup.
func (*FlutterEngine) Index ¶
func (flu *FlutterEngine) Index() int
Index returns the index of the engine in the global flutterEngines slice
func (*FlutterEngine) Run ¶
func (flu *FlutterEngine) Run(window uintptr, vmArgs []string) Result
Run launches the Flutter Engine in a background thread.
func (*FlutterEngine) SendPlatformMessage ¶
func (flu *FlutterEngine) SendPlatformMessage(Message *PlatformMessage) Result
SendPlatformMessage is used to send a PlatformMessage to the Flutter engine.
func (*FlutterEngine) SendPlatformMessageResponse ¶
func (flu *FlutterEngine) SendPlatformMessageResponse( responseTo *PlatformMessage, data []byte, ) Result
SendPlatformMessageResponse is used to send a message to the Flutter side using the correct ResponseHandle!
func (*FlutterEngine) SendPointerEvent ¶
func (flu *FlutterEngine) SendPointerEvent(Event PointerEvent) Result
SendPointerEvent is used to send an PointerEvent to the Flutter engine.
func (*FlutterEngine) SendWindowMetricsEvent ¶
func (flu *FlutterEngine) SendWindowMetricsEvent(Metric WindowMetricsEvent) Result
SendWindowMetricsEvent is used to send a WindowMetricsEvent to the Flutter Engine.
func (*FlutterEngine) Shutdown ¶
func (flu *FlutterEngine) Shutdown() Result
Shutdown stops the Flutter engine.
type Message ¶
type Message struct {
// Describe the method
Method string `json:"method"`
// Actual datas
Args json.RawMessage `json:"args"`
}
Message is the json content of a PlatformMessage
type PlatformMessage ¶
type PlatformMessage struct {
Channel string
Message Message
ResponseHandle *C.FlutterPlatformMessageResponseHandle
}
PlatformMessage represents a `MethodChannel` serialized with the `JSONMethodCodec` TODO Support for `StandardMethodCodec`
type PointerEvent ¶
type PointerEvent struct {
Phase PointerPhase
Timestamp int64
X float64
Y float64
}
PointerEvent represents the position and phase of the mouse at a given time.
type PointerPhase ¶
type PointerPhase int32
PointerPhase corresponds to the C.enum describing phase of the mouse pointer.
const ( KCancel PointerPhase = C.kCancel KUp PointerPhase = C.kUp KDown PointerPhase = C.kDown KMove PointerPhase = C.kMove )
Values representing the mouse phase.
type Result ¶
type Result int32
Result corresponds to the C.enum retuned by the shared flutter library whenever we call it.
const ( KSuccess Result = C.kSuccess KInvalidLibraryVersion Result = C.kInvalidLibraryVersion KInvalidArguments Result = C.kInvalidArguments )
Values representing the status of an Result.
type WindowMetricsEvent ¶
WindowMetricsEvent represents a window's resolution.
