Functions ¶
func EngineFlushPendingTasksNow ¶
func EngineFlushPendingTasksNow()
EngineFlushPendingTasksNow flush tasks on a message loop not controlled by the Flutter engine. deprecated soon.
Types ¶
type ArgsAppSwitcherDescription ¶
type ArgsAppSwitcherDescription struct {
Label string `json:"label"`
PrimaryColor int64 `json:"primaryColor"`
}
ArgsAppSwitcherDescription Args content
type ArgsEditingState ¶
type ArgsEditingState struct {
Text string `json:"text"`
SelectionBase int `json:"selectionBase"`
SelectionExtent int `json:"selectionExtent"`
SelectionAffinity string `json:"selectionAffinity"`
SelectionIsDirectional bool `json:"selectionIsDirectional"`

ComposingExtent int `json:"composingExtent"`
}
ArgsEditingState Args content
type EngineOpenGL ¶
type EngineOpenGL 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
PixelRatio float64
AssetsPath *CharExportedType
IcuDataPath *CharExportedType
}
EngineOpenGL corresponds to the C.FlutterEngine with his associated callback's method.
func (*EngineOpenGL) EngineSendPlatformMessage ¶
func (flu *EngineOpenGL) EngineSendPlatformMessage(Message PlatformMessage) Result
EngineSendPlatformMessage is used to send a PlatformMessage to the Flutter engine.
func (*EngineOpenGL) EngineSendPointerEvent ¶
func (flu *EngineOpenGL) EngineSendPointerEvent(Event PointerEvent) Result
EngineSendPointerEvent is used to send an PointerEvent to the Flutter engine.
func (*EngineOpenGL) EngineSendWindowMetricsEvent ¶
func (flu *EngineOpenGL) EngineSendWindowMetricsEvent(Metric WindowMetricsEvent) Result
EngineSendWindowMetricsEvent is used to send a WindowMetricsEvent to the Flutter Engine.
func (*EngineOpenGL) Run ¶
func (flu *EngineOpenGL) Run(window uintptr, vmArgs []string) Result
Run launches the Flutter Engine in a background thread.
func (*EngineOpenGL) Shutdown ¶
func (flu *EngineOpenGL) 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 *platformMessageResponseHandle
}
PlatformMessage represents a message from or to the Flutter Engine (and thus the dart code)
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.
