        public void addFirstFrameListener​(FlutterView.FirstFrameListener listener)
        Deprecated.

        public void removeFirstFrameListener​(FlutterView.FirstFrameListener listener)
        Deprecated.

      • enableBufferingIncomingMessages

        public void enableBufferingIncomingMessages()
        Deprecated.
        Description copied from interface: BinaryMessenger
        Enables the ability to queue messages received from Dart.

        This is useful when there are pending channel handler registrations. For example, Dart may be initialized concurrently, and prior to the registration of the channel handlers. This implies that Dart may start sending messages while plugins are being registered.

        Specified by:
        enableBufferingIncomingMessages in interface BinaryMessenger

      • disableBufferingIncomingMessages

        public void disableBufferingIncomingMessages()
        Deprecated.
        Description copied from interface: BinaryMessenger
        Disables the ability to queue messages received from Dart.

        This can be used after all pending channel handlers have been registered.

        Specified by:
        disableBufferingIncomingMessages in interface BinaryMessenger

      • disableTransparentBackground

        public void disableTransparentBackground()
        Deprecated.
        Reverts this back to the SurfaceView defaults, at the back of its window and opaque.

      • setInitialRoute

        public void setInitialRoute​(String route)
        Deprecated.

      • pushRoute

        public void pushRoute​(String route)
        Deprecated.

      • popRoute

        public void popRoute()
        Deprecated.

      • destroy

        public void destroy()
        Deprecated.

      • onGenericMotionEvent

        public boolean onGenericMotionEvent​(MotionEvent event)
        Deprecated.
        Invoked by Android when a generic motion event occurs, e.g., joystick movement, mouse hover, track pad touches, scroll wheel movements, etc.

        Flutter handles all of its own gesture detection and processing, therefore this method forwards all MotionEvent data from Android to Flutter.

        Overrides:
        onGenericMotionEvent in class View

      • onSizeChanged

        protected void onSizeChanged​(int width,

                             int oldWidth,
                             int oldHeight)
        Deprecated.
        Overrides:
        onSizeChanged in class View

        protected boolean fitSystemWindows​(Rect insets)
        Deprecated.

        Return the most recent frame as a bitmap.
        Returns:
        A bitmap.

      • onFirstFrame

        public void onFirstFrame()
        Deprecated.

      • getSystemPointerIcon

        @RequiresApi(24)
@NonNull
public PointerIcon getSystemPointerIcon​(int type)
        Deprecated.
        Description copied from interface: io.flutter.plugin.mouse.MouseCursorPlugin.MouseCursorViewDelegate
        Gets a system pointer icon object for the given type.

        If typeis not recognized, returns the default pointer icon.

        This is typically implemented by calling PointerIcon.getSystemIcon(android.content.Context, int) with the context associated with this view.

        Specified by:
        getSystemPointerIcon in interface io.flutter.plugin.mouse.MouseCursorPlugin.MouseCursorViewDelegate

      • onTextInputKeyEvent

        public boolean onTextInputKeyEvent​(@NonNull

        onTextInputKeyEvent in interface KeyboardManager.ViewDelegate
        Parameters:
        keyEvent - the KeyEvent that should be processed by the text input system. It must not be null.
        Returns:
        Whether the text input handles the key event.

        Deprecated.
        Description copied from interface: BinaryMessenger
        Sends a binary message to the Flutter application.
        Specified by:

        Deprecated.
        Description copied from interface: BinaryMessenger
        Sends a binary message to the Flutter application, optionally expecting a reply.

        Any uncaught exception thrown by the reply callback will be caught and logged.

        Specified by:
        send in interface BinaryMessenger
        Parameters:
        channel - the name String of the logical channel used for the message.

        callback - a BinaryMessenger.BinaryReply callback invoked when the Flutter application responds to the message, possibly null.

      • setMessageHandler

        @UiThread
public void setMessageHandler​(@NonNull
                              String channel,
                              @NonNull
                              BinaryMessenger.BinaryMessageHandler handler)
        Deprecated.
        Description copied from interface: BinaryMessenger
        Registers a handler to be invoked when the Flutter application sends a message to its host platform.

        Registration overwrites any previous registration for the same channel name. Use a null handler to deregister.

        If no handler has been registered for a particular channel, any incoming message on that channel will be handled silently by sending a null reply.

        Specified by:
        setMessageHandler in interface BinaryMessenger
        Parameters:
        channel - the name String of the channel.
        handler - a BinaryMessenger.BinaryMessageHandler to be invoked on incoming messages, or null.

        Description copied from interface: BinaryMessenger
        Registers a handler to be invoked when the Flutter application sends a message to its host platform.

        Specified by:
        setMessageHandler in interface BinaryMessenger
        Parameters:
        channel - the name String of the channel.
        handler - a BinaryMessenger.BinaryMessageHandler to be invoked on incoming messages, or null.
        taskQueue - a BinaryMessenger.TaskQueue that specifies what thread will execute the handler. Specifying null means execute on the platform thread.
