Class FlutterSurfaceView

android.view.View

android.view.SurfaceView

io.flutter.embedding.android.FlutterSurfaceView

All Implemented Interfaces:

Drawable.Callback, AccessibilityEventSource, KeyEvent.Callback, RenderSurface

public class FlutterSurfaceView
extends SurfaceView
implements RenderSurface

Paints a Flutter UI on a Surface.

To begin rendering a Flutter UI, the owner of this FlutterSurfaceView must invoke attachToRenderer(FlutterRenderer) with the desired FlutterRenderer.

To stop rendering a Flutter UI, the owner of this FlutterSurfaceView must invoke detachFromRenderer().

A FlutterSurfaceView is intended for situations where a developer needs to render a Flutter UI, but does not require any keyboard input, gesture input, accessibility integrations or any other interactivity beyond rendering. If standard interactivity is desired, consider using a FlutterView which provides all of these behaviors and utilizes a FlutterSurfaceView internally.

getAttachedRenderer

@Nullable
public FlutterRenderer getAttachedRenderer()

Description copied from interface: RenderSurface

Returns the FlutterRenderer that is attached to this RenderSurface, or null if no FlutterRenderer is currently attached.

Specified by:

getAttachedRenderer in interface RenderSurface

attachToRenderer

public void attachToRenderer(@NonNull
 FlutterRenderer flutterRenderer)

Invoked by the owner of this FlutterSurfaceView when it wants to begin rendering a Flutter UI to this FlutterSurfaceView.

If an Android Surface is available, this method will give that Surface to the given FlutterRenderer to begin rendering Flutter's UI to this FlutterSurfaceView.

If no Android Surface is available yet, this FlutterSurfaceView will wait until a Surface becomes available and then give that Surface to the given FlutterRenderer to begin rendering Flutter's UI to this FlutterSurfaceView.

Specified by:

attachToRenderer in interface RenderSurface

detachFromRenderer

public void detachFromRenderer()

Invoked by the owner of this FlutterSurfaceView when it no longer wants to render a Flutter UI to this FlutterSurfaceView.

This method will cease any on-going rendering from Flutter to this FlutterSurfaceView.

Specified by:

detachFromRenderer in interface RenderSurface

pause

public void pause()

Invoked by the owner of this FlutterSurfaceView when it should pause rendering Flutter UI to this FlutterSurfaceView.

Specified by:

pause in interface RenderSurface

resume

public void resume()

Description copied from interface: RenderSurface

Instructs this RenderSurface to resume forwarding Surface notifications to the FlutterRenderer that was previously connected with RenderSurface.attachToRenderer(FlutterRenderer).

Specified by:
