@protocol FlutterTextureRegistry <NSObject>

Swift

protocol FlutterTextureRegistry : NSObjectProtocol

A collection of registered FlutterTexture‘s.

  • Registers a FlutterTexture for usage in Flutter and returns an id that can be used to reference that texture when calling into Flutter with channels. Textures must be registered on the platform thread. On success returns the pointer to the registered texture, else returns 0.

    Declaration

    Objective-C

    - (int64_t)registerTexture:(nonnull NSObject<FlutterTexture> *)texture;

    Swift

    func register(_ texture: FlutterTexture) -> Int64

  • Notifies Flutter that the content of the previously registered texture has been updated.

    This will trigger a call to -[FlutterTexture copyPixelBuffer] on the raster thread.

    Declaration

    Objective-C

    - (void)textureFrameAvailable:(int64_t)textureId;

    Swift

    func textureFrameAvailable(_ textureId: Int64)

  • Unregisters a FlutterTexture that has previously regeistered with registerTexture:. Textures must be unregistered on the platform thread.

    Declaration

    Objective-C

    - (void)unregisterTexture:(int64_t)textureId;

    Swift

    func unregisterTexture(_ textureId: Int64)

    Parameters

    textureId
