## ◆ dispatchPointerDataPacket: [2/2]

- (void) dispatchPointerDataPacket: |  | (std::unique_ptr< flutter::PointerDataPacket >) | packet |

## ◆ iosPlatformView

- (PlatformViewIOS* FlutterEngine()): |  |  |

## ◆ launchEngine:libraryURI:entrypointArgs:

- (void) launchEngine: |  | (nullable NSString *) | entrypoint
libraryURI: |  | (nullable NSString *) | libraryOrNil
entrypointArgs: |  | (nullable NSArray< NSString * > *) | entrypointArgs

## ◆ notifyLowMemory

- (void) notifyLowMemory |  |  |

## ◆ platformPlugin

- (FlutterPlatformPlugin*) platformPlugin |  |  |

## ◆ platformTaskRunner

- (RefPtr<)fml: |  |  |

## ◆ platformView

- (WeakPtr<)flutter: |  |  |

## ◆ platformViewsController

- (shared_ptr<)flutter: |  |  |

## ◆ rasterTaskRunner

- (RefPtr<)fml: |  |  |

## ◆ restorationPlugin

- (FlutterRestorationPlugin*) restorationPlugin |  |  |

## ◆ screenshot:base64Encode:

- Rasterizer: |  | (flutter::Rasterizer::ScreenshotType) | type
base64Encode: |  | (bool) | base64Encode

## ◆ sendKeyEvent:callback:userData: [1/2]

- (void) sendKeyEvent: |  | (const FlutterKeyEvent &) | event
callback: |  | (nullable FlutterKeyEventCallback) | callback
userData: |  | (nullable void *) | userData

Dispatches the given key event data to the framework through the engine. The callback is called once the response from the framework is received.

## ◆ sendKeyEvent:callback:userData: [2/2]

- (void) sendKeyEvent: |  | (const FlutterKeyEvent &) | event
callback: |  | (nullable FlutterKeyEventCallback) | callback
userData: |  | (nullable void *) | userData

- (FlutterEngine*) spawnWithEntrypoint: |  | (nullable NSString *) | entrypoint
libraryURI: |  | (nullable NSString *) | libraryURI
initialRoute: |  | (nullable NSString *) | initialRoute
entrypointArgs: |  | (nullable NSArray< NSString * > *) | entrypointArgs

Creates one running FlutterEngine from another, sharing components between them.

This results in a faster creation time and a smaller memory footprint engine. This should only be called on a FlutterEngine that is running.

## ◆ textInputPlugin [1/3]

- (nonnull FlutterTextInputPlugin*) textInputPlugin |  |  |

## ◆ textInputPlugin [2/3]

- (FlutterTextInputPlugin*) textInputPlugin |  |  |

## ◆ uiTaskRunner [1/2]

- (RefPtr<)fml: |  |  |

## ◆ uiTaskRunner [2/2]

- (RefPtr<)fml: |  |  |

## ◆ updateViewportMetrics: [1/2]

- (void) updateViewportMetrics: |  | (flutter::ViewportMetrics) | viewportMetrics |

## ◆ updateViewportMetrics: [2/2]

- (void) updateViewportMetrics: |  | (flutter::ViewportMetrics) | viewportMetrics |

## ◆ waitForFirstFrame:callback:

- (void) waitForFirstFrame: |  | (NSTimeInterval) | timeout
callback: |  | (void(^)(BOOL didTimeout)) | callback
