Dart被编译为本机代码(ARM，Intel等)可执行文件，并与某些本机平台代码(Java，Kotlin，Objective-C/Swift)与本机平台进行交互.

Dart is compiled to native machine code (ARM, Intel, ...) executable and bundled with some native platform code (Java, Kotlin, Objective-C/Swift) to interact with the native platform.

Flutter如何在Android上运行我的代码?引擎的C和C ++代码

是使用Android的NDK编译的.Dart代码(SDK和您的)被提前(AOT)编译到本地的ARM库中.该库包含在运行程序" Android项目中，整个库东西内置在APK中.启动后，该应用会加载Flutter图书馆.任何呈现，输入或事件处理等都是委托给已编译的Flutter和应用程序代码.这类似于许多游戏引擎的工作方式.

How does Flutter run my code on Android? The engine’s C and C++ code

are compiled with Android’s NDK. The Dart code (both the SDK’s and yours) are ahead-of-time (AOT) compiled into a native, ARM library. That library is included in a "runner" Android project, and the whole thing is built into an APK. When launched, the app loads the Flutter library. Any rendering, input or event handling, and so on, are delegated to the compiled Flutter and app code. This is similar to the way many game engines work.

Debug mode builds use a virtual machine (VM) to run Dart code (hence the "debug" banner they show to remind people that they’re slightly slower) in order to enable stateful hot reload.
