DartFlutter如何编译为Android？

概述我找不到任何具体资源,Dart是否已编译为JVM,还是Google的团队将DartVM编译为在JVM上运行,然后在JVM内的DartVM中运行Dart？前者更有意义,并且与“nobridge”的口头禅相呼应,但后者似乎更符合howintegrationbetweennative&fluttercodelookslike的要求.解决方法:Dart被编

我找不到任何具体资源,Dart是否已编译为JVM,还是Google的团队将Dart VM编译为在JVM上运行,然后在JVM内的Dart VM中运行Dart？

前者更有意义,并且与“ no brIDge”的口头禅相呼应,但后者似乎更符合how integration between native & flutter code looks like的要求.

解决方法:

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)捆绑在一起,以与本机平台进行交互.

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.
