In my search for how Dart AOT works, I have not found many resources except this video. I would like to know how it is that code can be compiled down to native machine code, such as Android or iOS, when there exists different pieces of hardware that code needs to run on.
From what I understand, there are only descriptions of apps produced in Flutter. That description (written in Dart) is then compiled down to native machine code, but how? A program written in Swift is different from a program written in Kotlin.

Using the Dart language allows Flutter to compile the source code ahead-of-time to native code. The engine's C/C++code is compiled with Android's NDK or iOS' LLVM. Both pieces are wrapped in a “runner” Android and iOS project, resulting in an apk or ipa file respectively.
The Angular ahead-of-time (AOT) compiler converts your Angular HTML and TypeScript code into efficient JavaScript code during the build phase before the browser downloads and runs that code. Compiling your application during the build process provides a faster rendering in the browser.
What is JIT and AOT in flutter? Dart's compiler technology lets you run code in different ways: Native platform: For apps targeting mobile and desktop devices, Dart includes both a Dart VM with just-in-time (JIT) compilation and an ahead-of-time (AOT) compiler for producing machine code.
Release-mode Flutter-based Android apps will generate AOT snapshots instead of shipping with bytecode or Dart code, like Debug-mode apps may choose to. The AOT snapshot contains a state of the Dart VM required to run the pre-compiled code. The plugin supports AOT snapshots compiled with Dart version 2.10 to 2.17.
A compiler creates the binary code from Dart source code. For mobile applications the source code is compiled for multiple processors ARM, ARM64, x64 and for both platforms - Android and iOS. This means there are multiple resulting binary files for each supported processor and platform combination.

Not sure what you mean by that. The concept of source code and compilation to a target platform is basically the same for each programming language. JIT (Just in Time) compiles at runtime on-the-fly while AOT (Ahead of Time) compiles before the application is deployed and launched.
A program written in Swift is different from a program written in Kotlin.
Also not sure what you mean by that. Swift can compile to native code and Java to Java bytecode. Swift is AoT while Java is JiT. The end result is always binary code for the target platform and CPU.
