My understanding is that Flutter is compiled AOT. Can it be compiled as JIT instead of AOT, will it work and what is the switch that would do that?
Thanks!

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 native, ARM, and x86 libraries.
In theory, a Just-in-Time (JIT) compiler has an advantage over Ahead-of-Time (AOT) if it has enough time and computational resources available. A JIT compiler can be faster because the machine code is being generated on the exact machine that it will also execute on.
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.
Dart Native (machine code JIT and AOT) Your AOT-compiled app launches with consistent, short startup time. The AOT-compiled code runs inside an efficient Dart runtime that enforces the sound Dart type system and manages memory using fast object allocation and a generational garbage collector.
In development mode, Flutter is compiled just-in-time. That is why we can do hot-reload/restart so fast. In release mode (when you go to publish your app), your code is compiled ahead-of-time, to native code. It is for better performace, minimum size and remove other stuff that are useful in dev mode.

As per resource, I got the following points :
1) The Dart code is ahead-of-time (AOT) compiled into a native, ARM library.
2) 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.
