Can you explain what AOT compilation is and how it works?

AOT compilation (Ahead-Of-Time) is the process of compiling source code into machine code in advance, before the application is run.

Unlike JIT (Just-In-Time), where compilation occurs during execution, AOT allows for creating an executable file that is ready to run immediately without additional compilation.

In Flutter, AOT compilation is used for building release versions of applications, which provides:

• Fast application startup
• Optimized performance
• Reduced resource consumption

Example: when building a Flutter application for Android or iOS, the source Dart code is compiled into native ARM code in advance, which speeds up operation on the device.
