________ in Flutter is a technique used to compile and optimize the app for the specific architecture of the target device.

Ahead-of-Time (AOT) Compilation in Flutter is a technique where the Dart code is compiled to machine code ahead of runtime. This results in a more optimized and efficient execution on the target device. AOT compilation is particularly beneficial for release builds, as it reduces startup time, improves app performance, and ensures compatibility with devices that do not allow runtime code generation (JIT).
