What are the purposes of compilation types in Dart?

Compilation types in Dart (JIT and AOT) are used to optimize the development process and the performance of release applications.

• JIT (Just-In-Time) compilation is used during development.

  • Provides quick code reloads when making changes (hot reload, hot restart).
  • Allows code to be executed while writing, which is convenient for debugging.
  • Less efficient in performance compared to AOT.

• AOT (Ahead-Of-Time) compilation is used for building release versions of applications.

  • Compiles Dart code into native machine code before the application runs.
  • Ensures maximum performance and fast application startup.
  • Takes more time to compile compared to JIT.
  • The resulting binary file is usually larger in size.

The choice between JIT and AOT depends on the stage of the application lifecycle: JIT for development, AOT for production.
