Questions and Answers

What is the purpose of Ahead-of-Time (AOT) compilation in Flutter's production mode?

To compile Dart code into Java for compatibility.

To generate optimized native binaries for the device's CPU architecture. (correct)

To translate the application into multiple programming languages.

To interpret Dart code on runtime for flexibility.

Which rendering technology does Flutter primarily use to optimize graphical performance?

Direct2D to improve application responsiveness.

OpenGL for cross-platform graphics rendering.

Skia for pixel-level rendering and enhanced performance. (correct)

Canvas API for web-based graphics rendering.

How does the Embedders layer facilitate user interaction in Flutter applications?

By converting input events into a format understandable by Flutter's engine. (correct)

By directly accessing native libraries for improved performance.

By managing the graphical user interface irrespective of user inputs.

By implementing native event listeners for each platform.
