How does Flutter ensure compatibility and optimization for iOS platform?

Flutter provides compatibility with iOS by using its own rendering engine, which operates on top of platform APIs. Dart code is compiled into native ARM code for iOS, ensuring high performance. To optimize, Flutter uses Ahead-of-Time (AOT) compilation, minimizes the use of bridges between Dart and native code, and employs its own rendering, which allows it to bypass UIKit limitations and provide a consistent UI across all platforms.
