Flutter is a cross-platform mobile app development framework that allows developers to write code once in Dart and deploy to both Android and iOS. It uses common UI views across platforms and supports features like hot reload for quick development, a simple multithreading model, and targets API level 16 and above on Android and iOS 8 and above. However, Flutter may not support all necessary UI elements, uses more device resources than native apps, and has some limitations in functionality, plugin support, images, locales, and platform dependencies. It is best suited for startups, apps without offline syncing needs, and beginners in mobile programming.
