Overview
Flet enables writing full Flutter applications in Python or integrating server-driven UI experiences into existing Flutter apps. It allows developers to build cross-platform UIs using Python, leveraging Flutter's rich widget library and rendering engine. The package supports real-time updates and interactive UIs through a server-client architecture, making it ideal for rapid prototyping and dynamic interfaces. Flet also provides seamless integration with Flutter, allowing Python-based logic to drive Flutter widgets on multiple platforms.
