Flet 1.0 framework released for creating cross-platform applications on Python

The team of developers presented Flet 1.0 — a stable version of the framework that allows creating full-fledged graphical interfaces in the Python language. The tool is focused on developing cross-platform applications that work in a browser, on desktop and mobile devices without the need to learn JavaScript or HTML.

The release includes over 150 ready-made controls that allow designing complex user interfaces. The framework supports integration with any native Python libraries, which gives the opportunity to use existing packages for data processing, network interaction or interaction with AI models directly within the application.

To accelerate the development process, the browser studio is included in Flet 1.0. It provides a visual editor that allows you to see changes in the code and layout in real-time. The toolkit supports hot reload, which reduces the time spent on debugging the interface and checking the logic of component operation.

The architecture of the solution is based on the principles of declarative programming, which simplifies project scaling. Developers can deploy ready-made applications as static websites or package them into executable files for Windows, macOS, and Linux. Support for mobile platforms is implemented through native containers that provide access to the device's system API.

The release of version 1.0 marks the transition of the project to the stage of long-term support. This solution reduces the entry barrier for Python developers who want to create full-fledged products with a graphical interface without having to learn the web technology stack or specialized frameworks for each individual platform.
