Nocterm

Nocterm is a terminal user interface (TUI) framework designed for the Dart programming language, offering a development experience modeled after Flutter. It enables developers to build interactive terminal applications using familiar Flutter-like APIs such as StatefulComponent, setState(), Row, and Column. The framework emphasizes a declarative, component-based approach, making code easy to read, test, and maintain.

Notable features of Nocterm include support for over 45 components, six built-in themes such as Nord, Dracula, and Gruvbox, and instant hot reload for rapid development. The framework offers built-in support for animations, mouse input, markdown rendering, differential rendering, and testing. Its architecture is based on a virtual terminal, and it provides a range of layout components like Row, Column, ListView, and Expanded. Nocterm also supports real-time updates and reactive UI patterns through setState().

The tool is particularly suited for Dart and Flutter developers, as it leverages APIs and design patterns familiar to those communities, resulting in a low learning curve. It is intended for building a wide variety of terminal applications, including dashboards, system monitors, chat clients, productivity tools, developer utilities, smart home dashboards, and games such as roguelikes and text adventures. Several example applications, including vide, snake, minesweeper, and nocterm_3d, have been built with Nocterm.

Nocterm is delivered as a Dart package and can be added to projects using the Dart package manager. Users can try live demos of Nocterm apps compiled to JavaScript and running in the browser.
