    Termux Desktop

    Termux Desktop

    Setup A Beautiful Desktop/GUI In Termux

    Termux Desktop is a collection of dotfiles and scripts for setting up a graphical Linux-style desktop environment inside Termux on Android. It helps users turn a phone or tablet into a more complete desktop-like workspace without needing root access. The setup uses VNC so the desktop can be opened through a VNC client after installation. It includes an Openbox-based environment with visual themes, menus, app launchers, terminal tools, file management, browser access, and system applets. The project is especially useful for experimenting with coding, Linux tools, classic applications, and lightweight desktop workflows on Android hardware. Since the repository is archived and marked as unmaintained, it is best treated as a legacy reference setup rather than an actively supported Termux desktop solution.

    Flutter Go

    Flutter Go

    Demos and documentation for over 140 Flutter UI components

    flutter-go is a community-driven Flutter application that serves as an interactive catalog of Flutter widgets, layouts, and patterns. It organizes the Flutter ecosystem into browsable categories—basic widgets, material components, Cupertino elements, layout primitives, and animation demos—so learners can see how pieces behave in a running app. Each entry typically includes a live example, code snippet, and brief notes on properties or usage, turning the app into a hands-on reference you can run on your phone. The project targets newcomers and teams evaluating Flutter by shortening the path from documentation to tangible UI behavior. Because it’s itself a Flutter app, it demonstrates real project structure, navigation, state handling, and theming in practice. The result is a practical companion for discovery and prototyping, helping developers move from curiosity to confident implementation more quickly.

    A Material Design app for douban.com

    The open source Material Design Douban client. Among all people who directly access Douban, the most common and consistent usage is around ratings, comments, discoveries, and discussions around movies, TV, books, records, and events (what we call "items"). We will use the ratings and comments that are synchronized with the website as a starting point and basis to reconstruct the discovery and discussion around personal interests on the mobile phone. Douban is never a single website, and the usage of Douban is naturally different. Douban is used to obtain information, but whether the acquisition of information is based on entries and algorithms, or based on neighbors and people, this issue has probably remained unresolved in the multiple revisions of Douban. Douban Broadcasting has been one of the few Android Design applications in China a few years ago. Actively express the characteristics of Douban, such as broadcasting, neighbors, Douyou, etc.
