Flutter is Google's open-source SDK, hosted at flutter/flutter on GitHub, for building user interfaces across mobile, web, and desktop from a single Dart codebase. The repo is licensed BSD-3-Clause, and its README documents stateful hot reload, a Skia/Impeller rendering pipeline, and Material/Cupertino widget sets as the core pieces developers work with.

Awesome Flutter (Solido/awesome-flutter) is a curated list of Flutter resources on GitHub: articles, blog posts, video tutorials, and UI packages sorted into topic sections instead of one long feed of links. It follows the standard awesome-list format, markdown headings with a one-line description and author credit per entry, and it leans toward UI widgets and components more than general Dart theory.

Free Programming Books (Chinese) is justjavac's GitHub index of free programming books, translated manuals, and course notes in Chinese, organized under headings like AI, Go, C/C++, and version control. It's a link list, not a curriculum - entries range from full book translations to single blog posts, some flagged `:worried:` for dead links, and contribution happens only through pull requests.

Material Design Icons is Google's GitHub home for the icon assets behind Material Design: the modern Material Symbols variable fonts and the older, frozen Material Icons set, both released under Apache 2.0 and usable via Google Fonts, self-hosted files, or community npm packages.
