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. -

Douya Bean sprouts
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. -

React Native Navigation
A complete native navigation solution for React Native
React Native Navigation is a module, dependent on and intended to be used alongside React Native, so some experience with it and knowledge of core concepts is required. We also assume you are working on a Mac with XCode and Android Studio installed and setup. You can also make it work in a Linux distribution, of course, but in that case bear in mind that some sections of the docs that deal with iOS might not be relevant to you. When your app is launched for the first time, the bundle is parsed and executed. At this point you need to display your UI. To do so, listen to the appLaunched event and call Navigation.setRoot when that event is received. When your app is launched, RN makes sure JS context (which is what enables you to execute JavaScript code) is running. There are quite a few differences between iOS and Android in this regard. -

React Native Tab View
A cross-platform Tab View component for React Native
A cross-platform Tab View component for React Native. Implemented using react-native-pager-view on Android & iOS, and PanResponder on Web, macOS, and Windows. To use this library you need to ensure you are using the correct version of React Native. If you are using a version of React Native that is lower than 0.63 you will need to upgrade that before attempting to use this library. The package exports a TabView component which is the one you'd use to render the tab view, and a TabBar component which is the default tab bar implementation. Always define your components elsewhere in the top level of the file. If you pass inline functions, it'll re-create the component every render, which will cause the entire route to unmount and remount every change. It's very bad for performance and will also cause any local state to be lost. -
