    Fluro

    Fluro

    Fluro is a Flutter routing library that adds flexible routing options

    Fluro is a lightweight, flexible routing library for Flutter that brings expressive, URL-like navigation to mobile apps. It lets developers define route patterns with path parameters and optional query strings, making it simple to extract dynamic values from navigation paths. The library focuses on clear, centralized route configuration, reducing boilerplate compared to hand-rolled navigation code. It supports custom route transitions so screens can animate in ways that match an app’s brand and motion language. Error handling hooks help capture unknown routes, and developers can funnel users to fallback pages or gracefully redirect. Because it sits close to Flutter’s own navigation mechanisms, it integrates cleanly and remains easy to adopt incrementally. Fluro’s sweet spot is teams that want readable, testable route tables and predictable parameter passing without heavy architectural overhead.

    Flutter Example Apps

    Flutter Example Apps

    Basic Flutter apps, for flutter devs

    FlutterExampleApps is a curated repository of Flutter application source code and demos intended to help developers learn Flutter development through real-world examples and practical implementations of common app patterns. Instead of being a single app, it consists of dozens of example projects including clones of popular apps, utility apps, interactive UIs, and Flutter integrations with plugins and device features, covering topics from basic widgets to Firebase integration and responsive layouts. This repository is frequently starred and forked by developers because it provides a broad, hands-on showcase of how different features of the Flutter framework and Dart language are used in practice. Each example typically links to online resources or videos that walk through how the app was built, making it both a reference collection and a learning tool for beginners and intermediates alike.

    Flutter Plugins

    Flutter Plugins

    Plugins for Flutter maintained by the Flutter team

    This repository (now archived) houses the first-party plugin implementations maintained by the Flutter team, enabling access to platform-specific APIs (e.g. camera, file access, web views, etc.) from Dart/Flutter code. It essentially provides the bridge between Flutter apps and native mobile capabilities: for each plugin, there is often a Dart interface and underlying platform code (Android, iOS, etc.). Over time, the content of this repo has been moved to a newer monorepo or reorganized under flutter/packages. The plugins here are intended to follow Flutter’s design conventions and support integration with the wider Flutter ecosystem (published on pub.dev). Because the repository is archived, it is now read-only; future development of plugin code occurs elsewhere in the official Flutter organization.

    Flutter Widgets

    Flutter Widgets

    Source code for various Flutter widgets that are developed by Google

    flutter.widgets (often referred to as the “Flutter Widgets” extras) is a grab bag of production-hardened widgets, utilities, and patterns that complement Flutter’s core framework. It showcases best practices for adaptive layouts, scrolling behavior, input handling, and platform nuances that occur in real apps—not just demos. Many components are small, focused building blocks you can compose, which keeps your widget tree readable while solving thorny UI edge cases. The package is also a reference for testing strategies and state interactions that the core framework leaves to app authors. Because these widgets are maintained alongside Google’s Flutter efforts, they track framework changes and help apps upgrade smoothly. Teams use the collection to accelerate delivery and to standardize UI behavior across codebases.

    FunctionalPlus

    FunctionalPlus

    Functional Programming Library for C++

    Great code should mostly be self-documenting, but while using C++ in reality you can find yourself dealing with low-level stuff like iterators or hand-written loops that distract from the actual essence of your code. FunctionalPlus is a small header-only library supporting you in reducing code noise and in dealing with only one single level of abstraction at a time. By increasing brevity and maintainability of your code it can improve productivity (and fun!) in the long run. It pursues these goals by providing pure and easy-to-use functions that free you from implementing commonly used flows of control over and over again.

    Git Time Machine

    Git Time Machine

    Atom package that allows you to travel back in commit history

    git-time-machine is a user interface (often as an editor plugin or UI extension) that allows users to browse a file’s history visually, stepping back and forth through revisions in Git like a “time machine.” It shows changes to a file over time, lets users compare older states, and often provides diff and blame views to understand how the file evolved. Instead of just opening a commit log or diff, git-time-machine gives an interactive, incremental experience where you can slide through versions and see content changes in place. This is especially helpful when diagnosing when bugs were introduced, exploring regression contexts, or reviewing code evolution visually. For projects with many commits, it accelerates historical exploration, and it is commonly integrated into editors so developers can use it in their working environment.

    GitHub Cheat Sheet

    GitHub Cheat Sheet

    A list of cool features of Git and GitHub

    GitHub Cheat Sheet is a curated list of tips, tricks, and “hidden” features of Git and GitHub assembled into a single, readable cheat sheet. It collects commands, workflows, and UI shortcuts that many developers are not aware of, such as advanced uses of git log, git reflog, GitHub keyboard shortcuts, URL hacks, and useful configuration settings. The project was inspired by Zach Holman’s talks on Git and GitHub secrets and aims to turn those scattered insights into a living document. The cheat sheet is organized into sections like “GitHub Search,” “GitHub Secrets,” “GitHub Security,” “Git Tips,” and so on, so readers can focus on specific aspects of the Git/GitHub workflow. It is maintained as a Markdown README, which means it can be read directly on GitHub, printed, or incorporated into internal docs. With tens of thousands of stars, it has become a popular resource for both newcomers and experienced developers who want to level up their GitHub usage.

    GoNB

    GoNB

    GoNB, a Go Notebook Kernel for Jupyter

    Go is a compiled language, but with very fast compilation, that allows one to use it in a REPL (Read-Eval-Print-Loop) fashion, by inserting a "Compile" step in the middle of the loop -- so it's a Read-Compile-Run-Print-Loop — while still feeling very interactive. GoNB leverages that compilation speed to implement a full-featured (at least it's getting there) Jupyter notebook kernel. As a side benefit it works with packages that use CGO — although it won't parse C code in the cells, so it can't be used as a C kernel. It already includes many goodies: cache between cell of results, contextual help and auto-complete (with gopls), compilation error context (by mousing over), bash command execution, images, html, etc. See the tutorial. It's been heavily used by the author (in developing GoMLX, a machine learning framework for Go), but should still be seen as experimental — if we hear success stories from others, we can change this.

    Golden Layout

    Golden Layout

    A multi window layout manager for webapps

    Golden Layout is a JavaScript layout manager designed for building complex, multi-panel web applications with draggable and resizable components. It enables developers to arrange UI elements into flexible layouts that can be dynamically reconfigured by users through drag-and-drop interactions. The system is particularly useful for dashboards, IDE-like interfaces, and data-heavy applications where multiple panels need to coexist and be rearranged. Golden Layout manages component positioning, visibility, and resizing through a structured layout tree, allowing precise control over how elements are displayed. It also supports saving and restoring layouts, enabling persistence of user configurations across sessions. The library integrates with popular frontend frameworks such as Angular and Vue, and includes support for virtual components to bridge framework-specific rendering models.

    Google API JavaScript Client

    Google API JavaScript Client

    Google APIs Client Library for browser JavaScript, aka gapi

    This library (often used via gapi) provides a browser-friendly way to call Google APIs using OAuth 2.0 and generated discovery documents. It abstracts discovery, auth, and HTTP details so developers can focus on domain calls like Drive file operations, Calendar events, or YouTube data. The client can load APIs dynamically at runtime, which keeps bundles small and allows late-binding to specific services and versions. It includes helpers for incremental auth, token refresh, and scopes so apps can request only what they need when they need it. Responses are returned as promise-based calls with typed parameters derived from service definitions, simplifying error handling and pagination. Because it runs in the browser, it’s a natural fit for single-page apps that integrate deeply with Google services.

    Google CTF

    Google CTF is the public repository that houses most of the challenges from Google’s Capture-the-Flag competitions since 2017 and the infrastructure used to run them. It’s a learning and practice archive: competitors and educators can replay tasks across categories like pwn, reversing, crypto, web, sandboxing, and forensics. The code and binaries intentionally contain vulnerabilities—by design—so users can explore exploit chains and patching in realistic settings. The repo also includes infrastructure components and links to a scoreboard implementation, giving organizers reference material for hosting their own events. As a living archive, it documents changes in exploitation trends and defensive techniques year over year. Clear warnings advise against deploying challenge infrastructure in production due to purposeful insecurities.

    Google Cloud Dataflow Template Pipelines

    Google Cloud Dataflow Template Pipelines

    Cloud Dataflow Google-provided templates for solving data tasks

    DataflowTemplates is the source repository for Google-provided Dataflow templates that are intended to solve large-scale in-cloud data processing tasks without requiring users to build everything from scratch in a full development environment. The repository is centered on templated pipelines powered by Google Cloud Dataflow and Apache Beam, making it easier to run common integration and movement jobs such as data import, export, backup, restore, and bulk API operations. Its structure shows support for multiple generations of templates, including v1 and v2 implementations, as well as related metadata, YAML assets, plugins, and Python components that support broader template execution and maintenance. This design makes the project more than a sample set, because it acts as the implementation base for official Google-provided templates used in real cloud data workflows.
