Flair is all about simplifying application development. It allows the developer to write modules of code and then use flair to define how they interact. Flair then generates the extra code to finalise the application

Use FlexColorScheme to make beautiful Flutter Material Design themes. Apply optional surface blends, and use Material-3 style seeded color schemes. The returned themes are standard ThemeData objects, but very sophisticated ones. They are based on the same idea as Flutter's ThemeData.from(ColorScheme) and ThemeData(colorSchemeSeed) themes, but with many additional features. Choose from numerous pre-made designs or make your own. You can also use optional component sub theming, that are quick and easy to configure. When you theme a Flutter application correctly, all built-in widgets use the colors of the ColorScheme in your theme. At least in theory, and it is almost so if you defined your ThemeData by using the ThemeData.from factory, but it misses a few details. This applies in particular when you use Material-2 design in Flutter, which is the default. When you opt in on using Material-3, the color results and styles are much more consistent by default.

FlexibleTree is a data structure allowing arbitrary relationships and rules to be implemented easily. Primarily, FlexibleTree encourages more flexible data sorting in overlapping categories.

Android library provides an implementation of the Material Design Floating Action Button Speed Dial for both classic View and Compose.

FC Designer is a standalone flowchart designer written in Java.

FlowLayout is an Android UI library that implements a “flow” or “tag cloud” layout where items automatically wrap onto new lines as needed, making it ideal for chips, product tags, and selectable labels. Instead of manually placing views, you feed data through an adapter-style API, so tags can be created dynamically from a list and refreshed when the dataset changes. The library supports selection behavior out of the box, including single-select and multi-select modes, so it can behave like a group of checkable chips without you building the state machinery from scratch. It also provides click and selection listeners that let you react when a user taps a tag or when the selected set changes, which is useful for filters and preference UIs. To keep the UI consistent, it can preserve selection state across activity recreation such as rotation, reducing edge-case bugs in real apps.

Fluid is a collection of cross-platform QtQuick components for building fluid and dynamic applications, using the Material Design guidelines. Online documentation is available at docs.liri.io. We develop using the git flow method this means that the develop branch contains code that is being developed and might break from time to time. If you want to check out a stable version just install one of the releases or clone the master branch that has the latest released version.

flutter_vignettes is a set of polished experimental projects that showcase creative uses of Flutter’s capabilities. Each vignette is a self-contained demo focusing on visuals, animations, or interactions, often pushing the boundaries of what Flutter’s rendering engine can achieve. Examples include custom UI widgets, fluid animations, and interactive design concepts. The project is intended to inspire developers and demonstrate Flutter’s potential for building expressive, high-quality experiences. It’s not only a code resource but also a design showcase, blending engineering and artistry. By presenting small, focused experiments, flutter_vignettes encourages experimentation and learning while illustrating Flutter’s strengths in rapid UI prototyping.

Font Mfizz is a scalable icon font featuring symbols for programming languages, operating systems, software tools, and technology themes—designed for "geek" style UIs. Icons are customizable via CSS and are available via CDN or direct download.

It is a point a click game creator that is based off the TrueVision3D engine. The creator will allow the user to create a 3D or 2D game in a gui interface. The software will then generate code that can be edited, or compiled into a functional game.

Fresh Juice is Java User Interface Codification Engine. It provides easy designing, storing and plugging-in of graphic user interfaces and appropriate applications in xml-extension format.

Front-End-Design-Checklist bridges the gap between design and implementation by capturing the essential details that make handoffs smooth and outcomes consistent. It encourages designers and developers to align on typography scales, color tokens, spacing systems, and grid behavior before coding begins. The resource includes checks for responsive breakpoints, interaction states, accessibility considerations, and asset preparation, reducing rework later in the build. It promotes shared vocabulary and artifacts, helping teams avoid ambiguities around components, states, and edge cases. By using it early in the process, teams can prevent visual drift, inconsistent spacing, and incomplete specifications. The result is a repeatable, predictable path from mockup to production-quality UI.

Frontend Slides is a lightweight tool that enables users to create visually appealing, animation-rich web presentations without requiring knowledge of CSS or JavaScript by leveraging a guided, interactive workflow. It operates on a “show, don’t tell” philosophy, generating visual previews of styles so users can select their preferred design rather than describing it abstractly. The system produces fully self-contained HTML presentations with inline CSS and JavaScript, eliminating the need for external dependencies, build tools, or frameworks. It also supports converting existing PowerPoint files into web-based presentations while preserving content such as images, text, and structure. The tool includes curated design presets that avoid generic AI-generated aesthetics, ensuring presentations feel distinctive and intentional. Its architecture uses progressive disclosure, loading only necessary components at each step to keep the workflow efficient and intuitive.
