Maintaining the Prism family β a cohesive suite of well-tested, pure-Flutter packages (all six platforms, no platform channels) for content rendering, adaptive UI, color theming, and app plumbing:
Content rendering
| Package | What it does | Badges |
|---|---|---|
| prism_markdown | Fast, plugin-free Markdown widget with full CommonMark + GFM support β the maintained replacement for the discontinued flutter_markdown. Now with maxLines/overflow truncation and background-isolate parsing |
|
| prism_code_view | Syntax-highlighted code viewer β built-in Dart/JSON/YAML tokenizers, copy button, line numbers, word wrap | |
| prism_changelog | In-app "What's New" screens β parses Keep-a-Changelog markdown into version cards, tracks last-seen versions |
Color & theming
| Package | What it does | Badges |
|---|---|---|
| prism_palette | Fast color palette extraction from images β dominant colors and the six classic swatches (vibrant, muted, light/dark variants) built on material_color_utilities. The maintained replacement for the discontinued palette_generator |
AI
| Package | What it does | Badges |
|---|---|---|
| prism_ai | Lean, provider-agnostic streaming client for AI chat completions β OpenAI, Ollama, Groq, DeepSeek and every OpenAI-compatible endpoint, with typed streaming events. Pairs with prism_markdown for live AI-response rendering |
Adaptive UI
| Package | What it does | Badges |
|---|---|---|
| prism_adaptive_scaffold | Responsive scaffolds β bottom bar β navigation rail β extended rail from one widget; replacement for the discontinued flutter_adaptive_scaffold |
|
| prism_adaptive_dialog | Adaptive dialogs β bottom sheets on phones, centered dialogs on desktop, from one call | |

| prism_search | Adaptive search β inline field with dropdown suggestions on desktop, full-screen search page on phones | |
| prism_settings | Ready-made settings screens β tiles, toggles, sliders, dropdowns, sections with built-in search |
App plumbing
| Package | What it does | Badges |
|---|---|---|
| prism_state_views | Empty, loading, error, and success states from one widget β Dart 3 sealed view-state classes | |
| prism_form | Declarative forms β composable validators, sealed submit states, inline errors, headless controller | |
| prism_toast | Adaptive toasts β bottom-centered on mobile, stacked top-right cards on desktop, icon-led variants | |
| prism_banner | Dismissible in-app announcement banners β persistence, scheduling, severity levels | |
| prism_pagination | Infinite-scroll lists β automatic load-more, retryable errors, empty and end-of-list states |
Delivered mobile applications for national and international clients β from concept through App Store / Google Play publication.

More about the Swift core contributions
- vapor/vapor #3610 β proposed and implemented
URLQueryContainer.contains(at:), a presence check for query key paths, backed by a decode-presence marker with full test coverage. - apple/swift-log #530 β resolved a documented-vs-actual contradiction in
MultiplexLogHandlermetadata priority; updated two tests that had encoded the incorrect behavior. - apple/swift-argument-parser #991 β fixed
generate-docc-referencerendering bare--for short-only/single-dash arguments; new example + snapshot tests, all 574 existing tests byte-identical. - apple/swift-argument-parser #993 β duplicate subcommand names/aliases now fail configuration with a clear error instead of silently shadowing.
- vapor/console-kit #250 β new
Console.printTable(_:style:)helper with auto-sized columns, bold header row, and 5 tests. - vapor/websocket-kit #164 β new
connectoverloads (Future, proxy, async/await) exposing the 101 upgrade responseHTTPResponseHeadto client code.
Every change: issue-linked, fully tested locally against the complete suite, zero regressions.
Small, well-tested, issue-linked changes with CI-clean delivery β and responsiveness with maintainers. Currently active in: Kiwix (Android + Apple), NewPipeExtractor, WordPress Mobile, the Apple Swift ecosystem (swift-log, swift-argument-parser, Vapor + satellite packages), and React Native native modules (webview, async-storage) β while maintaining the 15-package Prism family on pub.dev β now including AI tooling.
