Introduction

👋 Hey there

I'm Simon (Phạm Quốc Cường). I've been crafting apps with Flutter & Dart since late 2018.

I love building beautiful and impactful things.

Right now, all of that energy goes into one thing: Lumide.

What's Lumide?

A desktop code editor. Pure Dart. Pure Flutter. Zero Electron.

Every piece — the text engine, the pane system, the plugin SDK — is built from scratch. No wrappers. No shortcuts. Just clean, native code running on Skia/Impeller.

The rule of thumb is simple: if it can be done in pure Dart, it should be.

What that gets you:

• ⚡ ~300ms cold start, ~60MB RAM baseline
• 🧠 Full LSP support — completions, diagnostics, go-to-definition
• 🔌 Plugin SDK for community extensions
• 🖥 Integrated terminal with multi-tab PTY
• 🎨 Customizable everything — themes, keymaps (VS Code / JetBrains / Sublime), layouts
• 🍎 macOS today. Windows & Linux next.

Open source packages under 🦊 SoFluffyOS:

• panes — Resizable multi-pane layouts for Flutter (the kind you need for IDE-like UIs)
• lumide_api — The official Lumide plugin SDK
• easy_hive — A simpler Hive wrapper
• gms_check — Google Services checker for Android

Why sponsor?

Building an IDE solo is... a lot. But I believe developers deserve a native, fast, and beautiful editor that isn't wrapped in a browser engine.

Your sponsorship helps me:

• Dedicate more time to building Lumide
• Cover the boring stuff — CI, code signing, distribution, hosting
• Keep the SDK and packages open-source and accessible
• Ship to more platforms, faster
