Game launcher Flutter · Dart Alpha 0.0.1

Project Yume

A digital sanctuary, not a database.

Modern game launchers are sterile and utilitarian. PC gamers juggle five or more separate apps — Steam, RetroArch, Dolphin, the Epic launcher, whatever Switch emulator is current — each one looking like a spreadsheet pretending to be a game shelf. The library is fragmented. The experience is fragmented.

Project Yume was built as a rejection of that coldness. One window, every system, designed to feel like a place worth spending time in even when you're not playing anything.

Liquid Glass UI

10 fully swappable themes — Daydream, Neo Tokyo, Café Leblanc, Deep Sleep, Spirit Woods and more — re-rendering gradients, borders, and glass opacity in real time without a restart.

Director Engine

A single launch system for PC games and emulated ROMs. Dart's Process.start on Windows, native open -n -a on macOS. A regex normalizer maps messy folder names to canonical platform IDs.

Three view modes

Grid with a live density slider, List as an animated folder structure sorted by platform, and Carousel — an overlapping PageView shelf built for controller navigation.

Offline by contract

Zero cloud calls. The entire library, notes, and buddy list persists as local JSON via shared_preferences. No accounts, no telemetry, no loading spinner waiting on a backend.

Yume Network

A personal dashboard with recent notes, recently played, and Comfy Buddies — all local. A built-in web engine (WebKit on macOS, Edge on Windows) means you never have to alt-tab away.

Tactile audio engine

SystemSound.play and HapticFeedback.selectionClick() turn every hover and tap into a physical-feeling moment. The UI doesn't just look alive — it feels it.
