Erebrus Drop

Current version: 1.0.5+5

Erebrus Drop is a local-first file and text sharing app for nearby devices. A phone can create a temporary Drop Room on the current Wi-Fi network or hotspot, and other devices can join from the mobile app or a browser without an account or cloud upload.

Release

Current release version:

1.0.5+5

Android release versioning:

• The number after + is the Android versionCode.
• Google Play permanently reserves any uploaded versionCode, even if the draft/release is discarded.
• Always increase the + build number before uploading another AAB.

The Android package id is:

com.erebrus.drop

Android uses two deploy flavors:

Flavor	Output	Store
playstore	AAB	Google Play
dappstore	APK	Solana dApp Store

Both signing blocks live in one file:

android/key.properties

Template:

android/key.properties.example

Full signing and publish commands:

docs/solana-dapp-store-release.md

Build commands:

# Debug Android defaults to playstore (no --flavor needed)
flutter run

# Google Play
flutter build appbundle --flavor playstore --release

# Solana dApp Store
flutter build apk --flavor dappstore --release

Desktop (macOS / Windows / Linux)

Erebrus Drop ships on macOS, Windows, and Linux as well: system tray, responsive layout, mDNS room discovery, folder library, and hide-to-tray on close.

Generate brand assets (tray icons, Dock/taskbar launcher icons, macOS About icon, Linux window icon) before a desktop release build:

python3 scripts/generate-desktop-assets.py

This runs tray icon generation and dart run flutter_launcher_icons for macOS/Windows/Android/iOS launcher icons from assets/images/erebrus-glossy.png.

Dev:

flutter pub get
python3 scripts/generate-desktop-assets.py   # first time or after logo changes
flutter run -d macos                       # or windows / linux

Release bundles (writes versioned artifacts under dist/):

./scripts/build-desktop.sh macos
./scripts/build-desktop.sh windows
./scripts/build-desktop.sh linux
./scripts/build-desktop.sh all             # macOS host; skips unavailable targets

Full desktop setup, packaging, and CI notes: docs/BUILD.md.

Development

Install dependencies:

flutter pub get

Run the app:

flutter run

Verify:

flutter analyze
flutter test

CI/CD

GitHub Actions:

• CI — flutter analyze and flutter test on every PR and main push
• Release — manual workflow: tags v{semver} from pubspec.yaml, uploads Android sideload APKs plus macOS .zip, Windows .zip, and Linux .tar.gz desktop bundles

Release checklist:

1. Bump version: in pubspec.yaml (e.g. 1.0.6+6).
2. Run python3 scripts/generate-desktop-assets.py if brand images changed.
3. Commit and push to main.
4. GitHub → Actions → Release → Run workflow.
5. Download artifacts from GitHub → Releases when the run finishes.

See docs/BUILD.md.

Native QR Scanner

The app uses its own platform-channel QR scanner instead of a third-party Flutter scanner plugin. Android uses CameraX with ZXing QR decoding. iOS uses AVFoundation QR metadata scanning. The scanner returns the raw Drop Link or Drop Code to Flutter, where the existing join parser validates and opens the room.

Local Network Debugging

Browse for advertised Drop Rooms on macOS:

dns-sd -B _erebrusdrop._tcp local

Resolve a discovered room:

dns-sd -L "<device name>" _erebrusdrop._tcp local

Check the room API:

curl http://<room-ip>:8787/api/room

Privacy

Erebrus Drop is designed for local device-to-device transfer. NetSepio does not collect analytics, advertising identifiers, contact lists, location history, account profiles, transferred files, pasted text, folder contents, room passwords, or Drop Links.

Erebrus Platform, brand, and apps are products of NetSepio.
