Build & release

Producing installable artifacts for the Schuly app. All commands are package.json scripts run via bun - see Development setup for prerequisites and a flavor overview.

Release APKs

bun run build:apk:dev    # flutter build apk --flavor dev  --release
bun run build:apk:prod   # flutter build apk --flavor prod --release

Flavor	Application ID	Display name
dev	com.schuly.app.dev (version name suffix -DEV)	Schuly DEV
prod	com.schuly.app	Schuly

The two flavors install side by side, so a dev build never overwrites a prod build on the same device.

Pointing a dev build at a custom backend

BACKEND_BASE_URL=https://example.test bun run build:apk:dev:url

build:apk:dev:url forwards $BACKEND_BASE_URL through --dart-define=BACKEND_BASE_URL.

iOS build

bun run build:ios   # flutter build ios --flavor prod --no-codesign

Builds the prod flavor without code signing (sign separately in Xcode / your signing pipeline).

Install over adb

Build and install the release APK onto the currently connected adb target:

bun run install:dev    # build dev  APK, then flutter install --flavor dev
bun run install:prod   # build prod APK, then flutter install --flavor prod

When running against a locally hosted backend over USB, reverse the backend port first so the device can reach localhost:5033:

bun run adb:reverse        # adb reverse tcp:5033 tcp:5033
bun run install:dev:usb    # adb:reverse + install:dev

To install a dev build pointed at a custom backend URL:

BACKEND_BASE_URL=https://example.test bun run install:dev:url

App icons

The launcher icon is generated from assets/app_icon.png via flutter_launcher_icons (Android + iOS, configured in pubspec.yaml). After changing the source image:

bun run icons   # dart run flutter_launcher_icons
