Sossoldi

Sossoldi is a free, MIT-licensed wealth management app built with Flutter by the RIP-Comm community. It exists to replace a blogger's Google Sheets net worth tracker with a friendly mobile and desktop client, so non-technical users can track net worth, expenses, and investments without touching a spreadsheet. The codebase is a single Dart project that ships to iOS, Android, macOS, Windows, Linux, and the Web.

Why it matters

• Truly cross-platform from one tree. The repo contains android/, ios/, macos/, windows/, linux/, and web/ folders alongside a shared lib/. The same screens, charts, and database code run on a phone, a desktop, or a browser tab.
• Local-first by design. All financial data is stored on the device using sqflite (with sqflite_common_ffi for desktop and sqlite3_flutter_libs for the native bindings). There is no required backend, so privacy-sensitive totals never leave the device unless the user explicitly shares them.
• Modern Flutter stack. State is managed with flutter_riverpod (3.x) plus riverpod_annotation and riverpod_generator, models are built with freezed and json_serializable, and fl_chart powers the charts. Code generation runs through build_runner, and the project is pinned to Flutter 3.10.7 via an .fvmrc file.
• Polished UX foundation. Assets include a custom NunitoSans font family (regular + italic weights from 200 to 900), native splash screens, generated launcher icons, and fl_chart visual reports — all batteries-included in the repo.

How it works

The lib/ directory follows a conventional layered layout: constants/, model/ (domain entities), providers/ (Riverpod state), services/ (persistence and platform plumbing), pages/ (screen-level UI), routes/, and ui/ (reusable widgets). The entry point is lib/main.dart, which wires the Riverpod providers into the route tree.

Persistence is built around SQLite. sqflite provides the database on mobile, while sqflite_common_ffi activates the desktop bindings on macOS, Windows, and Linux. path_provider resolves the database file location, shared_preferences stores small settings, and flutter_local_notifications plus timezone power recurring transaction reminders. local_auth gates access behind biometrics on devices that support it.

The Phase 1 feature set covers a Dashboard, a Movements page, basic Onboarding, and basic Settings, with bank account balances entered manually (PSD2 Open Banking API integration is on the roadmap). Visualization uses fl_chart; imports and exports flow through the csv and file_picker packages; device_info_plus, package_info_plus, url_launcher, and permission_handler fill in the platform-introspection glue. The test suite runs on test with flutter_lints enforcing style, and dependency_validator keeps the dependency tree honest.

Caveats

• Early-stage roadmap. The Phase 1 list (expenses, income, basic statistics, local-only storage) is still in progress; investment tracking, multi-currency, tax, and PSD2 integration are planned but not yet shipped.
• Spreadsheet-first origins. The data model is designed around a single user's net worth tracker, so multi-user or household scenarios are not yet supported.
• Cross-platform data sharing is manual. Cross-platform sharing is listed as a feature, but in the current build users move data between devices via import/export rather than sync, so there is no automatic cloud reconciliation.

Deployment notes

git clone https://github.com/RIP-Comm/sossoldi.git
cd sossoldi
fvm install              # honors .fvmrc (Flutter 3.10.7)
flutter pub get
dart run build_runner build --delete-conflicting-outputs
flutter run              # or: flutter run -d chrome

Distribution: official builds are published on the App Store, Google Play, and F-Droid. Project documentation lives at https://rip-comm.github.io/sossoldi/; community chat is on Discord (discord.sossoldi.com).

Integration tip: if you curate an Astro/Grove directory like this one, Sossoldi is the canonical "local-first Flutter finance" example for any app tagged personal-finance or wealth-management — its single-codebase-to-six-platforms story also makes a strong reference for cross-platform Flutter showcases.
