About

I am selling Breadcrumbs Mobile, a substantial Flutter/Dart mobile app source-code asset for Android and iOS.Breadcrumbs is a private, local-first place-memory app. Users can save meaningful places, attach text/photo/voice notes, organize places into collections and routes, revisit nearby memories, run saved routes, share selected content, import shared content after review, create backups, restore from backups, and manage local storage - all without requiring an account or backend.This is best suited for a buyer who wants a strong starting point for a mobile app business, travel/location product, private map notebook, local-first architecture project, or agency client project.What is included- Full Flutter/Dart source code.- Android and iOS Flutter project folders.- Riverpod state/composition architecture.- GoRouter routing.- Drift/SQLite local persistence.- App-owned platform adapter boundaries.- English and Turkish localization.- Places, notes, photo notes, voice notes, maps, nearby, collections, routes, reminders, app lock, share/import, backup/restore, storage management, settings/help/about.- Extensive tests across domain, data, controllers, widgets, goldens, performance, and platform adapters.- Buyer handoff documentation.- Technical documentation.- 21 sale screenshots generated from the real Flutter UI with local demo data.Technical snapshot- Flutter/Dart.- Version in `pubspec.yaml`: `1.0.1+2`.- `633` Dart files under `lib/`.- `214` Dart test files under `test/`.- `848` total Dart files across app/tests/integration.- Approximately `292,730` Dart lines by `wc -l` across app/tests/integration target.- Dependencies include Riverpod, GoRouter, Drift, Flutter Map, image picker, record, just_audio, local_auth, share_plus, file_picker, geolocator/geocoding, secure storage, and Flutter local notifications.Product scopeBreadcrumbs is intentionally:- local-first;- private by default;- free product model;- no subscriptions or paywalls;- no mandatory backend;- no account requirement;- no public publishing/social feeds;- no QR publishing;- no video-note authoring;- English/Turkish localized.A buyer can keep that strategy or change it after acquisition.Current statusThis is a strong source-code and product-handoff asset. It is not being sold as a live revenue business. There are no users or revenue included.The repository includes buyer-prepared documentation and sales screenshots. Public release validation still belongs to the buyer. Before public release, the buyer should run Android release validation, iOS build/runtime validation, choose a production map tile provider, and validate target-device platform flows such as notifications, app lock, file picking, sharing, importing, and restore.Why I am sellingI brought the project to a strong final-stage starting point. Rather than continuing to make every future product decision myself, I prefer to transfer it to a buyer who can decide the final release, positioning, validation, and commercial direction.Ideal buyer- Flutter developer or mobile agency.- Founder who wants a local-first maps/memory product foundation.- Buyer interested in travel, personal notes, private map notebook, location memory, or route planning apps.- Team that wants a substantial Flutter codebase with documentation and tests.
