Harness Flutter for High-Fidelity Apps

For a typical B2B or consumer MVP (authentication, core data flows, push notifications, five to eight screens), a native iOS + Android build requires two parallel engineering tracks — roughly 1,200–1,800 billable hours total. The equivalent Flutter build runs 700–1,100 hours, a 35–50% reduction. ABM Tech's Singapore-based senior Flutter engineers bill at $65–$110/hour depending on specialization, making a Flutter MVP typically $50,000–$100,000 fully delivered, versus $90,000–$180,000 for a dual-native build at equivalent quality.

For most business applications — dashboards, forms, lists, charts, transactional UIs — Flutter's Impeller rendering engine matches native performance and sometimes exceeds it due to consistent 60fps compositing. Where Flutter requires care is complex custom animations at 120fps on ProMotion displays and very large list virtualization (10,000+ items). ABM Tech engineers know where these limits sit and have optimized apps handling real-time financial data feeds, map overlays, and video playback without frame drops.

We default to Riverpod for new greenfield projects — it offers compile-time safety, testability without mocking Flutter internals, and scales well from small to large feature teams. For projects with existing Bloc infrastructure or teams already trained on it, we stay in Bloc. We avoid Provider for anything beyond simple use cases due to type-safety limitations at scale. Migrating between state management approaches in Flutter is a significant refactor; we make the architecture decision explicit and documented at project kick-off so it doesn't become expensive debt.

Yes. Flutter is a rendering framework, not a backend — it communicates with whatever HTTP/REST, GraphQL, or gRPC services you already have. ABM Tech has integrated Flutter apps with SAP, Salesforce, legacy .NET and Java backends, Firebase, Supabase, and custom microservice architectures. We handle authentication flows (OAuth 2.0, SAML, biometric token refresh), offline-first sync with local SQLite or Hive storage, and file upload pipelines. The integrations are tested against your staging environment before any production deployment.

For companies with an existing web product wanting to add a companion mobile app in Flutter, the critical path is API readiness, not Flutter development. If your backend exposes clean REST or GraphQL endpoints, a mobile app covering the core user journey (login, primary workflow, notifications) typically ships in 10–14 weeks. If API work is needed first, add 4–6 weeks. ABM Tech can assign a backend engineer alongside the Flutter team to run tracks in parallel, compressing total calendar time.
