You’ve probably used products built by our Dart developers.
From cross-platform mobile apps to large-scale product interfaces, our Dart teams build and support applications that hold up under real usage. We fix structural and performance issues that slow delivery, so release timelines stay predictable as products scale across platforms.
Maintaining separate mobile and web codebases slows feature delivery and increases overhead. We deliver cross-platform app development using the Dart programming language to build applications for iOS, Android, and web platforms from a shared codebase. We keep clear boundaries between UI, state, and business logic so the app stays easy to change. This accelerates development and gives your teams a single, reliable foundation for scalable front end development.
Dropped frames, slow startup times, and memory pressure erode user trust as usage grows. We profile Dart applications to pinpoint rendering inefficiencies, state management problems, and runtime resource bottlenecks. Then we apply targeted fixes and validate them under realistic load. The result is consistent performance and the ability to create high performance applications without destabilizing the broader system.
Aging mobile and web front ends become difficult to extend, test, and release safely. We modernize enterprise app development efforts by re-platforming client layers in Dart while preserving core business logic and existing backend integrations. This approach supports fast development cycles while keeping active users and business requirements fully intact.
As features accumulate, tightly coupled UI code increases regression risk and slows delivery. We design scalable Dart UI architectures with reusable components, predictable state patterns, and clear ownership boundaries. This structure supports complex UIs and visually appealing user interfaces while allowing teams to ship changes confidently as product scope grows.
Fragmented client and server codebases increase duplication and slow iteration. We handle server side development in Dart selectively, where shared models, validation logic, or asynchronous programming patterns benefit from alignment with the client layer. These services integrate seamlessly with existing backend systems, reducing redundancy without replacing established enterprise backends or related technologies.
Maintaining native or JavaScript-based implementations across platforms drains engineering capacity. We migrate existing web and mobile applications to Dart, managing code conversion, dependency replacement, testing, and phased rollout. So your team can reduce duplicated work across platforms and move toward a unified application stack without derailing delivery timelines.

1480+ projects successfully delivered.
Our track record means you get software that meets the highest technical and business standards.
Google needed senior QA engineers to maintain quality at scale. We embedded senior QA engineers across Android TV and YouTube. During the Android TV launch, we delivered stand-alone and integrated testing to fix bugs and improve seamless user experiences, then expanded support across five QA teams. By replacing manual testing with automated processes, we improved scalability while maintaining a consistent experience across devices and platforms.
Rolls-Royce’s MSDS platform only worked on-site, so teams outside the control room couldn’t monitor safety data in real time. We extended it beyond the control room with mobile, real-time safety monitoring by reusing the existing web codebase and shipping a Progressive Web App MVP with a 5-person team. The PWA delivered real-time alerts and offline access without app stores, so plant admins could track safety data from anywhere.
AP needed to modernize a legacy Classic ASP news platform, so content could flow to web, mobile apps, and social without disrupting daily publishing. We staffed vetted engineers, kept the current system running, and migrated nearly 20 sections to a .NET CMS. We also moved archives dating to 1985 (3.65M stories) and surfaced ~40M photos and 2M videos. The platform now supports omnichannel delivery for 1.5M app users and 56M+ followers.
The ecosystem we use for Dart projects:
We work within the mature Dart ecosystem and Flutter framework to support cross-platform development that scales, stays maintainable, and supports predictable release cycles as products grow.
Application Frameworks
We build production Flutter applications using Dart for iOS, Android, web, and desktop. We use Flutter to share core logic and services across platforms while adapting layouts and input patterns for different screens and devices. This reduces duplicated work and keeps behavior consistent as the app scales.
State Management & Application Architecture
As Dart applications grow, unmanaged state quickly becomes a delivery risk. We implement proven state management patterns that keep UI logic predictable, testable, and scalable within the overall development process. This structure supports complex user flows and interactive user experiences without introducing regressions or brittle dependencies.
Backend & API Frameworks
When Dart is used on the server, we use frameworks that support API development, middleware, and auth. This can be a good fit when shared models or validation logic reduce client/server drift. We integrate with existing backend systems so you reduce duplication without replacing established enterprise backends.
Testing & Quality Assurance
Reliable Dart applications require disciplined testing across logic, UI, and integration points. We use Dart’s native testing tools to validate behavior early and protect delivery timelines as complexity grows.
Performance & Debugging
Performance issues in Dart applications often surface only under real usage. We rely on profiling and diagnostics tools from Dart DevTools to analyze rendering behavior, memory usage, and runtime performance.
Build, CI/CD & Release Automation
Shipping Dart applications across multiple platforms requires repeatable, automated pipelines. We integrate Dart builds into existing CI/CD workflows so releases remain consistent, auditable, and aligned with internal delivery standards.
Platform Integrations & Native Interop
Some functionality requires direct access to platform-specific APIs. We use Dart’s native interoperability capabilities to integrate with iOS, Android, and web features without compromising application structure or stability, including cases where native JavaScript or platform SDKs are required.
We build production Flutter applications using Dart for iOS, Android, web, and desktop. We use Flutter to share core logic and services across platforms while adapting layouts and input patterns for different screens and devices. This reduces duplicated work and keeps behavior consistent as the app scales.
