Cross-Platform Flutter Media App for the World’s Largest Cinematic Image Database
The application is the industry’s premier research tool, housing the world’s largest library of fully searchable, high-definition movie images. We developed a high-performance, cross-platform software using Flutter and Dart to provide a seamless discovery and playback experience across Web, iOS, and Android from a single, scalable codebase.

Highlights
- Cross-platform Flutter app development for Web, iOS & Android
- Legacy app migration into a unified, scalable media platform
- Custom video player development with adaptive streaming previews
- SEO-optimized Flutter web app for stronger organic search visibility
Challenge
Before the migration, the client struggled with three separate codebases (Kotlin for Android, Swift for iOS, and Ajax/JS/PHP for Web), each with inconsistent logic and high maintenance costs.
Specific obstacles included:
- Unifying the codebase without losing native performance.
- Safely migrating thousands of users, incl. enterprise accounts and metadata from an old version of the app to a new one.
- Efficiently handling heavy media content (millions of high-res stills and video previews) across devices.
- Integrating complex authentication (Apple, Google, Okta) and Stripe payments in a cross-platform environment.
Solution & functionality
We engineered a unified Flutter application that replaced fragmented legacy systems with a single source of truth, combining scalable architecture, advanced navigation, custom media playback, and optimized performance across Web, iOS and Android.
The system combines custom media playback, robust caching, and scalable state management to ensure seamless browsing, stable performance, and consistent functionality across web and mobile platforms.
The unified application was designed to support advanced media discovery with responsive layouts, deep linking, URL-based search, and smooth interaction across large image and video libraries.
A single Flutter codebase unified Web, iOS, and Android into one scalable product with consistent performance.
Deep linking, URL-based navigation, and SEO-ready architecture improved content discoverability across the web experience.
A custom media engine with thumbnail previews, adaptive streaming, and smart caching ensured smooth playback of rich visual content.
Secure user migration and integrations with Stripe, Okta, Firebase, Apple, and Google enabled a frictionless transition to the new platform.
Cross-Platform Media Experience
Built with Flutter for iOS and Android, this mobile solution combines responsive navigation, scalable Bloc/Cubit state management, custom caching for large media libraries, and a bespoke video player with thumbnail previews and adaptive streaming.
The result is a smooth, feature-rich user experience designed for performance, consistency, and long-term scalability.
