We Speak from Experience

In one of our previous projects, we hit a bit of a snag with some outdated tech. The client was very keen and excited to work with Dart and chose Flutter and Aqueduct as their preferred tech stacks. Aqueduct, a Dart-based backend framework, became obsolete without warning. We had to do a complete project revamp, swapping out Aqueduct for a different backend framework.

When Flutter initially entered the market, features like Google Maps integration and location tracking seemed complex, with limited documentation and support available. While we were excited about exploring this new framework, we ultimately had to discontinue its use due to location-based features and navigation challenges. In other instances, when considering a migration from React Native to Flutter, we observed the importance of factors such as Web Support, Null Safety, Flutter DevTools, a robust Plugin Ecosystem, and Animation and Graphics capabilities.

In the past, we used React.js to develop e-commerce applications due to its seamless integration and performance. However, with the emergence of Next.js, which bridges the gap between business and development, we found a tool that greatly accelerated business growth. Today, when we aim to build a web app that requires SEO-friendly pages to enhance sales and market presence, we opt for Next.js. This strategic choice has consistently resulted in high client satisfaction and improved business outcomes.
