Insights from a Tech Lead
I've spent the better part of my career immersed in code, late-night deployments, and architecture debates, all while navigating the relentless wave of tech updates that seem to roll in every quarter. If you've ever worked on enterprise-scale eCommerce projects, you’ll know this reality well, the right mobile development approach can be the difference between a high-performing app that fuels revenue and one that frustrates users and drains resources.
When you're building for enterprise, you're not just shipping something that looks good in the app store. You're building for user engagement, conversion rates, brand equity, and technical scalability, especially for peak traffic days like Black Friday or Boxing Day. These are high-stakes decisions, and they deserve more than surface-level consideration.
Over the past decade, the conversation around mobile development has shifted dramatically. Enterprises were laser-focused on native development being the gold standard (Swift for iOS, Kotlin for Android). That approach is still a valid strategy in some scenarios, particularly if you need the utmost control over hardware or want custom animations that doesn’t risk lag or jitter under any circumstance. However, this approach comes at a high cost both financially and in development time. Maintaining two separate teams and codebases can be resource intensive, especially if you aim to release new features simultaneously.
Meanwhile, React Native was an early disrupter with its promise of “learn once, write anywhere,” but it hasn’t always been smooth sailing given performance trade-offs and dependency overlaps.
Then Flutter came along. At first, people were a bit skeptical of this shiny new framework from Google. “What’s Dart?” they asked. “Will it be another experimental flash in the pan?” Fast-forward to 2025, and it’s hard to ignore Flutter’s rise. The ecosystem has become massive, counting over 2 million developers worldwide, the community support is bustling, and those early performance concerns have melted away. In fact, for many eCommerce businesses, Flutter’s single codebase approach and tight integration with Skia’s rendering engine have proven to be a game-changer. The performance is, in many cases, on par with native apps, especially on modern devices, and you’re not juggling two or three separate codebases every time someone from marketing wants to tweak the product listing page or introduce a new loyalty program feature.
As a Tech Lead, I’m regularly asked to weigh up native vs. React Native vs. Flutter because nobody has an unlimited budget or an endless supply of developers with every possible expertise under their belt. Here’s what I typically consider;
Some CTOs still question the need for a mobile app, especially if their web experience is fully responsive. But even the most meticulously designed mobile web experience can’t replicate the deeper engagement you can achieve with an installed app. You get to leverage push notifications for abandoned cart nudges, instant access to the phone’s camera for product scanning or easy returns, and more advanced personalisation that can factor in everything from location data to user behavior across sessions - all critical for staying competitive in eCommerce. This is especially relevant when you want to innovate quickly, for instances such as a flash sale or testing out a new AR-based shopping feature and rely on deeper system hooks that a browser can’t provide.
Building at scale is never just about the tech. Communication between teams (backend, mobile, design) is crucial. Misalignment can derail timelines. Hiring is another concern, finding experienced Flutter or Kotlin developers isn’t always easy. Outsourcing brings risks too - unclear handoffs, proprietary codebases, and integration issues with legacy systems.
Plan for scale and security from day one. Whether it’s load balancing, analytics integration, or compliance with data privacy laws, your architecture should support these from the outset. Don’t bolt on encryption as an afterthought. Make sure the stack you choose supports your broader ecosystem - CRMs, payment gateways, marketing automation, and analytics.

In my experience, Flutter has increasingly become the “safe bet” for large-scale eCommerce. It’s agile, which means fast release cycles and the opportunity to test new features or promotions without going through disjointed development phases. It’s relatively cost-effective, allowing you to centralise your efforts. And it’s backed by a strong community and Google’s consistent release schedule, which helps ensure you’re not left behind if a new version of iOS or Android rolls out. There’s also the not-so-small matter of developer happiness, many engineers appreciate the cohesive nature of Flutter, the built-in widget set of 300+ for both iOS and Android platforms, and the reassuring stability of the platform (7 years of maturity).
Yet, the truth is that no framework is a silver bullet. If your app is strictly about pushing the limits of hardware integration, maybe to build the next big AR game or a specialised medical imaging tool, then native might remain your best friend, leading for specialised use cases. React Native remains viable for teams already embedded in the JavaScript ecosystem. But for most enterprise eCommerce goals, speed, scalability, consistent UX, and cost-efficiency - Flutter often ticks the most boxes.
Ultimately, A well-built mobile app is far more than a line item in your budget or a short-lived marketing channel. Even in 2025, picking the right mobile tech stack remains one of the most strategic decisions you’ll make. It is an essential tool for creating meaningful customer touchpoints, building brand loyalty, and staying competitive in a market that’s constantly evolving. Whether you’re leaning toward fully native development, sticking with React Native, or finally jumping on the Flutter bandwagon, make sure your choices align with your core business goals and your team’s capacity to execute at scale.
Having seen multiple eCommerce projects through from idea to launch, I can say this with confidence, Flutter has consistently delivered results that balance performance, developer efficiency, and business impact. It offers near-native performance while eliminating the pain of duplicated efforts.
Pick the path that suits your organisation’s DNA. Technology is just one part of it. The right vision, processes, and team culture will help brings the best out of any tech-stack and you’ll be well on your way to building an app that genuinely delights your customers, drives up those cart values, and keeps your brand in a prime position for whatever tomorrow brings.
