What is Flutter and why do businesses choose it?

Flutter is Google's open-source UI toolkit that enables developers to build apps for iOS, Android, web and desktop from a single codebase. Rather than two separate development teams, one for iOS and one for Android, a Flutter developer writes the application once in Dart, the programming language behind Flutter.

Build once, run everywhere

Flutter compiles directly to native ARM code and does not rely on a JavaScript bridge, unlike some alternatives. The result is apps that feel fully native but are built from a shared codebase. With features such as hot reload, developers see changes within seconds, which considerably speeds up the development cycle.

Flutter is backed by a growing community and an extensive ecosystem of packages. From state management with Riverpod or Bloc to integrations with Firebase and Supabase, the toolkit provides everything needed for professional app development. Where native code is required for specific platform features, Flutter offers platform channels as a bridge to iOS and Android-specific APIs.

Our development process

From first idea to publication on the App Store and Google Play, we guide you through the entire journey. Our approach is agile: we work in short sprints so you see results quickly and we can adjust course along the way.

1
Discovery
We map out your target audience, use cases and technical requirements. Together, we'll define the scope and priorities for your Flutter app.
2
Design & prototype
Our UX designers create wireframes and interactive prototypes in Figma. You see the app before a single line of code is written.
3
Development
Our Flutter developers build the app in sprints. Thanks to hot reload and widget-based development, you see working functionality with every sprint.
4
Launch & maintenance
We handle publication to the App Store and Google Play, including CI/CD pipelines, monitoring and ongoing maintenance after launch.

What we build with Flutter

From an initial MVP to enterprise-grade applications, Flutter is versatile enough for a wide range of projects. Below are the types of apps we regularly develop.

MVP & prototype

MVP & prototype development

Want to validate an idea quickly? Flutter is ideal for getting a working minimum viable product up and running in a short time. One codebase for both platforms means you reach the market faster and get feedback from real users sooner.

Consumer apps

Consumer apps (B2C)

B2C apps for iOS and Android with a focus on user experience. From onboarding flows and push notifications to in-app purchases and social features, we build apps your users will love opening.

Enterprise

Enterprise apps (B2B)

Complex business applications with authentication, role-based access, offline-first functionality and integrations with existing business software. Built for reliability and scalability.

E-commerce

E-commerce apps

Mobile shopping experiences with product catalogues, payment integrations (Mollie, Stripe, iDEAL), push notifications for offers and a smooth checkout process that maximises conversion.

IoT & dashboards

IoT & dashboard apps

Real-time monitoring of sensor data, connected devices and business processes. Flutter's fast rendering makes it ideal for dashboards that display large volumes of data visually.

Migration

Migration to Flutter

Looking to convert existing native iOS or Android apps to Flutter? We analyse your current app, plan the migration and ensure a smooth transition without loss of functionality or downtime for your users.

Flutter for your industry

Flutter suits almost every sector. The combination of rapid development and native performance makes the framework especially valuable for organisations that need to move quickly.

Startups & scale-ups

Startups & scale-ups

Rapid market validation with a cross-platform MVP. Flutter enables startups to launch a professional app on both platforms on a limited budget. Ideal for testing assumptions, convincing investors and iterating quickly based on user feedback.

E-commerce & retail

E-commerce & retail

Mobile shopping experiences that convert. From product browsing and wishlist functionality to seamless checkout flows with Dutch payment methods. Flutter's fast rendering delivers smooth animations and the premium feel customers expect.

Healthcare

Healthcare

Patient portals, appointment systems and medical apps that meet strict privacy requirements. Flutter combines an intuitive user interface with the ability to store data securely and encrypt it, which is essential in the healthcare sector.

Logistics & transport

Logistics & transport

Track & trace applications, driver apps and planning tools that also work offline. Flutter's offline-first capabilities and GPS integration make it well suited to field workers who don't always have a network connection.

Our Flutter tech stack

We work with a proven set of tools and frameworks that together form a solid foundation for every Flutter application, from state management and backend integrations to automated deployment pipelines.

  • Riverpod and Bloc for predictable state management
  • Firebase and Supabase as backend-as-a-service
  • REST API and GraphQL for custom backend integrations
  • SQLite and Hive for local and offline data storage
  • CI/CD via GitHub Actions and Fastlane for automated builds
  • Material Design 3 and Cupertino widgets for platform-native UI

Why choose Appfront for Flutter development?

Getting a Flutter app built is more than writing code. It takes a team that oversees the entire process, from UX design and architecture through to publication and ongoing maintenance. That's why at Appfront you work with a dedicated team that guides your project from start to finish.

Cross-platform efficiency

One codebase for iOS, Android and the web. This means less development time, lower costs and a consistent user experience on every device. Changes and updates only need to be made once.

Rapid development cycle

Flutter's hot reload and widget-based architecture allow our developers to iterate quickly. You see working functionality along the way and can steer the project early on, without putting pressure on the schedule.

Native performance

Flutter compiles to ARM code and runs without bridge overhead. The result: 60fps animations, fast start-up times and a user experience that is indistinguishable from fully native apps.

Frequently asked questions about Flutter development

What is Flutter and why do businesses choose it? +
Flutter is Google's open-source framework for cross-platform app development. With a single Dart codebase, you build apps for iOS, Android, web and desktop. Businesses choose Flutter for its shorter development time, lower costs and the ability to deliver a consistent user experience across all platforms without maintaining separate teams.
Is Flutter suitable for enterprise applications? +
Yes. Flutter is used by large organisations such as BMW, Google Pay and Alibaba. The framework supports complex architectures, offline-first functionality, role-based access and integrations with enterprise systems via REST APIs and GraphQL. State management solutions such as Riverpod and Bloc make it well suited to large-scale, maintainable applications.
What is the difference between Flutter and native development? +
With native development, you write separate code for iOS (Swift) and Android (Kotlin). Flutter uses a shared codebase for both platforms, which reduces development time and maintenance costs. Flutter compiles to native ARM code, so performance is comparable to native apps. The difference lies mainly in cost and time to market, not in the end result.
How long does it take to build a Flutter app? +
The timeline depends on the complexity and scope. An MVP can be ready within a few weeks, while a full enterprise app with integrations and extensive functionality may take several months. We work in sprints so you see progress along the way and can steer the project together with us.
What types of apps do you build with Flutter? +
We build a broad range of apps: from MVPs and consumer apps to enterprise applications, e-commerce apps, IoT dashboards and internal business tools. We also migrate existing native apps to Flutter. Your specific requirements, target audience and budget determine whether Flutter is the right choice.
What determines the cost of a Flutter app? +
The cost depends on factors such as the number of screens and features, the complexity of integrations with external systems, the level of UX design required, whether offline functionality is needed and the degree of custom development. Because Flutter uses a shared codebase, costs are usually lower than fully native development for both platforms.
Can you migrate an existing app to Flutter? +
Yes. We analyse your existing iOS or Android app, map out all features and dependencies, and plan a phased migration. This lets you transition step by step without downtime for your users. After migration, you benefit from a single codebase for future maintenance and extensions.
What about app store publication and maintenance? +
We handle the entire publication process for both the Apple App Store and the Google Play Store, including setting up developer accounts, submitting the app and getting through the review process. After launch, we provide ongoing maintenance: updates for new OS versions, bug fixes, performance optimisation and the addition of new features.
