Flutter mobile app development

Flutter semi-native mobile app development

Google's toolkit lets you develop with the maximum flexibility and speed.

Flutter is the Google toolkit that allows you to create native applications for Android and iOS mobile devices, web and desktop using a single code base, making the development process more fluid and effective.

If you are looking for an option to quickly develop applications for iOS and Android with great value for money, Flutter is definitely an option to consider.

Its flexibility and responsiveness is making it one of the most used frameworks by companies all over the world: among the major companies that use flutter we find Google, Alibaba, Square and Ebay.

One of our projects created in Flutter is the Gluto app for celiacs, reviewed by the official Flutter website and listed on our portfolio.

One of Flutter's defining characteristics is its approach to creating user interfaces, which uses a programming language called Dart. Dart enables developers to create mobile apps, which code runs directly on the user's device without the need for interpretation or conversion.

This approach offers several advantages. First, it enables developers to achieve native performance and a smooth and responsive user experience. Thanks to its widget-based architecture, Flutter offers complete control over the look and behavior of the user interface, ensuring visual consistency across different platforms. Additionally, Flutter simplifies building cross-platform apps by allowing developers to write code once and run it on multiple operating systems.

This reduces the time and effort required to develop and maintain apps across platforms, allowing for a greater focus on quality and innovation. Another strong point of Flutter is its rich collection of pre-built widgets and libraries. This allows developers to speed up the development process by using out-of-the-box components to handle layouts, animations, user input, and more. Additionally, the developer community around Flutter is constantly growing, offering active support and a wealth of resources. In conclusion, Flutter is establishing itself as a highly relevant seminal mobile app development framework. With its ability to deliver smooth, high-performance user experiences across platforms, simplify cross-platform development, and offer a large collection of widgets and libraries, Flutter is an ideal choice for building high-quality, successful mobile apps.

The main benefits of using Flutter are:

Faster development thanks to a rich set of fully customizable widgets

Detailed customization thanks to Flutter's layered architecture

Incredibly fast loading performance

Native performance thanks to widgets that embed the critical differences between the Android and iOS operating systems

Incredible care of the end user experience

How does glueglue work and what are your areas of expertise?

We start with an in‑depth needs analysis, considering product and business objectives in the medium to long term. We often begin with visual identity: we assess positioning, analyze competitors, and identify opportunities to improve brand and image. We then move to UX/UI: we conduct a professional UX Review to identify areas for intervention and improve the usability of the site or app. We design the User Journey Map, mapping all touchpoints to understand real use cases and where to create tangible value. We create wireframes and share an interactive prototype that defines the functionality, structure, and interactions of each page. Once the wireframes are consolidated, we refine the interface design in detail to ensure a pleasant and consistent experience. Finally, our developers implement the product with modern technologies such as React, Flutter, Symfony, Svelte, Node.js, and more, ensuring quality, stability, and pixel‑perfect results.

Do you use artificial intelligence?

Yes, on two fronts. Inside our own method, where it helps designers explore and compare several directions in hours instead of days, and helps engineers accelerate repetitive phases and raise quality with broader review and testing.
And inside the products we build for our clients: document and file analysis, predictive models, understanding of unstructured text, semantic search, assistants and automations.
For us it is a multiplier, not a shortcut: people stay in the loop and every AI feature has a success metric defined before it is written. Read how we use AI.

How much does it cost to entrust you with a digital project?

We believe in transparency: talking openly about budget helps create value for both sides. Every client has different needs, which is why we don’t use a fixed price list. Instead, we take the time to understand the context and propose a tailored approach with a fair, appropriate investment. Our UX/UI design projects start at €15,000, while branding engagements begin at €8,000. Mobile app development typically requires an investment starting from €40,000, web apps from €30,000, and websites from €15,000. Our average hourly rate for consulting is €70/hour.
