IoT with Flutter: Building Smart Connections

In this blog, we'll explore why Flutter is a great option for developing IoT-supporting applications.

Published by Hamish Kerry

In the age of the Internet of Things (IoT), where everyday objects are becoming smarter and more connected, mobile app development platforms like Flutter are playing a pivotal role in creating user-friendly interfaces for controlling and monitoring IoT devices. Flutter's cross-platform capabilities and rich widget library make it an excellent choice for developing IoT applications that can run on both iOS and Android devices. In this blog, we'll explore why Flutter is a great option for developing IoT-supporting applications.

Understanding IoT and Its Applications

IoT is all about connecting physical objects and devices to the internet, allowing them to send and receive data, communicate with each other, and interact with users through mobile apps or web interfaces. IoT applications are diverse and can include smart home automation, industrial monitoring, healthcare devices, and more. Experts suggest the number of IoT-connected devices could reach 22 billion by 2025 (Oracle).

The core components of an IoT ecosystem include:

  • IoT Devices

  • Connectivity

  • Cloud Services

  • User Interfaces

Why is Internet of Things (IoT) so important?

Over the past few years, IoT has become one of the most important technologies of the 21st century. Now that we can connect everyday objects including kitchen appliances, cars, thermostats and baby monitors to the internet via embedded devices, seamless communication is possible between people, processes, and things.

By means of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention. In this hyperconnected world, digital systems can record, monitor, and adjust each interaction between connected things. The physical world meets the digital world—and they cooperate.

Streamlined Development with Flutter for IoT:

In the realm of IoT, where rapid iteration and responsiveness are paramount, Flutter's hallmark feature, hot reload, proves to be a game-changer in the development process. It allows IoT developers to make real-time code changes without restarting the application, enabling them to swiftly iterate on their IoT applications. 

This agile development approach is essential for refining features, enhancing usability, and addressing evolving IoT requirements with unparalleled speed and efficiency. With Flutter's seamless integration into IoT development workflows, teams can respond rapidly to user feedback and evolving market demands, ensuring that IoT applications stay ahead in the dynamic landscape of connected devices and systems.

Cross-Platform Compatibility for IoT Solutions:

Flutter's ability to create a single codebase that seamlessly runs on multiple platforms is particularly advantageous in the IoT domain. Whether it's iOS, Android, web, or desktop, Flutter ensures a consistent user experience across a diverse array of IoT devices. This cross-platform compatibility streamlines development efforts for IoT applications, eliminating the need for separate codebases and reducing maintenance overhead. 

By leveraging Flutter's capabilities, organisations can reach a wider audience and maximise the market potential of their IoT solutions without compromising on quality or efficiency. In the interconnected world of IoT, where devices communicate seamlessly across platforms, Flutter's cross-platform compatibility is a valuable asset for delivering cohesive and unified user experiences.

Consistency in UI/UX Design for IoT Applications:

In the IoT landscape, where user interfaces play a crucial role in facilitating interactions between users and connected devices, Flutter's rich widget library and customisable components empower developers to create visually stunning interfaces tailored for IoT applications. This consistency in design not only enhances brand identity but also fosters familiarity among IoT users, driving adoption and retention. 

Whether users access IoT applications on smartphones, tablets, or desktop computers, Flutter ensures a seamless and optimised experience, enhancing usability and user satisfaction. In the ever-expanding ecosystem of IoT devices, where diverse form factors and screen sizes are prevalent, Flutter's capabilities in delivering consistent UI/UX design across platforms are instrumental in creating intuitive and engaging IoT experiences.

Cost-Effective Solutions with Flutter for IoT:

Flutter's single codebase approach offers significant cost savings for organisations developing IoT solutions. By writing code once and deploying it everywhere, organisations can minimise development costs and resource overheads associated with maintaining multiple codebases for different platforms. This cost-effective solution empowers startups and enterprises alike to innovate quickly and scale their IoT offerings efficiently. 

With Flutter, organisations can invest resources wisely, driving growth and competitiveness in the IoT market while maximising return on investment. In the fast-paced world of IoT innovation, where agility and cost-effectiveness are key success factors, Flutter's capabilities in delivering cost-effective solutions for IoT development are invaluable for organisations looking to thrive in the interconnected future of IoT.

Seamless Integration with IoT Devices:

Flutter's seamless integration capabilities facilitate robust communication between IoT devices and applications. Whether it's collecting sensor data, controlling smart devices, or analysing real-time insights, Flutter enables developers to seamlessly integrate IoT functionalities into their applications. 

This interoperability enhances the utility of IoT products and enables users to harness the full potential of connected devices in their daily lives. With Flutter, organisations can create cohesive and interconnected ecosystems that deliver value and enhance user experiences.

Real World Applications: 

Flutter has been utilised in many instances for IoT apps, by some of the biggest brands in the world across a range of industries. 

My BMW App in use

BMW for example, utilised Flutter when it came to creating their app for the My BMW app, which allows users to connect with their vehicles, viewing key performance stats and even access primary car functionality.

iRobot helped bring new fun to their range of floor cleaning robots with the introduction of the iRobot Coding App, which helps engage kids in STEM by allowing them to pilot their vacuums with code. 

Philips utilises Flutter for their primary app for controlling their range of “hue” lighting fixtures and bulbs. The app is sleek to use, allowing their customers to control all aspects of their home's ambience. 



Flutter revolutionises IoT app development with its rapid iteration, cross-platform compatibility, and cost-effective solutions. Its hot reload feature accelerates development, ensuring responsiveness to evolving IoT requirements. By creating a single codebase for multiple platforms, Flutter reduces maintenance and maximizes market reach. With rich UI customization, it enhances user experience across diverse devices. Seamless integration capabilities empower developers to create cohesive IoT ecosystems, driving value and enhancing user experiences in the interconnected world of IoT.
