Flutter is Perfect for IoT Apps

About Flutter

Flutter is a young and rapidly evolving project by Google. It is a complete software development kit (SDK) that allows you to create functional cross-platform applications for mobile, web, and desktop.


I would say at this point that Flutter is a perfect tool for creating companion apps for Internet-of-Things (IoT) devices.

Types of IoT connections, architecture, and networks

The IoT system has three-tier architecture: devices, gateways, and data systems. Data circulates between those levels through four types of transmission channels.

                                                            Types of IoT connections- architecture- and networks
Connection types

1. Device to Device – direct contact between 2 smart devices;
2. Device to Gateway – data transfer between gateway and sensor;
3. Gateway to Data systems – data transfer from the gateway to the data cloud;
4. Between Data systems.

The benefit of IoT development

  • Fast development
  • Reduced cost
  • Native performance
  • High performance
  • Custom UI
  • Gamification-friendly
  • Synched launch
  • Faster deployment
  • High productivity
  • Fast development

As a rule, the goal of using any cross-platform technology will speed up the development process. In the case of Flutter mobile app development, you write a codebase that can run on iOS and Android both devices.

That doesn’t mean you cut growth time in half compared to native development.
It always takes more time to slow down the edges and make sure everything renders like that on both platforms. But it can reduce the development team by 70% 

  • Reduced cost

Decreased growth and a small team imply serious savings. For some businesses, this means more convenient budgets and the opportunity to implement more features for less money. For companies with limited resources, cross-platform development may be the only opportunity to kick-off in the first place.This is one of the reasons why Flutter Mobile Development is such a perfect fit for MVP and PoC projects.

  • Native performance 

Just because it's not native doesn't mean it should be discontinued.In fact, one of the reasons why Google's flutter Terry has won so many hearts is the beautiful native performance it provides.

When it comes to mobile application development, the Flutter Toolkit added every possible plugin, component, and widget needed to recreate the original Android and iOS look and feel.

  • High Performance

Just because it’s not native, doesn’t mean it should perform poorly. Flutters are always compared to the more mature cross-platform framework React Native. Performance, by a large margin, is a measure of the flutter beats react.

The flutter engine was built to communicate directly with the native modules, resulting in good high speed and performance. Using Flutter, you can create a small application, a mobile platform that streams video, or a data-heavy IoT application. They will perform high and equally stable.

  • Custom UI

The flutter is design-friendly. It is difficult to imagine a mobile user interface that you would not be able to implement using the resources of this platform. There are many libraries and tools in any case, including Cupertino widgets and material design. Everything is customizable. And it goes without saying that you create two mobile applications using a single UI design.

  • Gamification-friendly

Gamification is a rapidly evolving technological trend. It was most popular in the e-learning applications of entertainment, fitness, and gambling. Nowadays, gamification elements are integrated into all types of consumer applications including banking,e-commerce, utilities, etc.

Flutter allows developers to add gamification features, Apply a gamified interface to mobile apps and ensure adequate operation and speed. There are already many successful examples of stores. The new game streaming project Stadia, introduced by Google this year, has also been built on Flutter.

  • Synched launch

So we have a team, a codebase, and numerous tools, plugins, and libraries to develop applications quickly and efficiently. 

Creating a mobile app for two platforms simultaneously means you can deploy both apps and launch them without any gaps.

  • Faster deployment

As a modern cross-platform project, Flutter software provides software and QA engineers with a wide range of tools for functional development environments and optimized debugging and testing.

Hot reload features, for example, allow engineers to instantly update code, review changes almost in real-time, test and deploy applications more easily and quickly.

  • High productivity

Flutter mobile app development is a real deal for expandable projects.Flutter applications are created using Dart - an object-oriented programming language.It is improved, has unruly syntax, and is understood by JavaScript and Java developers.

Most importantly, DART code is used not only on iOS and Android but also run for web apps and desktop app. To date, Flutter's offer for desktop and web is limited and apps are not as stable as mobile versions.

  • Building IoT apps with Flutter

If you’ve ever set up a smart device like  Amazon Alexa, Google Home, Philips Hue Light Bulbs, or Smart Switch, you know the general requirements for the IoT Companion app.

The application needs to be connected to the nearest device, connected to it, and configured.

Sometimes this happens over Bluetooth, sometimes over Wi-Fi, and sometimes through the wacky sequence of strobing lights.    

Our application in this regard is not much different. Users need to connect to Tidbite and configure it with their password and Wi-Fi SSID.  But while creating the application we found two things there:    
First of all

Pairing up and setting up Bluetooth Lay is easier than a Wi-Fi virtual AP. Switching back and forth between Wi-Fi networks can be conflicting and often requires user intervention. Bluetooth LE has a very simple "just works" experience.


Flutter does not have Bluetooth support built-in, so it is important to choose the right third-party Bluetooth plugin. There are many corner cases when interacting with the native Bluetooth API, and the plugin needs to handle this properly.

We initially chose Flutter_Blue but participated in a number of difficult-to-reproduction issues. We ended up switching to flutter_ble_lib. The latter is built on top of RxAndroidBle  and RxBluetoothKit , which are solid and widely deployed native library.

First and foremost, Flutter reduces the effort to free both Android and iOS. Having a single codebase for both platforms speeds up productivity in implementing UI.
Another benefit of flutter is a bit more subtle. Because of the way it works, Flutter is relatively easy for many background engineers to choose. Because of this, anyone on a small team can contribute to the Flutter application.

Applications are written to Dart and all tooling filters are CLI. Included in,  
Dart is its own language, but its syntax is easily sufficient if you come from a C, Java, or JavaScript background. Having well-integrated widgets and tooling makes it fast to bootstrap, build and execute projects. Especially if you come from a backend or firmware engineering background, this makes it much quicker to choose a flutter.
