It is worth mentioning that Flutter is constantly expanded by its creator – Google. Many big brands and innovative startups trusted their mobile app vendors and decided that Flutter will be their main iOS and Android framework. There are constant discussions about the supposed superiority of either native or cross-platform development. We agree that picking mobile technology can be influenced by many factors – deadlines, project requirements, budget and particular needs of our client.
With our Flutter-dedicated content, you can learn more about its business benefits and technical details. We often get inquiries that express their interest in Flutter, but we don’t always agree it’s the best choice. Our recommendation will still be based on the analysis of the project and business goals.
So what can you find on our blog regarding Flutter mobile app development? Let’s find out!
Flutter – what is it?
The creator of Flutter – Google – wanted to provide a cross-platform technology to simplify the process of development and allow programmers to build Android and iOS apps with a single source code that will still look like native products. But how exactly does Flutter work?
First of all, it is based on an object-oriented programming language called Dart. The visual side of mobile apps is done using Material Design and changes are introduced with a hot reload feature that allows developers to see modifications within seconds. Creating something similar to a native app that will work on multiple operating systems is the goal of cross-platform technologies, including Flutter. With this framework, it’s seamless and the results look and feel fantastic.
At itCraft, we create Flutter apps for our clients that want to accelerate the app development process but don’t want to sacrifice quality. They are among many businesses that also use Flutter – including Google itself, Groupon, Alibaba Group, eBay, Philips and more. Check out our article about apps built with Flutter to find out who else decided to pick this cross-platform technology for their mobile app project.
To be up-to-date with Flutter, we provide a couple of sources you should check out. There are several places to visit if you are a developer that wants to know more about cross-platform app development. Others are more business-oriented and can guide startup owners and entrepreneurs when picking technologies and frameworks.
The official Flutter website is a great place to start. You will find information about updates and useful articles there. It’s mostly dedicated to Flutter developers who want to learn more about it or look for solutions to problems they have while coding.
Medium can also be helpful when looking for Flutter-related content. Many programmers share their knowledge on this platform. You will find insightful articles about mobile app development using Flutter – for example, this one about building performant Flutter widgets.
And, of course, there is our blog, where we regularly post articles dedicated to Flutter apps and development. We started with Flutter Review, written by one of our Android developers. That was almost two years ago and since then, many things have changed when it comes to mobile & web development. We are constantly observing IT trends to make sure we build modern solutions.
Mobile app development using Flutter – how to start?
As a framework made by Google, Flutter offers an intuitive, simple method to start Android and iOS development. We explain it in our step-by-step guide: Flutter apps – starting work with the new Google cross-platform framework. Written by one of our iOS experts, it is a complete manual that will help every dev set up the project and create a consistent, working code.
Because Flutter is a cross-platform technology, we often compare it with native languages for iOS and Android. We want to showcase all the differences – for programmers and product owners. A native app might seem like a better choice most times, but it doesn’t have to be this way. An experienced Flutter team can build a mobile app that will resemble a native solution with high performance and excellent design.
And who can be better at comparing native and cross-platform technologies than experienced Android and iOS developers? Our Flutter specialists usually coded native apps in the past. Now they also write comparison articles for our blog – where they discuss the differences between Flutter and languages like Swift or Kotlin.
Building mobile UIs – Flutter vs native Android SDK. Language and tech stack applicability and comparison – Here’s a post where our seasoned Android dev explains how Flutter and native Android development look like. He is considering all the aspects of mobile app creation in order to find out when picking one or another makes more sense.
Dart / Flutter vs Swift / Native iOS – which one is better? – A similar approach, but this time it’s all about iOS. We analyze several factors to determine if it’s better to build iOS apps using Flutter or native iOS language Swift. Can a single codebase be an advantage when creating an app for only one system? Find out in this article.
Does Flutter have any competition?
In our article, Flutter vs React Native – cross-platform frameworks comparison, we take both technologies and many different factors that are important for iOS and Android app development and try to determine which one is better. The answer is not crystal clear, which is usual when analyzing two frameworks, but we discuss all pros and cons to give you an idea of what you can expect from both.
Besides React Native and Flutter – unquestioned market leaders when it comes to single codebase development – there are other technologies that can be used for this purpose. One of them being Xamarin, created by Microsoft. We don’t use it at itCraft as we prefer Flutter and RN for their robustness, but it’s still an alternative worth knowing about.
What is this cross-platform development all about?
Why writing one code for iOS and Android became so popular? Because it can save a lot of time and be slightly cheaper than creating a separate native app for each system. Flutter apps can resemble native mobile apps but are less problematic when introducing updates and fixes – thanks to shared code and hot reload feature. But we understand you might still not be sure about cross-platform development. No worries, we have tons of content that explain all the secrets of this method, including cases when using it can be beneficial.
First of all, we would recommend an article that explains the most popular types of development – not only cross-platform and native but also hybrid and PWA. This one article will give you a general overview of the options you can get when building an app. Examples and cases of use included!
Introduction to cross-platform app development is a guidebook for people interested in iOS and Android multi-platform development that want to know all the basics. We explain how it works and compare three leading technologies – Flutter, React Native and Xamarin. It is a great place to start if you don’t know the benefits of this type of mobile development.
Besides writing blog posts, we also host webinars and create ebooks. They are full of useful knowledge and expand on the topics that are too broad to discuss in an article or a series of articles. We did a couple of pieces where we talk about cross-platform development and Flutter, so you should check them out as well.

Picking Flutter for mobile app project
Cross-platform development might seem like an option for companies with limited budget or app projects with short deadlines. But that’s not entirely true. Many established corporations and big, international brands decided to use Flutter as their primary framework. Their stories might inspire you and be proof that quality can be delivered no matter what technology is used. All you need is a skilled team of developers.
In our article about popular Flutter apps, we discuss companies that decided to trust Flutter. You probably know at least some of them. If you wonder why brands like Google, Philips, eBay, or Alibaba picked an open-source tool to build their mobile apps – these examples will explain that.
Of course, the author of Flutter is using it in several of their products, like Stadia, Google Ads and Google Assistant. They did not only create a leading cross-platform technology. Using it for their app projects proofs that Google is confident about its benefits and capabilities.
Another example of using Flutter by an established brand is eBay Motors – an app that allows eBay users to buy and sell vehicles. They described the whole process of browsing for the right technology and building an app with Flutter in their blog post. One of the main advantages they appreciate is a significantly small amount of platform-specific code – only 1.7%. For Android, it’s 0.3% and for iOS – 0.2%. That’s an impressive result that allowed eBay to speed up the development process.
Alibaba, one of the prominent Chinese e-commerce corporations, is regularly publishing articles about Flutter. They describe how their Flutter team is utilizing it to build mobile apps. They also made a YouTube video about one of their products – the Xianyu app. You will find the description of the whole process in it.
A story worth mentioning is one of the Reflectly app. You can find their blog post about React Native to Flutter migration on Medium. They started to use Flutter at the very beginning when it was still in alpha state. Despite that, they liked the possibilities it offered and decided to give it a chance. The results were more than satisfactory and the reviews were highly positive.
Small and big companies alike build their mobile apps with Flutter. Sharing the code between Android and iOS, native-like UI design and excellent performance are the advantages that can be used to provide an even better product to their customers. And every business owner wants to give their audience the value they expect.
Is Flutter suitable for app development?
Besides the main benefits of Flutter apps, there are less apparent factors we should mention. Of course, a single base of code for Android, iOS and other platforms, hot reloads that enable quick updates and excellent UI design thanks to widgets, are crucial to building successful, robust applications. But we want to discuss aspects that are often overlooked in articles about Flutter.
Let’s start with Minimum Viable Products (MVP). Flutter is definitely perfect if we want to build an initial version of our app quickly. First of all, it’s cheaper because we can test the Android and iOS versions at the same time thanks to shared code. That also means we don’t need a big team for our MVP – sometimes even one developer is enough. Minimum Viable Product is a great tool for testing the app concept before it is developed further.
If you want to learn more about MVP and its business value – check out our article: MVP app development – Lean and agile way to develop anything. All the details about Minimum Viable Product like purpose, development process and outcome are here.
Flutter is also considered a perfect match with Agile and Scrum – primary project management methodologies used in software houses for app projects. The features offered by Flutter mean that it is compatible with workflows based on values presented by Agile. Basically, it means that Flutter is excellent for productivity, rapid app development, and delivery of fantastic results when it comes to visuals and performance. To build an app with Flutter, you need just one developer team, which eliminates delays between two squads working separately on native software for Android and iOS. It is easier to manage tasks for only one team and everyone knows exactly what their role is.
Check out our article about Agile software development to find out why we use this methodology, what kind of benefits it offers and why product owners appreciate it so much. In another blog post, we also analyze the Agile Manifesto and its 12 principles to give you a better understanding of its main rules and assumptions.
