To create visually appealing, multi-platform, and natively compiled applications with the use of one codebase, Flutter is the best option as an open-source framework. It provides a productive workflow, flexible and fast, and enables complete control over every pixel for a gorgeous outcome of adaptive and customizable designs.
Flutter enables simple and easy deployment to all embedded devices, not just mobile, desktop, and web. Also, the workflow is simplified and more efficient through total control of the codebase through tooling for developers, automated testing, and all features and perks that lead to top-quality applications created.
Google also uses and supports Flutter, making this framework a favorable one globally and supported by a large community of brands and developers.
Demand for Flutter developers and stats
Since Flutter as a framework is relatively new, the demand for Flutter developers is steady or rising to keep up with the novelties and benefits in the tech world whenever introduced.
Because Flutter is a functional, reliable, and efficient framework, its demand rises constantly. Finding a suitable fit is also getting more manageable and time-saving because the community of Flutter experts is continuously enlarging, saving everybody some time—from employers to developers seeking a job.
A survey from Statista has shown that between 2019 and 2021, Flutter was the most popularly used for cross-platform development, with a substantial percentage of 42%, and the rise continues at a steady pace.
What exactly does a Flutter developer do?
Why and when do you need to hire a Flutter developer?
Hiring one or more Flutter developers is your go-to option when something needs completion quickly. When the developer finishes the work, the launch of a finished product goes speedily and almost immediately. Whether you choose a single hire or a team, Flutter developers can finalize something with excellent results within a quick timeframe.
Interviewing a Flutter developer
Helpful tips for a pre-screening interview
The first and crucial step in hiring a Flutter developer is made by recruiters and experts who organize and do the interview, but this process needs meticulous planning beforehand. Like any other hiring process, in this case, the Flutter developer has to meet all criteria for the company.
The process is familiar to everyone—it starts with essential getting to know each other through questions specific to the job position. After this, the following steps are more specific questions, or in most cases, tasks and practical tests of the skills.
Almost all hiring specialists are on the same page when it comes to hiring developers, or more precisely, in this case, Flutter developers.
The ideal candidate will have good experience and soft skills; the more, the better. Any developer that would enter a new workplace and team has to communicate well with the other team members because miscommunications could be an obstacle to the workflow. Also, the candidate has to be polite, respectful, and have a good knowledge of the English language.
Top technical skills to look for in a Flutter developer
An excellent Flutter developer has to attain various technical skills for practicality and functionality. Hiring, in this case, becomes even more intriguing because Flutter is a new framework to some extent, and perhaps a handful of developers would be the best match out of numerous applicants.
A great Flutter developer will primarily know how to:
- Fix bugs efficiently
- Write a clean code
- Investigate technologies for fast development
- Take part in life-cycle development
- Be up to date with the latest development trends
- Develop and design apps
However, as we delve deeper into the technical skills of a Flutter developer, without exception, there needs also to be:
- Knowledge and experience with the Flutter framework
- In-depth expertise and knowledge of Git
- Understanding of software development life-cycle
- Dart programming language experience
- Expertise in iOS or Android mobile development services
- Quality knowledge of Computer Science
- GoF patterns experience
- Architecture approaches experience
- SQL expertise
- Knowledge of Swift and Kotlin
We asked Zoran Conevski, a full stack developer, to share some of the expert technical skills a Flutter developer should have. He says:
“Good knowledge in software architecture is crucial and knowledge in Dart and system design. Hand in hand with this, it is a must-have for a Flutter developer to know how to set up the suitable and proper app architecture, which makes the project maintainable and easy for usage and control in the long run. Additionally, Dart and Flutter's best practices are desirable, especially regarding optimization and performance”.
What sets apart a great Flutter developer from a good one?
A great Flutter developer differentiates from a good one, adds Conevski, primarily by the way they use and implement the app architecture, all state management solutions, and of course, the testing itself.
“A great Flutter developer will create and write all the tests for the Flutter apps. Most of the time, a great Flutter developer has tried several different architecture approaches, and they also express their opinion freely about how they would do things. They should also be able to explain why they would do something different and back it up with valid reasons.”
How Proxify helps you find the best Flutter talent
Finding a great developer is not the most uncomplicated challenge in the career world, especially when you ask for no help and do the process alone.
It can be time-consuming and tiring because usually there are many applicants, and most of them will probably be a good fit—but the most significant challenge would be to make a selection that leads to a perfect outcome. Interviews take time to complete, and it is not all just receiving applications and preliminary discussions with the applicants.
The first crucial thing is dedicating a reasonable amount of time to complete the whole process. Also, planning and setting aside needed resources and appointing specific recruiters and talent acquisition specialists is another crucial component.
Additionally, experts will prepare things and take care of onboarding and, if required, training. This process will introduce the candidate to the company and the job obligations.
But imagine how tiring the process would look without help and if it was a one-person task. Quickly selection without much thought will cost significant resources down the road, not to mention repeating the whole interview and hiring process from scratch and losing precious time.
At Proxify, we have excellent talent acquisition specialists and recruiters who pay close attention to every applicant by carefully yet time-efficiently selecting candidates that would continue in the following phases, thus being aware of time limitations. Every single selection process is successful with highlighting the candidates that stand out first thing when the interviewing starts to take place and:
- Preliminary tasks for self-assessment to shortlisted developers
- Scheduled call with the recruiters as a pre-screening phase (to those that submitted a successfully resolved assignment as a first and previous step).
- We focus on technical and non-technical skills, proficiency in the English language, and substantial, good quality expertise and experience of the candidate in the past.
- Assigning a practical task or test that confirms the core skills needed for the job position
- Finalizing with a technical interview led by a Flutter developer
We pay great attention to every candidate's skills and expertise so that a great Flutter developer does not ‘slip through elsewhere’ as a potential new hire. Paying attention to timeframes and carefully checking all submitted tasks and tests guarantee that the best Flutter developer is selected every single time.
In a fast-moving and ambitious career world where agencies take the interview process lightly or irresponsibly toward the company and applicants, we at Proxify make an excellent candidate selection without losing track of time and always welcome the utmost best applicants.
Essentials and assessment of a Flutter developer
The right person to answer questions about Flutter developers is primarily Flutter developers. We asked about personal opinions regarding good assets and skills in a developer that would join a team and the focus during the assessment process, what is good to have regarding technical expertise, and similar.
As in the sections above, in this exact context, Zoran listed the following check-points for discussion and assessing the Flutter developer better:
- Hands-on experience with building Flutter apps
- Naming the most complex thing implemented through Flutter and how the developer implemented it.
- Questions about an app architecture
- State-management solution
- Testing of Flutter apps
He also added:
“To assess a Flutter developer, I would ask most about architecture, Dart programming language, and state management. I clearly understand the skills, mostly with these checkpoints and questions, especially if that developer had experience with larger projects. When discussing such points, I know that developers also have good knowledge for approaches and best practices”.
Benefits of Flutter
Many benefits are associated with Flutter, but it is good to work with it due to the shortened time for writing code and broadening its community of users.
Plus, there is the individual rendering engine with custom widgets for iOS and Android; the platform is also simple to understand and implement. Additionally, you can run Flutter apps in browsers without changing the written code. If there’s a need to create and develop new features, you will reduce the development time from one or a few months to just less than a month.
The UI looks visually gorgeous with widgets that contribute to what you see on the screen. Also, costs are reduced with Flutter because one single team can make the native apps development instead of separate ones for iOS and Android.
What benefits did Flutter developers mention?
The benefits of working with Flutter are numerous, but those that stand out significantly are:
- Quick MVP/prototyping,
- The time for development and how fast this process goes,
- A lot of packages included,
- An open and friendly community of experts
Regarding practical usage, Zoran added,
“We use Flutter for cross-platform mobile app development for iOS and Android. With the recent upgrading in the years, it can now support platforms like Web, Desktop (Mac, Linux, Windows), and such embedded devices. Amazingly, you need just one code base for software building that successfully runs on mobile, desktop, and web”.

Why use Flutter?
Flutter is Google’s open-source software development kit for building brand-driven user interfaces for multiplatform (mobile, desktop, and web) applications. The Flutter SDK includes a framework built with Dart programming language, a C/C++ rendering engine, an out-of-the-box library of Material Design and Cupertino widgets, APIs for integrations, and a set of tools for development, testing, and compiling apps.
How does Flutter work?
A Flutter app consists of widgets. In contrast, to React Native or Xamarin, Flutter doesn’t use any widgets shipped with iOS and Android platforms. Instead, it draws all UI components independently using its own rendering engine and Skia graphics library. The widget code gets compiled to iOs or Android native code ahead of time, which ensures all UI elements look and behave the same on any device or platform version.
What is Flutter used for?
Flutter is used for the development of 2D mobile apps for Android and iOS that run with native performance. In view of its fast development cycle, Flutter became a popular UI toolkit for prototyping and building MVPs with beautiful design.
Who uses Flutter?
Flutter is used by both startups and enterprises. eBay, Square, CapitalOne, Groupon, Baidu, and Alibaba are among the famous brands that have adopted Flutter. Google themselves use it for developing Google Ads and Google Assistant apps.
Is Flutter a good choice?
Flutter is a good choice for building natively compiled apps with brand-driven designs. It allows creating custom UI elements that work well and look good on both iOs and Android platforms. As Flutter’s popularity among developers is growing exponentially, finding a good programmer to build a Flutter app would be quite easy.
Why does Flutter use Dart?
Dart was chosen as a programming language for Flutter’s framework and widgets for three main reasons. First, the language is object-oriented, which is good for user interface programming. Second, it has efficient memory management and allocation. Third, Dart allows using JIT compilation during development to improve developers’ productivity, and AOT compilation in production to ensure fast and predictable app performance.
Is Flutter good for cross-platform development?
Recent updates in Flutter
Ever since announcing Flutter in 2015, the community behind this mainly mobile app development framework has been busy updating, patching and optimizing Flutter. In fact, the Flutter team has recently released an update in February 2022, in which they introduced desktop support for MS Windows and a couple of other novel things. Some of those updates include improvements in performance, smoother animations in iOS, Android multidex support, and more. Additionally, the latest Flutter stable release (2.10) has also introduced some improvements in the web portion of the framework as well. Fixes like proper edge scrolling, removing overhead while importing multiple widgets, and optimizing the link widget should make the Flutter user experience that much better. Also, apps that are built using Flutter will have the leverage of the recent transition to a new color scheme generator called Material 3.
Which apps use Flutter?
Flutter has been used to build many programs and applications. Apps like the experimental social media network KlasterMe, the popular Hamilton musical app, and a New York Times-backed puzzle app called KENKEN are all made with Flutter. Today, Flutter is becoming increasingly popular among developers because of its cross-platform compatibility and the ability to directly host your applications on multiple platforms, including the web.
