How to Interview and Hire Flutter Developers
Flutter and React Native are well-known for their power to undertake mobile app cross-platform development. Flutter is relatively new, however, this portable UI toolkit has gained considerable popularity in a very short space of time.
Since the launch of this open-source framework in 2018, the many advantages of Flutter has seen an increasing number of developers use it.
You can use Flutter for app development if you have the goal of creating an application that works on multiple OS platforms. The main platforms include Android, iOS, web, Linux, macOS, and Fuchsia. This is because, using Flutter, one codebase enables you to run mobile, web, and desktop apps, negating the need to create more than one codebase.
Flutter offers a near-native user experience thanks to its UI components library and widgets. Flutter apps consume less memory and storage capacity, therefore, they are lightweight. This framework offers excellent performance.
Flutter offers automation capabilities that help with app development and release processes. This framework offers comprehensive testing support, which expedites app development projects.
Flutter is easy to learn. Flutter developers can access extensive documentation. A growing and vibrant community of Flutter developers is another advantage. We can expect significant ongoing enhancements to Flutter too.
Many organizations find mobile development using Flutter an attractive option due to the above-mentioned advantages. Flutter app developers are in demand, therefore, you might find it hard to hire Flutter developers quickly.
The good news is that hiring Flutter developers can become easier if you take the right approach. You might think of hiring Flutter programmers from a freelance platform. However, hiring Flutter experts from a trusted Flutter app development company like DevTeam.Space is a far more reliable choice. We will get to this later on.

I. Good communication and team skills
The best Flutter developers must have excellent “soft skills”. These are as follows:
- Communication skills:
Communication is one of the keys to successful Flutter development projects. Your Flutter developer should communicate effectively with all relevant stakeholders and not only peers.
You need Flutter programmers to work effectively in a team environment. They should work collaboratively with your existing team too.
- Passion for excellence:
Smart Flutter developers should value quality. A laser-like focus on quality helps them to deliver the right user experience.
You need Flutter developers to meet the project deadlines. They should also meet the project cost and quality requirements.
Flutter consultants and developers should understand the requirements from the perspective of the end users. They need empathy for this.
How to find the best Flutter experts?
You now understand the relevant skills that your Flutter developers need, therefore, you can start to hire developers. Take the following steps:
1. Decide the kind of platform to hire Flutter app developers
You have a great business idea, therefore, you plan to develop an app. You are trying to build a dream team for this project. Your success depends on hiring the right people. Which kind of hiring platform should you use to hire competent developers?
You might find it tempting to hire freelance Flutter developers. After all, you might be able to hire a freelance Flutter developer at a low hourly rate. Will this help you to develop complex Flutter apps?
The reality is that Freelancers might work only a few hours a day on your project. They have several projects going on simultaneously as they need a steady income stream. You might find it hard to manage the work of part-time developers. Hiring remote Flutter developers on a freelance platform might compound this problem.
Freelance platforms don’t offer any project management support. Freelance developers routinely look for better earning opportunities so they might leave your project mid-way. You will need to find replacement developers in this case.
Such uncertainties can adversely impact your mobile or web development projects. The impact is more pronounced for complex projects. For complex projects, you should hire full-time developers from trustworthy software development companies like DevTeam.Space which offer expert Flutter development services.
DevTeam.Space offers highly skilled, experienced, and motivated Flutter developers for you to outsource. They work full-time on your project as they work exclusively for our platform. We offer both complete development teams and individual developers for outsourcing.
Our software development processes are data-driven, and they are designed to help you to manage your project as efficiently as possible. We understand the sensitive nature of your data. We sign an NDA and ensure that your intellectual property is safe at all times.
2. Interview the shortlisted candidates
You have decided on the hiring platform. Subsequently, you posted your Flutter developer requirements. You will now need to interview developers as their applications come in.
You can undertake the interviews if you have the required skills. Alternatively, you can ask other project managers, colleagues, or friends to help you if you don’t. Get in contact with us if you need help but can’t find it. Use Flutter interview questions that are available online if you need them.
Cover all the key technical areas during the technical interview. Go beyond theoretical questions and assess the hands-on experience of your candidate developers.
Check how the candidates have developed creative solutions in their past projects. Describe your business requirements and ask for solutions. Look for clearly stated solutions and not vague answers.
3. Provide detailed information about your application development project
You have selected and hired Flutter developers, and you now need to onboard them. The onboarding process is a key requirement to build mobile apps successfully.
Explain your project requirements to your new developers. Provide them with the relevant project development documents. You should share the project specifications and technical solutions with your developers.
Provide access to the project’s technical environment and tools. Developers need access to the code repository.
Introduce the new developers to your existing team. Explain their roles and responsibilities.
Describe the project plan and schedule to your new developers. Explain the project milestones. Set up a clear communication channel and establish accountability.
Interview tips to hire Flutter developers
We offer the following suggestions when hiring Flutter developers:
A. Pay attention to the experience level of the team when you a hire Flutter developer
Flutter enables you to achieve a lot. It’s a user-friendly framework with powerful capabilities. This fact might prompt you to hire inexperienced developers. However, if you do, you expose your project to risks.
Developing a Flutter app can be a complex project. Hire enough senior and mid-level developers only. That will result in a judicious mix of experienced and junior developers. To hire senior developers, contact a reliable software development company like DevTeam.Space. We provide expert Flutter app development services that include outsourcing our field expert developers and dev teams.
B. Look for developers with experience in developing apps that run on multiple operating systems
Developers that have created apps targeting multiple platforms are likely to have more experience with Flutter. They have experienced many different aspects of Flutter development. This helps them to create better Windows apps, web apps, Android apps, etc. You want that kind of experience in your team. Hire candidates that have already developed apps that run on multiple platforms before.
C. Look for the knowledge of coding best practices
While the Flutter framework is powerful, you want to make sure that you get the best of it. Developers with in-depth knowledge of code best practices will get the best out of Flutter. Hire Flutter developers that understand coding guidelines well.
D. Hire developers from flexible service providers
You need a software app development partner with flexible hiring models for your Flutter app development project. A fixed-price model suits a simple app development project with basic specifications.
You will likely require a flexible times-and-materials model for app development with variable feature requirements. Such a model helps you spend resources, in terms of time and money, according to your project requirements.
You should evaluate the services of any software app development company in detail and not just go by the words of their sales team. Analyze the company’s past projects. Talk with their past clients and to get feedback about their experience working with the software app development company.
Examples of coding questions to ask during the interview when hiring Flutter developers
You should ask questions that help you assess the relevant skills and experience of developers. The following are a few examples:
A. Explain the concept of the “widget” in Flutter. How does Flutter utilize the widget tree to build user interfaces?
In Flutter, a widget is a lightweight, immutable description of part of a user interface. Everything in Flutter, from a simple button to complex layouts, is a widget. Widgets are arranged in a tree structure known as the “widget tree.” The widget tree represents the hierarchical structure of the UI.
When a widget’s properties change or the UI needs to be updated, Flutter performs a process called “reconciliation.” During reconciliation, Flutter compares the current widget tree with the new one and updates only the parts that have changed. This approach is efficient because it avoids rebuilding the entire UI and minimizes performance overhead.
B. What are “StatelessWidgets” and “StatefulWidgets” in Flutter? When would you use one over the other, and how do they handle UI updates?
In Flutter, “StatelessWidget” and “StatefulWidget” are base classes for creating UI components. “StatelessWidget” is used for components that don’t need to manage the internal state. They receive their configuration through constructor arguments and don’t change over time. “StatefulWidget,” on the other hand, is used for components that need to manage internal state.
They have two separate classes: one for the widget itself and another for the mutable state. When the state changes, the widget tree is rebuilt, and the “build” method is called to reflect the updated state visually. Choose “StatelessWidget” when the UI is purely based on input data, and use “StatefulWidget” when the UI needs to react to changes in the internal state.
C. Explain the concept of “Hot Reload” and “Hot Restart” in Flutter. How do these features aid in the development and debugging process?
“Hot Reload” and “Hot Restart” are essential features in Flutter that streamline the development and debugging process. “Hot Reload” allows developers to instantly see the changes they make to the code reflected in the running app. It maintains the app’s current state, which is particularly useful for tweaking the UI and quickly iterating on design changes.
However, “Hot Reload” doesn’t reset the internal state, so it’s great for UI changes but may not work well if there are structural code changes. “Hot Restart” fully restarts the app while maintaining the state of the debugger. It’s used when you want to reset the app’s entire state, including the internal state. These features significantly reduce development time and help developers see the effects of their changes without losing the app’s context.
Submit a Project With Zero Risk

Flutter developers and consultants need to know Dart, therefore, you should look for Dart skills. Dart skill requirements don’t impose a heavy burden on Flutter developers though. The Dart programming language is quite like C#, and many developers already know C#.
A Developer with native app development experience or a full-stack developer stands a better chance to become a successful Flutter engineer. Flutter uses many concepts of native iOS and Android development. We recommend you hire a Flutter developer with native development experience to facilitate mobile application development.
