Essential Flutter Developer Skills to Assess while Hiring for Your Next Project  

Sagar Bagsariya,

Companies that want to develop multiple apps with high performance and consistent yet elegant UI/UX design in a limited time choose Flutter, a cross-platform app development framework.

Flutter offers extensive platform support, customizable widgets, and a UI framework coupled with an object-oriented programming language Dart and Google support. It wasn’t hard to foresee that Flutter development would soon become the talk of the software development town.

But what has become challenging is hiring Flutter developers with the right skill set.

With the high demand for hiring Flutter developers, the chance of hiring amateur developers increases. It happens majorly for two reasons: 

1) You don’t know how to hire Flutter developers

2) You don’t have time for a lengthy recruitment process.

To help you avoid any worst-case scenario, we have created this guide with a checklist of skills required for Flutter developers. So, get ready to understand Flutter developer skills and how to assess their expertise.

Basic Skills Required for Flutter Developers

In the fast-paced realm of Flutter app development, the foundation for success lies in possessing specific indispensable basic skills. In other words, by keeping an eye on the below fundamental attributes, you can separate the ordinary from the extraordinary.

  1. Proficiency in Dart Programming Language

Dart is the beating heart of Flutter, and a skilled developer should be well-versed in harnessing its capabilities to create efficient, clean, and maintainable code.

So, when interviewing candidates, inquire about their experience with Dart and its unique features, such as strong typing and just-in-time (JIT) compilation. An exceptional developer might share how Dart’s simplicity and readability allowed them to craft elegant solutions to complex problems in previous projects.

  1. Understanding of Flutter Framework Fundamentals

Your ideal candidate should be intimately familiar with Flutter’s core concepts, such as widgets, layouts, and animations.

During the evaluation process, delve into the candidate’s knowledge of Flutter widgets and their application in crafting captivating user interfaces. Encourage them to discuss their experience with stateful and stateless widgets, as well as how they’ve managed widget lifecycles to optimize app performance.

  1. Knowledge of Mobile App Development Concepts

Look for candidates who can seamlessly navigate the intricate landscape of app architecture, navigation patterns, and data management.

As you engage potential Flutter app developers, inquire about their expertise in app design patterns like Model-View-Controller (MVC) or Provider pattern. Listen for anecdotes on how they tackled real-world app development challenges, such as handling user authentication or integrating third-party APIs.

  1. Familiarity with Version Control (e.g., Git)

In the collaborative world of software development, version control is the compass that ensures smooth navigation through iterations and updates. 

To assess a candidate’s proficiency in this area, inquire about their experience with Git workflows, pull requests, and branching strategies. An impressive developer might share how Git facilitated collaboration in past projects, allowing multiple team members to contribute harmoniously to the codebase.

Look for these Technical Skills in Flutter Developers

When it comes to technical prowess, a stellar Flutter app developer should possess the following skills:

  1. Widget libraries and UI/UX design
  • Experience with Flutter’s built-in widgets:  Check for proficiency in using Flutter’s widgets to create appealing interfaces.
  • Custom widget creation and theming: Ask developers if they can design unique widgets and maintain consistent theming.
  • Responsive design principles: Assess knowledge of adapting apps seamlessly to various screen sizes and orientations.
  1. State management
  • Understanding of various state management approaches (e.g., Provider, Bloc, Redux): Evaluate their comprehension of different state management patterns and their ability to explain when and why they would choose a particular approach 
  • Implementation of state management in real-world projects: Look for evidence of their successful implementation of state management in past projects.
  1.  API integration and data handling
  • Experience with RESTful APIs and HTTP requests: Inquire about their API usage and efficient data retrieval.
  • JSON serialization and deserialization:  Assess Flutter developers’ ability to convert data between JSON and Dart objects.
  • Caching and handling data efficiently: Ask about their strategies to optimize data handling and app responsiveness.
  1. Testing and debugging

Unit and widget testing in Flutter: Inquire about their testing practices and how they ensure code reliability.

Debugging techniques and tools: Evaluate potential Flutter developers’ problem-solving skills and familiarity with debugging tools.

  1. Performance optimization

Identifying performance bottlenecks: Inquire about their experience in identifying and diagnosing performance bottlenecks that could impact app speed.

Techniques to improve app performance: Ask for concrete examples of how they’ve improved app speed and responsiveness through optimization strategies.

Flutter Developers’ Skills Assessment Based on Experience & Portfolio

You cannot hire Flutter developers without reviewing their experience and portfolio. Assessing their abilities and potential to bring your app vision to life is key. Let’s find out how to carry out this analysis carefully. 

  1. Years of Flutter development experience: Start by looking for developers with a substantial track record in Flutter development. Then, dive into their experience in various app genres and complexities, as this showcases their adaptability and problem-solving skills.
  1. Previous mobile app projects: Check out their portfolio and the apps published on app stores. Don’t forget to analyze what reviews and ratings these apps have received. This will help you gauge app performance and user satisfaction, thereby developers’ skills to create user-friendly apps. 

While assessing Flutter developers’ experience and work, analyze their ability to handle projects of varying scopes and requirements. You can do this by taking notes on the types and complexity levels of the apps they’ve built.

II. Inadequate Experience with State Management and API Integration

There are state management approaches Flutter developers should be familiar with, such as Provider, Bloc, or Redux, and if they are not, it’s a red flag. Also, analyze their experience in integrating and handling data from RESTful APIs.

III. Limited Understanding of UI/UX Design Principles

If you don’t want your users to abandon the app after the first use, pay close attention to this. It’s a red flag when Flutter developers demonstrate poor demonstration of creating visually appealing and user-friendly interfaces in their portfolio. 

Because they will be unable to articulate UI/UX design decisions and customize the widgets, leading your app to look dull. 

IV. Poor Communication or Teamwork Skills

While having a skills assessment, pay attention to developers’ communication skills as well. Are they explaining technical concepts clearly? Is there any sign implying collaboration challenges? You will need to read between the lines to assess if they are good at communication and teamwork. 

Even if you are outsourcing, paying attention to these red flags will ensure the right selection of Flutter developers.
