Hire Flutter Developers in 48 Hours

Flutter is one of the most popular frameworks among professional developers. it takes 6th place (12.64% of coders use it) and is the most widely used cross-platform tool, according to Stack Overflow Developer Survey 2022. Also, it is the second most wanted framework, with 13.52% of responses.

The technology possesses a lot of features that can make your product stand out. Therefore it is not surprising that companies such as Alibaba, BMW, Google, and eBay chose it to develop their solutions. But should you follow their example?

Why Freelance Flutter Developers Will Benefit Your Business 

Flutter is a full-fledged SDK. It is based on the DART programming language, which in turn is based on the notorious Java. 

It is a technology for creating high-quality intuitive GUIs on various platforms. It can be easily  combined with existing pieces of code and is used by developers around the world. And most importantly, it is open source and completely free. The first version of Flutter was published in 2015.

Below are the main advantages Flutter has over other frameworks.

Serious Approach to UI Consistency

The platform uses its own widgets with advanced animation and gesture recognition. The widgets are rendered using the Skia graphics engine. This engine allows a Flutter developer to draw each element correctly for each version, and as a result, receive UI uniformity in applications.

People prefer user-friendly and attractive products, so in the process of developing your startup, it is important to pay enough attention to the user interface, which will encourage a person to use the application longer and more often.

Shorter Time-to-Market

Like other cross-platform frameworks, Flutter provides faster time-to-market than native solutions as Flutter developers need to build only one codebase. At the same time, it has significant advantages even compared to similar technologies — it offers a faster rendering engine and is based on the Dart language that was created exclusively for cross-platform coding. Together, this makes it possible to significantly speed up production.

One Flutter developer can complete the tasks of two native developers in the same time frame. Thus the software development process takes up to 50% less time.

Platform Flexibility

Freelance Flutter developers can write applications for any major platform today, including Android, iOS, Web browser, Windows, macOS, Linux, and even embedded devices.

Imagine that you need to make an application for two popular operating systems for smartphones at once, and also maintain its web version and, for example, a desktop application for Mac and Windows. 

To build an application separately for each platform, you would most likely have to assemble a team of specialists in at least Swift, Kotlin, JavaScript, and C#. Then you would have to deal with the transfer of design for each platform and maintain and update at least four codebases.

With Flutter, things are much simpler: you hire a team of Flutter devs and build all applications in the framework.

Types of Projects That Will Benefit From Flutter Developers

While Flutter is a rather universal tool, the following project types will see the most advantages of the framework: 

• MVPs. Advantages of Flutter like short time-to-market and plenty of debugging and testing tools help create decent minimum viable products. They allow you to quickly test an idea and launch a startup with minimal cost and time.
• Mobile apps. The cross-platform feature of the technology allows Flutter developers to build full-fledged applications for companies that can be launched for both Android users and iPhone owners.
• Progressive web apps. Thanks to a single code base and efficient performance, your website can be put on a user’s device. 
• Single-page applications. Flutter developers can build functional SPAs that are characterized by fast loading speed. All this is done with the help of an internal graphics engine and ready-to-use widgets.
• Scaling a mobile app into a web and desktop project. With this SDK, your users will be able to leverage the app on any platform including desktop devices. Your product will be flexible and consequently will target a wider audience.

These are the most common product types. But if you can’t find yours it is advisable to turn to experienced consultants.

The bigger the tech stack of your Flutter developer, the less boilerplate code and shorter time-to-market you get.

Experience of Flutter App Developers

Junior Flutter Developer

A Flutter developer of the lowest seniority level (0-2 years) should have the following experience:

• Ability to work with Figma or Sketch
• Basic knowledge of native platforms
• Experience in developing client-server applications
• Experience with version control systems (Git)
• Knowledge of Android SDK/iOS SDK
• At least basic knowledge of Dart and Flutter
• Knowledge of Kotlin/Swift (optional)
• Knowledge of mobile app design principles
• Knowledge of the Bloc architectural pattern and experience with it
• Understanding how Bluetooth works, experience with Bluetooth in Android
• Understanding of OOP principles

A junior developer can solve small, simple, and well-defined tasks.

Middle Flutter Developer

A middle Flutter developer has 2+ years of experience and already knows quite a lot, including the following:

• Understanding HTTP, REST, JSON, WebSocket, SignalR
• Knowledge of Cupertino/Material guidelines
• Knowledge of algorithms and data structures

A senior Flutter developer is able to keep the largest and most complex tasks in mind and take into account the most non-obvious interactions and consequences.

How to Hire Flutter App Developers

Finding out what a decent Flutter developer should do is only half of the deal. Then to find the perfect candidate, you have to define the specifics of your project and your needs.

Define Project Needs

Here is how to find out the product’s core specs:

By assessing all these factors, you’ll have a clearer vision of what exactly you will need your Flutter developer to do.

Draft a Job Description

First of all, your job description should match the above needs. Second, make sure to include as much detail as possible: 

• Specific responsibilities — whether it will be building widgets or creating cross-platform apps.
• Employment length — specify if it will be a constant position or project work.
• Experience — indicate if you require the candidate to have a background in a certain language or technology.
• Salary — provide the rates that are acceptable for the company.  

The possible responsibilities your job post could include are:

• Dart programming
• Asynchronous code and networking
• Knowledge of popular libraries and development techniques in the Dart language
• Working with application theme animations
• Development of cross-platform applications
• Unit and Application Integration Testing
• Compliance with architectural patterns

Don’t forget to add industry-related features to the description.

Prepare Interview Questions

The final stage of hiring a Flutter developer is interviewing. When preparing questions, try to focus on the specifics of your project while not forgetting to test the basics. Common questions to ask include:

• What do you think are the benefits of using Flutter for your projects?
• What types of plugins have you integrated into your past projects? Why?
• How do you implement Flutter build modes during development?
• Describe your approach to reducing code execution time.
• What steps do you take to ensure functionality and optimization before a product is released?

Also, you can prepare up to three test tasks. As a rule, written code says more about a candidate than their answers at the interview.

Salary Rates of Flutter Developers

According to glassdoor.com, the median annual rate of a Flutter developer is $130,000. Junior Flutter programmers earn around $95k, while the salary of a middle/senior engineer can extend up to $166,000 per year. Flutter developers can be paid on a monthly or hourly basis. 

While it isn’t that cheap to hire a Flutter developer, the invested costs will have a higher ROI compared to other solutions. The shorter time to market, support from Google, and unique platform flexibility can make all the difference for your product.
