Everything a Client needs to know about hiring Flutter Developers

Complete guide on how to hire flutter app developers

Flutter is an SDK (Software Development Kit) released by Google to help developers to build visually appealing applications for mobile, web, desktop, and embedded devices from a single codebase. According to Google trends, Flutter has more popularity than its major rivals, React Native and Xamarin. This gives the entrepreneurs more reason to search and hire remote Flutter developers that suits their business requirements.

Due to the rising popularity of Flutter, many entrepreneurs now want to build their cross-platform apps using Flutter. As a result, there has been a rise in the number of businesses looking for a quality guide on how to hire remote Flutter developers. Through this write-up, our aim is to help entrepreneurs hire Flutter experts and help entrepreneurs build a quality Flutter app.

Concerns of clients regarding Flutter

Flutter is indeed a powerful platform to develop apps for both mobiles as well as the web. This does not mean that there are no concerns of clients regarding Flutter for their mobile application development. It does not mean that Flutter is ineffective.

It just means that before you choose Flutter, you must fully understand Flutter’s limitations to avoid putting your project in jeopardy.

Few third-party Packages

As Flutter is a relatively new technology the app development process must be thoroughly followed, and the number of third-party libraries and widgets is small. Moreover, there are some widgets in Flutter that are available to only one platform.

Requirement of Dart for Development

Dart is an object-oriented programming language, and once the Flutter coders get the hang of it, Dart proves to be a charm to work with. The problem is that Dart is still new and is not as commonly accepted as a programming language as some other languages like Java, JavaScript, or C#. There are fewer app developers who are proficient with Dart, and this leads to a scarcity of Flutter developers.

Few Digital Platforms

Flutter has excellent support for tvOS, Android Auto, CarPlay, and watchOS. Unfortunately, this excellent support of Flutter is not extended to wearOS/Android Wear. Skilled Flutter app developers need to use native code to solve this limitation.

Large App Size

Small app sizes are preferable as the users have limited storage. This is why top mobile app developers ensure that the app size is kept minimal while developing an Application. Flutter has a minimum app size of over 4MB, which is bigger as compared to the minimum size of Kotlin (550KB) and Java apps (539KB).

This is because Flutter has built-in widgets instead of platform widgets. Although, to be fair to Flutter, its nearest competitors like Xamarin and React Native share the same issue. While Xamarin’s minimum app size is 16MB, that of React native is 7MB.

Most of the issues related to Flutter stem from the fact that it is still new in the mobile app development arena. With Google backing it, Flutter will soon sort out these issues and take the lead in the app development world.

Why Flutter is good for app development?

Why flutter is best for mobile app development?

Within a few years of its launch, Flutter has gained immense popularity amongst the app developer community as a reliable app development technology. There are multiple benefits of Flutter app development that have contributed to the growing prominence of Flutter in the developer community.

Fast Time to Market

One of the major reasons for Flutter’s popularity is that it multiplies the productivity of the hired Flutter app developers many times. With Flutter, experienced Flutter app developers can make instant changes in coding without halting the development process of the application.

The hot reload function of Flutter allows the best Flutter programmers to instantly see the effect of their changes without wasting time in compiling the code. The hot reload function thus plays an important role in speeding up the mobile application development process, reducing the time to market of a Flutter app.

Great Design Experience

Flutter allows app designers and developers to build exquisitely designed apps using the material UI components of Flutter. Flutter gives creative mobile app designers access to a rich library of widgets, using which they can design beautiful apps quickly.

Moreover, Flutter also allows developers the flexibility to create their own widgets. Through customized widgets, remote flutter developers can deploy precise and satisfying user experiences.

Cost-effective Development

If you want to build a native app and want to publish it on iOS as well as Android platforms, then you will need to build two separate native apps. The cost of developing two separate native apps will be double as you will have to employ two separate teams to develop two native apps.

With Flutter, the cost of developing two respective native apps for iOS and Android is reduced to half as a Flutter app will work smoothly on both iOS as well as android platforms.

Efficient MVP Development

Flutter proves to be a great voice for building an MVP (Minimum Viable Product). For startups, building an MVP is a critical part of their startup journey as the MVP helps them to test their ideas in a fast and cost-effective manner. Here are some aspects of Flutter that make it perfect for MVP development.

  • The learning curve is not steep with Flutter.
  • MVP development with Flutter is fast as less coding is required with Flutter.
  • Due to a single codebase, MVP development with Flutter is cost-effective.

Single Codebase

The expert Flutter app developers can build apps for iOS, Android, and the web with minimal edits in the code. The ability of Flutter to allow remote developers to build apps using a single codebase helps the sophisticated Flutter app developers deliver the apps faster.

A single codebase also helps to reduce the cost of developing a Flutter app, as proficient Flutter app developers can go for cross-platform app development and build a cross-platform app that will work on both iOS and Android devices instead of building two respective native apps.

The same codebase for different platforms helps professional Flutter app developers release app updates simultaneously. With two separate native apps, it is hard to release updates simultaneously on different platforms without a proper native app development process. It becomes all the more problematic when the developers are required to make changes in the backend infrastructure to update the app.

How to hire remote Flutter developers best suited for your project?

how to hire remote flutter developers?

When you Google about hiring remote Flutter developers, you will find hundreds of options. A large number of options will leave you confused when you go out to search and hire Flutter developers. We have mentioned a few steps that can aid you in your journey of selecting world-class Flutter developers for your project on your own.

Define a clear scope of Work

It is critical to have a clear scope of work before you approach hiring Flutter developers. The scope of work should clearly state your business goals and the needs of your business. When you prepare the scope of work, you should start by answering some simple questions like

  • What is the exact requirement of the business?
  • What could be the best potential solution for this need?

By answering these simple questions, you will be able to prepare a clear roadmap for solving a particular problem and identify your overall business goals.

You must understand that the remote Flutter developers you hire are experts in programming, but they do not know much about your business. Hence you will have to define a clear scope for them to understand your needs correctly.

You need to share detailed and specific requirements with your hired Flutter app developers and not vague requirements like “introduce something new in our app” or ”build an app that our customers would simply love to use”.

Analyze the Expertise

Once you have written a clear scope of work, you can start shortlisting vendors to hire talented Flutter app developers. The first factor that you should look at before you find Flutter app developers to hire is technical expertise. Here are a few factors that will help you gauge the technical proficiency of the Flutter app developers that you want to hire.

A good way to assess the technical skills of the Flutter app developers would be to check their contributions on platforms such as GitHub and Stack Overflow. When you assess the participation of the skilled Flutter app developers on these platforms, you will find out how good the developers are in providing coding solutions.

If your business has a technical person, then you should consider conducting a coding assessment before you hire Flutter app developers. A coding test will help you hire the right talent. Here are some testing tools that will help you conduct a coding test:

  • Interview
  • Devskiller
  • HireVue
  • CodeSubmit
  • HackerRank

Check previous Projects and Market Reputation

Would you put your Flutter project in jeopardy by choosing to work with an incompetent Flutter app developer? To ensure that you select the most appropriate partner for your cross-platform app development project using Flutter, it is essential that you research the market reputation of the selected Flutter app developers before you hire them.

There are many websites such as Clutch, TopDevelopers.co, and Extract.co that would help you determine the reputation of the company by checking their previous work and client reviews.

Another way to check the reputation of the Flutter developers would be to talk with their past clients and ask the clients about their work experience.

The idea behind conducting so much research before selection is to select appropriate Flutter app developers who have a reputation for delivering high-quality Flutter apps within the stipulated deadline.

Clear Communication regarding Budget

Do you love sudden spikes in development costs? No, then clearly communicate the budget of your Flutter app development project to your hired Flutter app developers. Before you approach the most appropriate Flutter app developers, you must figure out how much money you are willing to invest in your project.

Once the budget is prepared, then discuss the budget with your Flutter app development partner to ensure that your budget estimates are correct.

Protect your Data and Intellectual Property

Privacy and data security are the two biggest concerns for businesses that want to outsource their Flutter app development projects. The concerns are especially big when you consider hiring offshore Flutter app developers as the intellectual property laws differ from country to country.

You will share sensitive information with your outsourcing partner while working on the project. To protect your intellectual property, ensure that you sign a Non-Disclosure Agreement (NDA) with the outsourcing Flutter app development partner before you assign the project.

Apart from signing the NDA, you should also check whether your hired Flutter app developers regularly conduct security audits to protect the data or not.

Choose a flexible Partner

Flutter app development is a complex process, and many times you will need to add certain features mid-way through the project. You should hire a company that caters top-quality mobile app development services and will be flexible enough to cater to any urgent requirement whenever the need arises as your tech partner or sign up for the maintenance contract.

Thus, the flexibility of the Flutter development partner becomes an important factor to consider while outsourcing your Flutter app development project. It is a good idea to include flexibility terms in the agreement before you assign the work.

How much does it cost to hire remote Flutter app developers?
