Why Flutter app development is the most preferred choice for startups?

There is nothing better for a young business than having mobile applications perform on various platforms like native apps. After deciding to launch mobile app development, the next pending crucial step will be choosing the best-suiting frameworks and tech stack. 

What is the Flutter app in a nutshell?

Exist many available frameworks you can choose from. The budget-friendly and straightforward solution for startups is a cross-platform app development with Flutter, allowing you to reach your target audience through different platforms. Flutter mobile app development framework has transformed the whole digital world allowing developers to approach app development from a different angle. 

Flutter framework is an open-source UI elements software development kit created by Google. This framework for building cross-platform apps uses a single codebase, allowing developers to access a hybrid mobile app development world, where they can create apps on both Android and iOS with just one code. Flutter offers the ability to create cross-platform applications just like it was a native app development.

Interesting fact: Flutter framework occupies 2nd place in the rank of the leading tools for cross-platform app development by Google.

Flutter for Startups

But before diving deeper into the opportunities Flutter provides for app development let us look through some statistics.

According to Statista insights, Flutter is the most popular cross-platform mobile framework used by global developers, according to a 2021 developer survey. Based on the survey, 42 percent of software developers used Flutter to build their mobile apps. 

Statistics on Flutter

Flutter apps popularity left behind even the most popular frameworks, such as Xamarin, Ionic, Unity, and Phone Gap, and even approaches the React Native position.

Reasons why startups should consider Flutter app development?

Startups should take into account the next aspects when considering what framework to choose for app development:

  • Customer demands for fast and efficient solutions are growing together with the need for cross-platform and backend development.
  • To stay afloat and be better than the other competitors, startups should develop apps both for Android and iOS devices.
  • They should focus on the user interface, its design, and its usability. Intuitive, interactive and user-friendly app increases the number of downloads.
  • Plan the future scaling of mobile apps from the preliminary stages. It saves development costs and time.

Flutter app development ensures that the app is consistent across multiple devices and has a beautiful design thanks to rich Visual Studio Code equipped with unique designs. Here are some reasons why building apps with Flutter is the best choice for startups:

Flutter app development enables to save the development costs

Money is one of the key aspects to focus on both for startups and large enterprises. The longer the app development process takes, the more costly it would be. Flutter’s Hot Reload feature allows developers to instantly introduce changes in the backend and eliminate the requirement of recompilation decreasing the development time. Thus, thanks to Hot Reload developers can make changes in real-time and see the results instantly. Moreover, Flutter increases the productivity of the development team by 10!

Unique app UI design and user experience

Unique Android and iOS power-packed widgets allow the creation of a unique interactive experience. A broad choice of cross-platform tools enables developers to create amazing designs with minimal effort and impress target users.

One codebase that will run smoothly on multiple platforms

One codebase allows releasing Flutter apps on different platforms with no need to hire different developers, unlike any other languages. It is a cost-effective tool for cross-platform app development allowing to build the app of uncompromising quality even for older devices. App performance will impress both users accessing the app from iOS platforms and Android devices.

Make your app infrastructure serverless, redundant, and scalable

Flutter is integrated with Google’s Firebase providing such services, as cloud storage, hosting, real-time databases, etc. Combined with other tools, Firebase allows developers to automate the app development process, make it easier and quicker and create a scalable product, unlike any other technology.

Launch MVP with limited resources, budget, and time

Flutter allows the development team to build apps without any hassle. Moreover, the opportunity to introduce changes in real-time allows for shortening the mobile development process. The impressive toolkit enables the owner to launch the Flutter apps with unique designs and features even within a limited budget. It allows quick MVP development and instant release even with limited resources!

Ability to reuse the app codes

Flutter app development allows speeding up the development process and decreases testing. It is possible due to the opportunity to translate codes into different languages so that once written codes can be used with different plugins by Flutter developers. A single QA session is enough to test all features, functions, and programs.

reasons to invest in Flutter

Why developing a cross-platform app with Flutter is beneficial?

Flutter is a free and open-source framework allowing to save costs on license and access to the development tools.

  • A complete software development kit (Flutter SDK) provides all the necessary resources to build high-performance, intuitive apps for all operating systems within one codebase. It is based on the Dart programming language and Dart programs can be run directly.
  • Rich technical architecture, comprising everything you may require for app development. International libraries allow localizing apps.
  • Flutter app development allows using IDE-guided setup for both Android and iOS, simplifying the configuration of the environment.
  • Rich of components supports various API integrations and support UI rendering components.
  • Advanced tech support for testing apps, ready-made widgets, and unique features. It allows to easily manage and fix bugs.
  • Continuous maintenance including tech and documentation support.
  • It makes the app easily scalable in the future, in case of such necessity. You do not need to spend additional time and money or build a new app from scratch.
  • Understandable documentation Flutter provides to the users makes it easy to learn, and a wide community and continuous support with tutorials make it accessible for developers of any level.

How much does it cost to develop an app with Flutter?

After you have finally decided to opt for Flutter development, arises the following question – how much does it cost to develop an app like Flutter? Exists a number of cost-related factors that influence the overall budget spent on the app development. App complexity, number of features and integrations implemented, choice of platforms, and included functions will comprise and formulate the total amount of money spent on app development.

As a startup, you do not need to invest huge sums of money into a fancy, fully-featured app. Initially, it will be better to build an app with flutter for a single platform and, as your business will grow, scale it up expanding the functionality and adding new features.

Moreover, Flutter development is the best solution for startups, since you will get the support of a wide community of experts. They will share their knowledge about Flutter’s own widgets and plugins that help you in upgrading your iOS and Android app with the latest features.

Concerning the app development cost with Flutter, the Flutter project budget starts with 50K monthly and may take minimally 3-4 months. Take into account that fast Flutter application development speed allows for shortening the duration of the project, thus lowering the development costs.

Top companies who successfully used Flutter for cross-platform app development

The best proof demonstrating that flutter is the right development choice is the list of companies, which have successfully used this technology to refine their designs and create new products. 

One of the crucial benefits of Flutter and its programming language is that it allows building an app that looks and functions like a native one. This hybrid mobile app development technology has become the choice of many developers and software vendors and suits both for building new products and upgrading the existing ones.

Here are the apps built with Flutter, then demonstrate its versatility and explain the popularity of the current framework.
