What is the primary prerequisite of success in any business? For any firm, be it a full-fledged company or a startup, it is vital to expand its audience and reach out to a maximum number of people. And what is the channel of rapport with consumers that is sure to propel your enterprise in this direction? In the high-tech world of the early third millennium, the way to a client’s heart is through their smartphone. 

Being aware of this simple truth, entrepreneurs shape their marketing strategies with a heavy reliance on digital tools that the IT industry offers. One such tool is mobile apps that serve as an ultimate means of winning new leads and retaining loyal customers. Naturally, the revenues they generate are on a steady growing pattern – the only tendency to intensify within the foreseeable future.

However convenient and universal this marketing instrument may be, it has some development limitations that significantly hamstring the triumphant progress of native apps. The basic of these constraints is the persisting division within the software realm that forces business owners to make a choice between Android- and iOS-powered devices while commissioning their app to developers.  

Either option has its merits and demerits. Whereas Apple owners typically hail from well-to-do countries and social strata having more money to spend, Android gadget users still prevail in quantity so they can make up for their lower purchase potential by sheer numbers.  

Flutter app development | Consumer spending

A possible solution to this dilemma might be developing two apps to fit both operating systems. It looks like a perfect way out until you consider the financial side of the venture. Building one native app is quite expensive (especially for budding entrepreneurs), while splurging on two spells unsustainable expenditure even for many middle-size companies. In this predicament, specialists of Diceus recommend considering cross-platform, where both in terms of quality and cost Flutter development reigns supreme.

Flutter app development: A choice full of promises 

Being not yet of “school age” (in fact, it was inaugurated just five years ago) Flutter framework has outgrown its infancy as an Android-building tool and has gradually matured into a cross-platform toolkit. Using one codebase of Flutter, the developers can create apps for a range of operating systems, including (besides Android) iOS, Linux, Windows, and some lesser ones. 

The system of this brainchild of Google encompasses two components – the SDK (Software Development Kit) and the framework. The former contains a set of tools to be employed for app building, among which those that are used to translate the Flutter code into the native one deserve a special mentioning. The latter is a library with a wide array of widgets (sliders, buttons, text inputs, etc.) to be utilized for UI creation. They define stylistic (colors, fonts), layout (padding), structural (buttons, menus), and other elements of the app’s UI. The widget set is in no way a closed roster since developers can add their own ones if they feel that something is lacking. 

Any framework is written in some programming language, and for Flutter, it is Dart. Being related to Java, it is quite easy to master if the developer has a preliminary proficiency in Java or C++. Dart is universally recognized to be one of Flutter’s fortes. It is so not only because its object-oriented structure is perfect for front-end development.  

Dart’s unique characteristic is utilizing AOT (Ahead-Of-Time) techniques to compile immediately into the native code of the platform, making a JavaScript bridge employed by other frameworks superfluous. As a result, the access to native widgets is affected in the twinkling of an eye, which reduces the launch time of the app tremendously. The list of bonuses that come in Dart’s wake also includes: 

  • generational garbage collection 
  • renewal of the view tree for every new frame 
  • the availability of specialized debugging tools (Dart Observatory and Dart Analyzer) 
  • the existence of a “tree shaking” compiler 

Flutter benefits: A user’s and a developer’s perspective 

What makes Flutter apps a top product as far as UX is concerned?  

  • High performance. On Flutter-friendly devices, the rendering speed is breathtaking 120 frames per second. If your gadget doesn’t support Flutter, the performance is twice as less, but it is still a pretty solid index.  
  • Universal UI. Whatever the year of release or type of the operating system your device runs on might be, UI will look identical on all of them. 
  • Rich adaptivity. By leveraging third-party ports with their plugins, mouse and keyboard functions, and APIs, Flutter apps can be made (with a little tweaking) to run on any device with a screen (even a desktop or TV!). 
  • Negligible compatibility risks. Thanks to direct compilation into the native code practiced by Dart and an impressive roster of widgets, Flutter apps keep potential compatibility problems to a minimum. 
  • Inclusiveness. Flutter apps can be fine-tuned to be used by people with disabilities as well as by speakers of 24 languages with various cultural backgrounds. Font size adjustment, screen contrast intensification, spoken feedback on UI features, currency and measurement unit choice, date presentation, and many other internationalization and accessibility settings make a Flutter app extremely user-friendly.  

Having considerable experience in mobile app building, experts of Diceus see plenty of reasons why Flutter app development is infinitely worthwhile. The chief ones among them are as follows: 

  • A high speed of development. On average, two or three months is enough to build a Flutter app. Such an outstanding time-to-market indicator is possible due to two features of the toolkit. 

The first is its magic hot reload button. By pressing it, you bring to the screen all code alterations you have introduced before. Since the code is updated automatically, you don’t have to restart the app but can proceed with coding while the app is running. Bugs and errors are disposed of in the same way. 

The second is the widget library. It’s not only the size of it (which is quite voluminous!) but also the mode of arrangement. Their tree structures make swift development a breeze (and a swift breeze, too). 

  • Inherent testing opportunities. Flutter SDK contains tools to execute widget, unit, and integration tests without resorting to third-party testing software. 
  • Easy learning. Dart is quite a simple language to master, especially if you have proficiency in prototyping. Slews of real-case projects and a plethora of supporting documents by Google, as well as the generous assistance of a sizeable community, contribute greatly to creating a first-class app. Moreover, the abundance of video tutorials and courses (both by the manufacturer and the unofficial ones on Udemy or Udacity) turn the learning curve into a pretty mild one, which lets even people with no mobile development experience eventually excel in Flutter app development. 
  • Low expenditures. In terms of cost Flutter app has a definite edge over native apps (and not only because you have to pay for building one app only instead of two native products).  

Yet, the overall lower price of building a Flutter app can vary significantly depending on several determinants. 

Factors affecting Flutter app development cost 

Building a custom mobile app is never a bargain-price issue. However, you can save a lot if you approach the process by being aware of the three vital factors that largely determine the sum you will have to fork out.  

Exclusivity 

Technically, Flutter apps can be built for almost any platform (with certain reservations, though: Apple – namely Apple TV – is still inaccessible for customization efforts). But for some of them, the game might be not worth the candle. For instance, if you want to commission an Android smart TV app, you must realize that developers will have to build the entire control logic anew. Why? The touchscreen and mouse operations Flutter relies on don’t dovetail into remote control inputs employed in such smart TVs.  

A Wear OS version of a Flutter app would be a job of work, too, since this platform doesn’t support the lion’s share of development features Flutter utilizes. The complexity of the task and the vast amount of effort in such cases would increase the cost tremendously, so with a specific platform in mind, it is better to think native. 

The range of features 

An app cost is conditioned by the hourly rate a developing company charges. For a developer, creating an app takes a certain quantity of working hours needed to build its features that differ both in number and complexity. Naturally, the fewer and the simpler these features are, the less time a dev will spend creating them, so the cheaper the app is going to cost.  

Some features are easy and swift to create (for instance, login), while others (like photo upload) take an entire working day to build. Other pricey items include payment integration, chatting, and navigation, with the latter taking around 300 hours to develop. Moreover, some native features consume more time to create a cross-platform app. For example, instead of 12 odd hours needed for building AR filters in a native app, Flutter developers would require up to 20 hours to do the same. If such features have little clout for your app, you may leave them out, cutting down on the cost Flutter app development will require.  

Developers’ location 

Developing companies hailing from various regions have different hourly fees for their services.  

Median cost of mobile app development

Today, the biggest sums are charged by North American and Australian companies (from $100 to $200), and a notch lower are the prices of outsourcers from Western Europe. Charges of Latin American, South Asian, and Eastern European firms are more affordable, ranging between $25 and $50 per hour.  

But while choosing an outsourcer for your Flutter app project, the numbers aren’t the only index you should steer by. Equally important is the quality of implementation. On balance, companies from Ukraine tick all the boxes. Offering first-rate services by seasoned talents at reasonable prices, Ukrainian outsourcers can create a product that will meet all your requirements and live up to the expectations of prospective clients. 

All that said, it is important to realize that each app is unique, so gauging your potential expenditures should be done with a view to a concrete project and its envisaged peculiarities. 

Flutter app cost measurement and development fundamentals 

It is not a problem to give ballpark numbers related to Flutter app development cost. Some simple project, say a fitness app with meal plans, workout tips, and weight diary, would cost anything between $25,000 and $35,000. A more advanced app with voice calls involved can be developed for up to $48,000. Integration of more complex features (like Instagram) will start your Flutter app project at $41,000 with the potential to run up to $55,000.  

To arrive at a more precise sum, you should cooperate with the developer. Typically, cost assessment proceeds in the following way. 

Discovery stage 

At this initial phase, you hold meetings with project managers and analysts who, after going through potential risks and solutions to them, come up with a rough estimation of execution terms. The realization of the minimum and maximum time necessary for the completion of the project gives you the general idea of the budget you will have to allocate. It is here that you must decide whether your app is worth making finance-wise.  

Creating the project specification 

Based on the data you provide, outsourcers create a wireframe of the app – the blueprint of a kind where you can see what the UI will look like.  

Only after that, a detailed estimation of the project is possible. Once you agree upon the budget, project provisions, and wireframes, the development phase is kicked off. 

Taking thought of additional expenditures 

The score the developer called is in no way the final amount you will have to fork out. You should be aware of the accompanying expenses. The latter include: 

  • Server space payments. If the server used for processing and storing related data is weak, the app’s performance and consequently UX will be poor. Moreover, unreliable servers tend to be vulnerable to tampering attempts, which can compromise the security of the client’s personal and financial information located there. So, your choice should go to a solid provider, and hiring the services of such facilities exceeds $1,500 a year. 
  • Virtual stores’ charges. How can customers discover your product? Shopping at app stores, of course. These charge for keeping your app on their virtual shelves. To upload your app to Google Play, you are to make a one-time payment of $25. Apple Store’s charges depend on the app kind. If it is a product to be used internally within your organization, the annual fee is $299, but if it is a regular app meant for sale, the fee is considerably lower ($99). Plus, both vendors charge a certain interest for every sale.  
  • Maintenance and update expenditures. Upgrading the product is a necessary summand of its staying atop of app stores’ charts. And the longer an app lives, the more significant sums you will have to invest into updating it. Eventually, you may find that the update expenses exceed the development costs. But as long as the app generates revenues greater than the budget spent, the investment pays off.
