1.6.0 is the latest preview release being rolled out by Google earlier this month.
As a development platform, cross-platform mobile app development has gained a lot of popularity in the past few years. After seeing the response on cross-platform development from the market, various tools and software have emerged to make the development platform more desirable.
A few examples of such web-based cross-platform app development tools are React Native backed up by Facebook, PhoneGap backed up by Adobe, Xamarin backed up by Microsoft and many more.
With the inception of such efficient cross-platform tools, flutter apps are set to take it to the next level. The purpose of developing flutter cross-platform apps is to minimize effort and time consumption. Other than that, this cross-platform app development platform offers many benefits which have escalated its popularity among the developer's community.
In the growth and popularity of flutter, a major role was played by GitHub, which can be seen in the above graph statistics.
Before diving deep into flutter advantages and disadvantages, know what exactly is the Flutter framework and why it is preferred by developers across the globe.
The flutter programming language is a mobile app SDK (Software Development Kit) that is developed by Google for building mobile applications for major app development platforms like iOS and Android. Flutter comes with a full package that consists of widgets, development tools, and framework to provide the app developers the ease of usage.
Here are some more facts about the flutter development that you should be aware of such as:
So now you know what is Flutter framework, it's time we move towards the flutter pros and cons.
Dart, an object-oriented programming language for fast apps on multiple platforms, is integrated with Flutter to develop apps. Flutter engages reactive views , which tends to refresh the view tree for every new frame. It further develops objects that usually exist for only one frame and Dart uses “generational garbage collection” that is suited for such an environment.
Dart also avoids jank and stutter by allocating objects with a single pointer bump and don’t involve locks. The programming language “tree shaking” compiler make it more efficient for Flutter as it includes on those codes which are required by the app.
The app developers can deploy a wide range for widgets from its library, which help in creating multi-dimensional apps.
With Flutter being one of the best frameworks for the developers across the globe as compared to other frameworks, it has many conveniences that are usually not found in any single framework. Here are some of the elements that make Flutter one of the best frameworks:
The interesting part of Flutter is that not everyone is a fan of Google’s mobile app SDK. That’s why we have decided to state the pros and cons of flutter programming language to see if it has the potential of developing apps as an efficient cross-platform mobile development.
For your ease, we have put down the pros of Flutter first and then have listed cons. Take a look:
Google's flutter software development kit enables developers to build two-dimensional mobile apps that can offer various functionalities and features including storage, camera, and geolocation support to users.
In case, you are looking for some high-quality and impressive designs then flutter is the right choice for your project. Here are the open source mobile app builder’s notable advantages:
The mobile apps developed using flutter app development are way faster in comparison to applications built on other app development platforms. Apps made with flutter are also smooth in functioning as they offer a great user experience without any cutting or hanging while continuously scrolling.
A Minimum Viable Product MVP plays a crucial role as the foundation for mobile and Web applications, so if you want your digital product to be developed at a quicker pace then opt for flutter cross-platform app development.
Many SMEs (Small to Medium-scale Enterprises) and organizations are now using flutter to speed up their development process while reducing the app development cost at the same time.
Hot Reload is considered to be one of the biggest advantages of flutter because of this the app developers are able to see all the changes, including the minor ones in the code right away. With the help of hot reload, app developers can also make quick fixes in the app's code for its smooth functioning.
In flutter, the user doesn't really have to create two separate apps for different platforms like Android and iOS because flutter provides a single codebase that can be used for more than one platform. This ultimately reduces the testing efforts as the Quality Assurance team doesn't need to run the same tests on different platforms again and again.
Setting up flutter is very easy and can be initiated on low-end machines where app developers can access native features like geolocation and camera. This cross-platform mobile app development platform allows you to reuse your existing Objective-C, Swift and Java code for iOS and Android platforms.
Flutter offers faster & more dynamic mobile app development environment to the developer that allows changes in the code, which can be visible directly in the app. This functionality is due to the hot-reloading features that take (milliseconds) to reflect the change.
Faster code compilation also gives greater freedom to add features, fix bugs and experiment faster.
One of the best things about Flutter development is that a single code can be used for two platforms. For instance, a single code can be used for Android and iOS platform both. It’s because Flutter has its own widgets and designs and don’t rely on the platform.
It saves time and efforts of the Flutter developer and yet, the developer can easily differentiate the app even with the same code base.
Flutter doesn’t make use of platform widgets (or DOM WebViews), as it has a whole set of its own widgets that are fast and can be customized as per the developer’s need.
Widgets can be directly rendered from the platform only and further tailored. Flutter just need a platform where widgets can be put on the screen.
The layout structure in Flutter can be regarded as the most considerable improvement. It helps in determining the size and position of the widgets. Earlier, layout used to have a large number of rules that has to be applied to widgets.
For instance, CSS layout defines 375 properties, which are applied to HTML elements.
In comparison to the other mobile app development frameworks, flutter is relatively new and is still in its initial stages of development. So, one can say that it still requires some more time in the application development field to fully compete with other frameworks like Xamarin.
Here are some other disadvantages of flutter framework:
It’s true that Flutter has built an impressive support community with hundreds and thousands of flutter enthusiasts, but it's still not enough. In comparison to other support communities, flutter is lacking behind in user support. Also, there are limited libraries that can be accessed by app developers in the flutter.
Because flutter is still in its early stages, there are not a number of CI (Continuous Integration) Platforms that provide support to it; this includes Jenkins and Travis. That’s why continuous integration support can be referred to as a major disadvantage for flutter development.
Another issue for the flutter app development companies is that it is limited to mobile applications and does not cover Web apps. And this can be a major problem as nowadays businesses are looking for support from both mobile apps and web browsers. Thus, flutter lacks flexibility with respect to web applications.
As we all know, Flutter is relatively new to the app development world and thus, sometimes it’s hard to find the required functionalities in the available libraries. And to cater to that, the developer has to build it by himself, which can well extend the app development time.
Apart from Android and iOS, flutter can also be used to create mobile apps on a new platform known as Fuchsia that is developed by the tech giant Google itself. As per reports, Fuchsia may replace Android in future and will pack more punch than Android.
Ever since the day Flutter made its debut at Google I/O 2017, it has been a topic of interest in the mobile app development industry. Google I/O 2019 drew more attention to Flutter, and many announcements made this technology more lucrative for the app developers. Here are some announcements from Google’s annual developer conference:
Speaking from the point of view of an app developer, flutter does lack some important aspects, but on the other hand, it can be seen that Google is paving a new road for cross-platform app development. Our expert advice would be to give flutter a try as it's still in beta stage and will surely improve in the upcoming months.
So, this was our take on the pros and cons of flutter and its entry in the mobile app development market. If you are interested in reading more such informative articles on cross-platform app development then make sure you are subscribed to MobileAppDaily for daily updates.
