Why opt for Flutter mobile app development?
-
Cost effective
Flutter's single codebase for both Android and iOS means you only need one software development team to develop and manage your cross platform apps. This keeps developer hourly costs down and reduces the time required to complete Flutter projects and fixes. Compare this to native app development, where an iOS version is developed independently of an Android version, doubling the build cost.
-
Quicker go to market
The cross platform mobile app development tools allow developers to create an app for Android and iOS quickly and easily. Development times can be halved, which means digital businesses can bring app solutions to market faster and gain a competitive edge.
-
Appealing User Interface
The framework offers a set of distinctive and attractive widgets, and the libraries are frequently enhanced with new interface components. In this way, a smaller development team can more quickly build a beautiful native app on both Android and iOS without necessarily the input from a creative designer.
-
Beyond mobile apps
Flutter applications can run on mobile as apps and also on web browsers. Flutter makes it possible to launch your ideas as web and mobile apps from the same codebase. Developers can fix bugs on multiple platforms simultaneously for mobile, web and Apple devices.
-
Simplicity
Anything that a native app can do, a Flutter built app can do too. And if OS features are not available as a plugin, Flutter can establish communication between its Dart programming language and the native code. Flutter offers typical OS features like GPS coordinates, sensor data collection, permission handling, Bluetooth, plus other features in plugins supported by Google.
-
Community Support
Google continuously supports developers with updates and fixes. At the last count, Flutter had 154,000 Stars and thousands of experts on GitHub. Its developer community shares its knowledge and experience to allow for quicker development and faster learning. Additionally Google organises events to teach brands how Flutter can help to grow their businesses.
-
Just like native mobile apps
Flutter apps are very similar to native apps, as no intermediate code interpretation is required. The software renders using Skia, an internal graphics engine, for fast, well-optimised builds not seen in most other mobile app frameworks. And it's perfect for mobile apps as it can deliver advanced custom UI designs seamlessly for both Android and iOS.
-
Faster Coding
Flutter’s hot reload allows engineers to check the effects of code almost immediately, making app creation time quicker than others. In addition, its customisable kit of widgets makes it simple and faster for a Flutter development company to create applications.
