The digital world is evolving at a very fast pace and customer demand for faster, better apps is putting a lot of pressure on businesses. In this scenario, what an app development company needs is easy-to-use, intuitive technology like Flutter to be able to offer high-end app development services. Moreover, backed by Google, Flutter is evolving at a rapid pace. Let’s learn more.

What is Flutter?

Flutter is an open-source software development kit that Flutter app developers use to develop native-like Android and iOS mobile apps from the same code base, without having to write separately for both the mobile OS. Flutter was launched in 2015 by none other than Google, but for a long time Google maintained its beta stage. In December 2018 is when Flutter was officially launched and it became popular with mobile app developers very quickly. Flutter was developed to get the combination of native apps performance and rapid development and multi-platform reach of UI toolkit. Flutter apps can be developed using the Dart programming language. Today Flutter is among the top software listed on GitHub, and Flutter app development services are being offered by some of the best companies across the world.

What’s the latest development in Flutter?

Google has recently released Dart 2.5 and Flutter 1.9, making Flutter app development services even better and more sought after. That is because Dart 2.5 gives Flutter app development stronger support for C code and intelligent code completion by using machine learning to help Flutter app developers complete their code as well as choose the API they should use. A Flutter app development company can use the latest 1.9 version to build web, mobile, and desktop apps from the same codebase. Flutter 1.9 supports iOS 13 and macOS Catalina, and also comes with updated Material widgets for toggle buttons and filters.

Before we talk in detail about the latest update in Dart, let’s understand what is Dart. It is a programming language also developed by Google and launched in 2011 for developing web, mobile and desktops apps. Dart is object-oriented, class defined, and garbage-collected language, and it uses a C-style syntax that can also compile into JavaScript.

The domain of app development has become very exciting in the recent years with a lot of new languages being launched, and mobile app development companies and web app development companies using emerging SDKs, like Flutter, to build stunning and robust apps. The most recent development in Flutter app development services is Google’s introduction of Dart 2.5 and Flutter 1.9, fortunately coinciding with the launch of iOS 13 and macOS Catalina.

So why are we excited about Dart 2.5?

Dart 2.5 is a more stable version offering two technical previews, i.e. dart:ffi which is a foreign function for calling code C directly; and the second being ML-powered code completion.

Calling Code C

Dart gives support for calling code C, though it is limited to deep integration in Dart VM as it employs Native extensions. Google wants to offer Flutter app developers a new app development solution that performs really well and is compatible with multiple Dart platforms and compilers. With the new release, Flutter app developers can now call into C system API on the host OS and can also call into C library for either a single OS or for both iOS and Android.

Intelligent Code Completion

In Dart 2.5 Google is integrating ML to enable the developers with completing code in real-time, i.e. while they type.

Constant Expressions

Dart 2.5 also allows the Flutter app development company to use multiple ways to find constant expressions as well as use casts, new control flow and spread features, because the new Dart uses extension methods and references for non-nullable by default along with enhanced concurrency support.

Flutter For Web

Google has also combined Flutter’s web repository with the main repository. This makes the work really simple and easy for Flutter app developers as they can use the same codebase for desktops and any kind of mobile devices.

ToggleButtons

In the new Flutter, the ToggleButtons widgets come with a row of ToggleButton widget together, consisting of many icon and text widgets. These together make a set of buttons that can be customized in terms of look and functionality.

ColorFiltered

Flutter’s ColorFiltered widget allows the Flutter app development company to recolor a tree of child widgets. This is especially useful for app developers with color blindness issues.

Support for macOS Catalina and iOS 13

With Flutter 1.0 and Dart 2.5, Google has ensured that Flutter works equally well with iOS and macOS as it does with Android by updating the end-to-end tooling experience. This includes support for the new Xcode build system, empowering 64-bit support all through the toolchain, and disentangling stage conditions. Google is also working on IOS dark mode and has blended multiple draw demands officially blended.
