Google publishes simultaneously Flutter SDK 1.2 and Dart 2.2



[ad_1]

At last year's CMM, Google announced that its Flutter Application Development SDK was ready to go from alpha testing to beta testing. Today, at MWC 2019, Flutter obtains its second stable version, version 1.2, associated with the release of version 2.2 of the Dart programming language.

Flutter, Google's multi-platform application development kit, allows developers to use the Dart programming language to create great apps for Android and iOS (and soon Fuchsia, Windows, macOS and the Web ). Google promised that Flutter would see a new stable version once a quarter after its initial release on Flutter Live last year.

Flutter 1.2

Flutter 1.2, released today, continues to aim to make the Flutter experience as stable and efficient as possible. Beyond that, the team has strived to offer Flutter a "faithful representation" of many iOS user interface elements, including the text cursor. In addition, Flutter now proudly supports the iOS text floating cursor.

Another interesting addition to Flutter 1.2 is support for the new Android application package, a feature much in demand by Flutter developers. This support should help reduce the initial setup size of your application and allow for more interesting tasks, such as dynamic streaming, that allow users to install additional features.

A big sign of Flutter's success is the number of third-party code contributions. For example, the new Flutter 1.2 App Bundles support was provided by an Intuit developer.

The Flutter team has also invested in a third debugging tool for Flutter and Dart applications, complementary to Visual Studio Code and Android Studio, called Dart DevTools. It's actually a web-based application that allows you to inspect widgets, view logs, and fully debug the application directly from your web browser.

Dart 2.2

The developers of Flutter and Dart will be happy to know that Dart 2.2 is also available today. Flutter developers should note that Dart 2.2 improves performance by 15 to 20 percent. In addition, the language has acquired the ability to write Set literals using {} braces, similar to Python and other languages. This creates a set as a constant.

Dart 2.2 is available for download now and is also integrated with the current version of Flutter 1.2. You can also play with Dart 2.2 now in the official DartPad web application.
