In Google Developer Days in China, Google today announced the definitive preview of the Flutter developer, the company’s open source mobile user interface structure that allows developers to create native interfaces for Android and iOS. Flutter Release Preview 2 is the last major milestone before the constant release of Flutter 1.0, which will be released later this year.
If you already have Flutter installed, simply enter the Flat Upgrade command to get the latest build. If not, follow the detailed procedures for Windows, Mac OS or Linux. R if you have not good knowledge then can get best solution from Mobile App Developers.
This is the sixth preview. Flutter was announced for the first time in May 2017 at the Google I / O developer conference as the first of Alpha. The first beta appeared in February, followed by two more and two release previews. The library is designed to compete with frameworks like Facebook’s React Native. It is designed to combine Native Mobile’s power and platform integration with the rapid development and multi-platform reach of portable UI toolkits. The flattest apps are created using the Google Dart programming language.
Flutter release preview 2
Flutter Release Preview 2 provides support for running darts in the background, even when the application is paused. Plug-in authors can use it to create new plugins that activate the code when an event is triggered, such as, for example, activating a timer or receiving a position update.
This version also reduces the size of the application package on Android and iOS up to 30 percent. The minimal Flutter app package on Android now weighs 4.7MB, saving 2MB from the beginning of the Flutter project (further optimizations are underway). On iOS, mileage may vary due to the way iOS packages are created.
On the other hand, Preview 2 promises iOS app accurate to the pixel. Although Flutter is an agnostic for every single user interface theme, for teams looking to create applications that follow Apple’s user interface guidelines, this release adds support for the “Cupertino” theme controls in Flutter to specific iOS widgets and classes.
Google says that the new developers continue to use Flutter. The company notes that thousands of Flutter-based apps have already entered the Apple App Store and Google Play prior to version 1.0, including some of the most popular in the world: Alibaba (Android, iOS), Tencent Now (Android, iOS) . and Google Ads (Android, iOS).
For more information on Flutter, Google offers a variety of resources, including examples, interactive videos, newsletters, community articles, developer shows, discussion groups, chat rooms, community support, and a weekly online hangout.
