Flutter, Google’s new toolkit for building a more interactive native user interface for Android and iOS receives its final preview. On, Thursday, the company kicked off Flutter Release Preview 2, which is the final release before the Flutter 1.0 launch.

Google has introduced Flutter for the developers to build more convenient and brand-driven app design. The tool offers exclusive features that make it possible for the Android and as well iOS developers to create interactive app designs. However, still, some of the developers told Google that they want to build the iOS applications that strictly follows the Apple interface guidelines. To make this possible Google has added support for more iOS themed widgets and libraries based on ‘Cupertino’ controls in Flutter Release Preview 2 and named the version, ‘Pixel-Perfect on iOS’. Now, with access more extensive widgets and libraries, developers can easily build iOS apps following the Apple guidelines subjected to the interface.
Now, Flutter comes with the following widgets for developing iOS apps.
Along with the iOS themed widgets, the company has also made some other changes for the developers in the Flutter Release Preview 2. Google has also added the support for the execution of Dart code in the background. This means now the Flutter app will be able to run or activated by plugins like timers, location and other triggers offered by the OS.

Now, the Flutter comes with 30% lesser size for both Android and iOS than its previously launched versions. The Flutter application package size is available in 4.7MB as the company has scraped off 2MB by optimizing the APK/IPA for the developers. Besides, the team is still seeking the further possibility of optimizing the tool.
