Google launches Flutter Beta 3, its Android and iOS mobile app SDK

Ahead of its I/O 2018 developers conference, Google has launched the third beta release of Flutter, its open source mobile UI framework that helps developers build native interfaces for Android and iOS. The Flutter SDK has also gained official support from the Material Design team.

Flutter was first announced as an early alpha at I/O 2017 in May, and only arrived as a beta in February. Meant to compete with frameworks like Facebook’s React Native, the library is designed to combine the performance and platform integrations of native mobile with the rapid development and multi-platform reach of portable UI toolkits. Flutter apps are built using Google’s Dart programming language.
