Internet search giant Google has acquired Flutter for a reported US$40m, to possibly integrate the start-up's gesture-recognition technology into its Chromebook laptops and Nexus handheld devices.

Google has released Flutter 3.7, an update to the company’s open source, cross-platform development framework that adds custom menu bar support and previews a new rendering engine for iOS apps.

Google is announcing a number of new features for Flutter, which hit its 3.0 milestone at last year's I/O and is now launching version 3.10.
