Google engineers have built a UI framework to help developers build cross-platform 2D mobile apps.
Called Flutter, the open source project is not an official Google technology at this time. Described as being in its early stages on one GitHub page, the project supports development of both iOS or Android apps, according to an online FAQ.
"Flutter is different than most other options for building cross-platform mobile apps because Flutter uses neither WebView nor the OEM widgets that shipped with the device," the Flutter.io site says. "Instead, Flutter uses its own high-performance rendering engine to draw widgets."
