Google’s new cross platform mobile SDK, Google Flutter, has had its first Release Candidate build released for developers to use and test. Flutter was announced way back in February at Mobile World Congress and it is aimed to give developers a leg up in developing mobile apps that are native for both Android and iOS.
The beauty of Flutter is that it comes packing its own rendering engine and framework which, in essence, bypasses the native UI frameworks in both platforms. This is not something new for developers, especially game developers who have used different rendering engines. This allows for significant performance increases (particularly on Android). When you compile the app with the available Android and iOS SDKs, you get the appropriate app & framework for the respective platform.
What this means for end users is that app performance on Flutter built apps should be better and you should have a native experience with apps regardless if you are on Android or iOS.
If you have the Flutter platform installed, you can issue a simple command within it to get upgraded. If you want to install it, head over to the Flutter.io site to get all the details and requirements.
