I want to know the significance of 1.0 in import bb.cascades 1.0
in main.qml
file in BB10 app development project.
thanks in advance.
The 1.0 is the version number.
At the moment there is only version 1.0 of the bb.cascades library. The purpose of this would be for future compatibility, so that if a phone has a new bb10 OS with any major changes to the cascades library your app will still work as it tells the OS it's built for version 1.0.
