The first "V" of "VisibleArea" in the Flickable documentation should be small latter

https://doc.qt.io/QtForMCUs-2.4/qml-qtquick-flickable.html

In the documentation above, "VisibleArea" is written as "VisibleArea."

However, when the user actually use it as is, the application won't build.

To be able to build, one should use "visibleArea," like so.

Flickable {
    id: flickable
    anchors.fill: root
    // VisibleArea.heightRatio: 1 <= error
    visibleArea.heightRatio: 1 // <= works
    ListView {
        // ...
        }
    } 

To avoid confusion, all "VisibleArea" should be written as "visibleArea" in the documentation as well.
