You can place style-specific images into separate folders and if you
have some different images in style for os you can check
Qt.platform.os and select the appropriate image:
https://doc.qt.io/qt-5/qml-qtqml-qt.html#platform-prop
For example, you have:

+material/img_ios.png
+material/img_android.png

Image {
    source: Qt.platform.os === "ios" ? "img_ios.png" : "img_android.png"
}

It depends on what part you share and what is specific. It could be
the other way, that you have mostly identical resources for different
styles, but all highly os-specific. Then you can place it in
os-specific folder and in some cases select proper image for current
style using ?: expression.

In most cases you need white icons for the app bar and other icons are
tinted with some color, so you can just use white icons :)
