loadingImage property

String? loadingImage
final

Optional image swapped in while the button is in its loading state (after the user taps and before onPressWithCompletion's complete is called).

While loading, this image rotates clockwise on the CarPlay display. When omitted, the button rotates its normal image instead.

Accepts the same formats as image (asset path, SVG asset, file:// path, or network URL). In-place image updates require iOS 26.0+ — on earlier systems the loading rotation is skipped natively.

Implementation

final String? loadingImage;
