setIncomingWallpaperHandler method

void setIncomingWallpaperHandler(
  1. IncomingWallpaperCallback? handler
)

Registers a callback invoked when an external app (e.g. Photos/Gallery) hands this app an image via an Android ACTION_SET_WALLPAPER / ACTION_ATTACH_DATA intent carrying a content:// URI.

Pass null to clear the handler. The default implementation reports absence of the feature; platforms that support receiving such intents should override this.

Implementation

void setIncomingWallpaperHandler(IncomingWallpaperCallback? handler) {
  throw UnimplementedError(
    'setIncomingWallpaperHandler() has not been implemented.',
  );
}
