Material3 Alert Dialog actions not centered

Question

Im making a alert dialog to with 2 buttons, in material2 the alignment for alertdialog worked normally and the two buttons are centered, but once i updated to material3 version, both buttons are aligned to the right side, adding actionsAlignment does not fix the problem or move the buttons at all. here is how it looks like currently:

I want the "Scan with Camera" and "Read from image" buttons to be centered horizontally. Code:

AlertDialog(
      actionsAlignment: MainAxisAlignment.center,
      alignment: Alignment.bottomCenter,
      actions: [
        Text("Testing"),
        // scan with camera
        TextButton(
            onPressed: () {
            },
            child: Text("Scan with Camera")),
        // read from image
        TextButton(
            onPressed: () {
            },
            child: Text("Read from image"))
      ],
    ))

The actionsOverflowAlignment uses OverflowBarAlignment.end by default. In order to have them on center, use

 AlertDialog(
   actionsOverflowAlignment: OverflowBarAlignment.center,
