How can i auto switch to micro-focus camera on iphone 15 pro

[godfeather]

Dear every qr_code_scanner developers:
When I close to small qr code, the camera may auto switch to micro-focus camera;
but now i can't get the focus while my camera close to small qr code, because it always use the 1x camera。

Plugin Version: qr_code_scanner: ^1.0.1
I can only switch camera from back to front or front to back

Thanks in advanced.
