I want to change the background color **transparent** that I show in the image.

[Here](https://i.stack.imgur.com/ZMlzB.png)

CurvedNavigationBar versions:

```
curved_navigation_bar: ^0.3.2

```

Here are the codes I tired:

```
backgroundColor: Color.fromRGB0(255,255,255,0),
backgroundColor: Color.fromARGB(0,255,255,255),
backgroundColor: Colors.transparent,
backgroundColor: Colors.white.withOpacity(0),
backgroundColor: Colors.black.withOpacity(0),

```

None of them worked. How should i go about.
Thanks...
