How to Display a Widget Over the Screen in flutter?

Question

I want to Display a Widget like this over the Image/Screen:

I try to do this with snackbar with following code:

SnackBar(
  elevation: 5,
  padding: const EdgeInsets.all(0),
  backgroundColor: Colors.transparent,
  behavior: SnackBarBehavior.floating,
  content: Children()

But it is displaying with a little black color in background...

Is there any other widget for achieving this???

If you know the answer of the question then answer this question...

You can also use Toast in this case. A toast generally appears for 2 seconds or you can set a custom duration for the same.

Flutter Toast is a good library to achieve the same.
