Update examples in README

[alexeyinkin]

The first example is:

showTopSnackBar(
    context,
    CustomSnackBar.success(
      message:
          "Good job, your release is successful. Have a nice day",
    ),
);

This does not build because the first argument requires OverlayState instead of BuildContext.
Other examples should be updated too.

I am also having same issue.
My example below worked fine till I upgraded flutter.

 showTopSnackBar(
        context,
        const CustomSnackBar.success(
          message: "Successful",
        ),
      );

Now I have below message.

The argument type 'BuildContext' can't be assigned to the parameter type 'OverlayState'.

Hi

Hi,
If you haven't resolve your problem yet.
There is the solution you should apply

OverlayState? state = Overlay.of(context);
if (state != null) { showTopSnackBar(state, _buildSnackBar(translatedMessage, snackBarType)); }

Just a simple precision

• _buildSnackBar(...) here is a custom method i have written to display specific type of alert so for your work you can just continue using CustomSnackBar with their static methods (info, success...)

Hope this resolve your problem.
