Not showing banner

Bug report

It doesn’t display any banner and if I refresh the state of my app it throws an error and closes it

Steps to reproduce

I followed exactly the same steps described here: https://youtu.be/yll3SNXvQCw?t=13995

Expected behavior

I should see the banner

Additional context

You can see the empty block without banner here at the bottom:

banner != null
                  ? Container(
                      color: Colors.white,
                      height: 50.0,
                      child: AdWidget(ad: banner),
                    )
                  : Container()

If I refresh at this point this is the error that I get before losing the connection with the emulator:

@erperejildo I did not see such behavior, If you do feel free to raise another issue with the appropriate reproducible steps.

Thanks

[erperejildo]

@erperejildo did you figure this out, i’m having the same problem, also used to work with the previous firebase package here?

No, and I have to say that I also created a new project from scratch and copied my files to it
