Description

I'm trying to execute flutterfire configure . but I get "Exception: UnsupportedError not found in web". Instead of web, the error message could show any platform. It's simply the last registered platform.

Steps to reproduce

1. Clone https://github.com/flutter/ai
2. Nagivate to examples, (e.g. with cd examples)
3. Run flutter pub get
4. Run flutterfire configure ., always use default setting

Expected behavior

Runs without any issues.
