[Calendar] Unable to use clientViaUserConsent on Flutter Web

I am trying to create a client for obtaining permissions for a user's Google Calendar.
A snippet of the code is:

```
await clientViaUserConsent(myClientID,
[CalendarApi.calendarScope], launch)
```

Where `launch` is a function from https://pub.dev/packages/url_launcher.

Everything works on Android and iOS, yet, on a web browser, I get the error
`Error: Unsupported operation: ServerSocket.bind`

Package versions:
googleapis: 1.0.0
googleapis_auth: 0.2.12+1
