Silent huge FlutterError when no network

I saw huge FlutterError om my Crashlytics backend. It is come form this package.
I can reproduce this issue when no network.

Is there anyway that can silent this kind error ? There are too many error that we cannot focus on real problem.
```
Non-fatal Exception: FlutterError
SocketException: Failed host lookup: 'xxx' (OS Error: nodename nor servname provided, or not known, errno = 8). Error thrown Instance of 'ErrorDescription'.
```

I saw same issue here:
