Flutter: Firebase database exception on permission denied

[zoechi]

Steps to Reproduce

In Firebase when I access a path where I don't have sufficient permissions,
I get

[  +43 ms] W/RepoOperation(10726): setValue at /test_db/joinRequestCreate/hFWyZYmtgocsWs69TnpHXuEbBRv1/-Kyz7h7zFCbqxZKNrdOD failed: DatabaseError: Permission denied

as log output, but that's easy to miss.

I think there should be a way to get an exception on the client side for permission denied

firebase_database plugin version 0.0.14

Catching crashes and reporting them as errors for this plugin is a reasonable developer expectation.

I'd be happy to review pull requests for this functionality, if anyone has the time.
