I was working on my firestore functions. It went fine until today's flutter upgrade. After upgrade "firebase deploy" is not working anymore:

```
    $ firebase deploy

=== Deploying to 'project-id'...

i  deploying database, storage, firestore, functions, hosting
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint /Users/username/Desktop/projects/project/functions

Error: Error parsing triggers: Cannot find module 'firebase-admin/lib/database'
Require stack:

Try running "npm install" in your functions directory before deploying.

```

Tried posts with similar topics on stackoverflow but they didn't work for me. Tried "npm install" from both project and functions directory, I beleive I have latest firebase-admin package, but still getting this error. Any hint is appreciated.
