Does somebody know why vs code show this error?
lib/net/flutterfire.dart:49:43: Error: The operator '[]' isn't defined for the class 'Object'.-
- 'Object' is from 'dart:core'.-
Try correcting the operator to an existing operator, or defining a '[]' operator.-
double newAmount = snapshot.data()['Amount'] + value;-

Thanks, great tutorial. I have a question: will it be possible to retrive some info from firebase data bypassing the pin authentication? This is the scenario: some informations about the person who just suffered a stroke and can't use the phone but the the helping team could use - blood group, allergies

Awesome video. Please in your next video can you show us the snippets in the documentation so we don't have to try and memorize these codes. It will really help to know where in the docs we can find these code examples. Thanks

I'm getting an error here in Android studio, and I don't know how to resolve it too, it says type[] can't be assigned to document.data() and it also shows the same error in the addcoin function where we have snapshot.data()

Do we need to commit the downloaded google-services.json and .plist files to commit history? Or are these private credentials that should not be committed?

Null safety problems all over the place when trying to apply the 'signIn' and 'register' Future functions.
Anyone else having those problems?
