问题 I am trying to create a BLOC which depends on two other time based bloc and a non-time based bloc. What i mean with time based is, for example they are connecting a remote server so it takes time. It's working just like this: Login (It's of course taking some time) If login is successful Do another process (This is something takes time also. It returns a future.) After login and another process finishes, let the page know it. My BLOC depends on these three: final UserBloc _userBloc; final

问题 I'm trying to catch symbols in a dart Regexp. My regexp looks like this: RegExp containsSymbolRegExp = RegExp(r"[-!$%^&*()_+|~=`{}\[\]:;'<>?,.\/]"); However, I also need to make it catch the symbol " I can't stick " in there though, since it messes with the string. Any ideas how to do this? Thanks. edit: jamesdlin's answer works great for dart. But it doesn't work for my flutter app, so I'm thinking it has something to do with flutter.

The integration with firebase is working, probably the problem is on textformfield that is not getting data... import 'package:cloud_firestore/cloud_firestore.dart'; import
