Manager Filtering Issues

[WhoIsConch]

I'm trying to use Managers for some queries on my database. In a specific query, I'm using a datetime column on one of my database objects that I want to filter. At first, I wanted to do something like this:

final occurrence = db.managers.transactions.filter((t) => t.recurringTemplateId.id(transaction.template.id) & t.date.isBeforeOrOn(_selectedDate));

However, there are some issues with this query:
First, the & operator doesn't seem to work. An error shows up, The operator '&' isn't defined for the type 'Expression<bool>'.
Second, despite the fact that VSCode's autocomplete picks up the isBeforeOrOn method of t.date (of type ColumnFilters<DateTime>), after I actually put in the method VSCode stops recognizing it and says there's no method there, The method 'isBeforeOrOn' isn't defined for the type 'ColumnFilters'. I looked through existing issues and noticed it might be recommended to use computed fields for more complex queries. While I'm not computing any extra field, exactly, I tried to give this a shot anyway. Even then, when trying to filter with GeneratedColumn<DateTime>.isSmallerOrEqual, this method too seemingly decides to disappear once I try to actually use it.

So, maybe I'm just not using managers properly. Or maybe there's a bug here, or VSCode's intellisense is acting up. I'm betting on the former, but it's confusing since I'm using the manager's filtering exactly as shown in Drift's docs. The date time column is nothing special, either, it's just a regular DateTimeColumn get date => dateTime()(). Please let me know if I'm misunderstanding managers, or if something odd is going on!

I'll be happy to take a look. Your query looks correct, so something funny must be going on.
What versions of drift, drift_flutter, build_runner, flutter, etc are you running?
Can you provide me with a tiny reproducible piece of code, and I'll be happy to take a look!

Thanks for your response. I realized the issue was actually very silly, and I just overlooked it. When trying to use these methods, VSCode was importing each method individually instead of just having the whole Drift package imported.
