Help needed for how to use Horizontal Multi Drag gesture.
I am making a simple demo app with all the possible gestures included.I have already added all the simple gestures that are included in the GestureDetector widget.Now I am stuck at multi drag gestures. i.e. I need Horizontal Multi Drag gesture to process horizontal drag with minimum of two pointers(fingers).I have found some what relative code snippets on stackoverflow which are not completely useful. No examples or posts out there regarding the Multi Drag gesture s in flutter. Also, The documentation for multi drag gestures is not good enough and doesn't contain any example.I have basically setup a RawGestureDetector with Horizontal Multi Drag gesture recogniser but I am unable to put restrictions like Minimum 2 pointers to start the gesture.As of now it also, considers a single pointer to start the drag event, but I want minimum two pointers to be able to start the gesture, it should not be activated with one pointer.I'd appreciate it if anybody could help me out with this issue.Let me know if any additional details are required.Thanks in advance.

For your Flutterfire-powered Flutter apps, did you create a Firestore shim so that you can more easily migrate to another database later?
I'm building a Flutter app backed by Firebase. I'm using Auth, Firestore, and Storage. I'm sure I'll be writing cloud functions soon enough, too. Originally I was going to use a graph database for this but I decided the added complexity of organizing my data correctly in Firestore would be offset by not having to maintain my backend nearly as much.Looking forward, I'm thinking it would probably be valuable to put all Firestore queries and transactions behind an internal database connector so if I ever want to switch to a new database I can do it with as little headache as possible. Has anyone done this? Are there any tools for Dart/Flutter that will assist in building APIs from models? I've used tools like this in Go to auto-generate boilerplate APIs from structs.Right now I think the approach I'd like to take is just have a db.dart file that adds CRUD methods to my existing model classes but it appears that's not possible in the way I want to implement it yet.I'd like to hear about ways people have implemented this or any graceful ways to solve it.

What topics of Flutter do you guys want tutorials about?
I've been wanting to make flutter tutorials for a while now, since people have been requesting me it for a long time, ever since I started posting some of the examples I had built. It's been a while and the flutter community has grown a lot, and you can find tutorials pretty much about anything. However, I find that beautiful and smooth UI interactive animations like the Fluttery channel used to make are still quite rare in the community, and since that's what I like to do the most, I might do that. I also want these tutorials to be a little bit more on the intermediate/advanced side since there's a lot of tutorials for beginners already. So what do you guys think?
