Deleting a Firestore Document in Flutter
There is no need for a huge story here. Deleting a Firestore document is a straightforward thing. We just have to point to a doc and call delete on it. final _db = FirebaseFirestore.instance; await _db.collection("notes").doc("note1").delete(); That’s it. The pointed document will be deleted by the above function.

Updating documents in Firestore is pretty easy. One method is to use the update function available in Firestore Library.

Persisting Data on Firebase Emulator
Firebase Emulator Suite is a great tool to develop with Firebase locally. It allows us to even use Firebase Functions without the paid Blaze plan. But by default, Firebase Emulators don’t store any data. That is, if I ran Firebase Auth Emulator and created a User when I run It next time, The User would’ve been deleted. Or, All those Notes you created in Firestore would’ve wiped. I don’t know about you, It is a mess to play with Emulator UI to add mock Data.
