Context: In the frontend the user can enter of delete dates for availability. This is how I added a date:
Firestore.instance.collection('availableDates').add({
'availableDates':date});
But I also need to delete a document
from a collection
in Firestore
. I don't know the document
id but I know the the field value
which is unique. How would I go about deleting the document if I know the field value within the document. Here is a screen shot of firestore:

You can fetch the document first and then delete the document. For example:
var collection = FirebaseFirestore.instance.collection('countries');
var snapshot = await collection.where('city', isEqualTo: 'CA').get();
await snapshot.docs.first.reference.delete();

If anyone is confused after the update of why this code is not working please refer to this one. Update of March 21st, 2021.
refUser.where("city", isEqualTo: "CA").get().then((snapshot){
snapshot.docs.first.reference.delete();
});
I took a bit of time myself to get around this but if it helps even a single person stuck like me then it's all worth it. :)
