如何从 flutter 中的 firebase 访问文档 ID？

Question

I am working with flutter and firebase. I have a collection with a list of documents, and those documents further have many fields each. I have an API for accessing the documents, which returns a list of the details in each document. But, I want to access the document id of each document. How to do that?

Answer 1

If you write such a query you can have every documentId of your documents.

_getDocuments() async {
await _firestore.collection("yourCollection").getDocuments().
then((myDocuments) {
  for (DocumentSnapshot eachDocument in myDocuments.documents) {
       print(eachDocument.documentID);
    } 
  }
});

}
