Flutter Firestore add new document with Custom ID

Question

How to add new document with custom id using Dart and Flutter?

PS: I can add new document to collection but its id sets randomly, using this code

Answer 1

You can use set() function instead of add().

Here's full code:

final CollectionReference postsRef = Firestore.instance.collection('/posts');

var postID = 1;

Post post = new Post(postID, "title", "content");
Map postData = post.toJson();
await postsRef.doc(postID).set(postData);

I hope that help anyone.
