firebase - 我可以使用此快照调用访问文档ID吗？

Question

This is the streambuilder im using to access all the documents at once

 StreamBuilder(
        stream: Firestore.instance.collection('projects').snapshots(),
        builder: (context, snapshot) {
          if (!snapshot.hasData) return Text('data is loading');
          return ListView.builder(
            itemBuilder: (ctx, index) {
              return ProjectItem(
                id: snapshot.data.documents[index]['id'],
                title: snapshot.data.documents[index]['title'],
                members: snapshot.data.documents[index]['members'],
                complexity: snapshot.data.documents[index]['complexity'],
                affordability: snapshot.data.documents[index]['affordability'],
                duration: snapshot.data.documents[index]['duration'],
                docid: snapshot.data.document[index].documentid,


              );
            },
            itemCount: snapshot.data.documents.length,
}

Can i use docid: snapshot.data.document[index].documentid to access the document ids individually? if not whats the option? Thanks

您可以通过这种方式获取documentID

StreamBuilder(
        stream: Firestore.instance.collection('projects').snapshots(),
        builder: (context, snapshot) {
          if (!snapshot.hasData) return Text('data is loading');
          return ListView.builder(
            itemBuilder: (ctx, index) {
              QuerySnapshot snap = snapshot.data; // Snapshot
              List<DocumentSnapshot> items = snap.documents; // List of Documents
              DocumentSnapshot item = items[index]; Specific Document
              return ProjectItem(
                id: item.data['id'],
                title: item.data['title'],
                members: item.data['members'],
                complexity: item.data['complexity'],
                affordability: item.data['affordability'],
                duration: item.data['duration'],
                docid: item.documentID, // Document ID
              ); 
            },
            itemCount: snapshot.data.documents.length,
          );
        },
      ),
    )
