You can refer to this medium article, they have explained how to use StreamBuilders with Firebase RTDB.

同时，这是从同一篇文章中获得的片段代码...

In the meantime, here's a piece code derived from the same article...

//first make a reference to your firebase database

var recentJobsRef = FirebaseDatabase.instance
.reference()
.child('recent')
.orderByChild('created_at') 
.limitToFirst(10);

//then use StreamBuilders like this

StreamBuilder(
stream: recentJobsRef.onValue,
builder: (BuildContext context, snapshot) {
if(snapshot.hasData) => return "Has Data";
else if(snapshot.hasError) => return "Error";
}
