var firebaseRef = firebase.database().ref("members");
firebaseRef.orderByChild(userKey).equalTo(true/false).on("child_added", function(Data){
console.log(Data.val(), Data.key);
}

i am assuming that you are already aware of on or once method and child events also, if not then read them(documentation), will help you a lot, otherwise above code will do your job
