`final dbRef = database.child("Blocos");
dbRef.onValue.listen((event) => {
event.snapshot.children.forEach((child) {
if (child.key != null) {
item.add(child.key.toString());
}
})
});
print(item);
when I print it only appears [], how do I make a list of the type [word1, word2] appear? I intend to use the list to make a dropdownbutton afterwards.
first, you need to check, is "blocos" has data or not. You can print on event curly brackets first. I think, the mistakes is you're not make sure, is "blocos" has data or not. Hopefully can help you. Thank you
