Brother... If its possible could please explain...
the part where we used the Map.
Can't we fetch the data without the Map ?

Well.. I'm a little confused.. by its use...

[dhruvrajani]

in stream builder if we remove all the data then it will show error (type "null" is not a subtype of type "Map<dynamic, dynamic> ") . so how can I solve this?

[chiragmakwana]

brother i got an error, type 'List<Object?>' is not a subtype of type 'Map<dynamic, dynamic>'. What's the Solution for this?

[kno]

Holy moly, it took me forever to got this running :(
Thanks for the video!!!

I still do not understand why it is necessary to write "as dynamic" for the map but that helped me to fix it!

Thanks!

[thushankalana]

Sir, How to pass realtime data base values into List🙂

[kailanirochellla]

solution of the ""Map<dynamic, dynamic> "" is
Map<dynamic, dynamic>? map = snapshot.data!.snapshot.value as Map<dynamic, dynamic>?;

if (map == null) {
return Center(child: Text('No data'));
}

List<dynamic> list = map.values.toList();
return ListView.builder(
itemCount: list.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(list[index].toString()),
);
},
);

[abdullahranjha]

Expanded(
child: StreamBuilder(
stream: ref.onValue,
builder: (context, AsyncSnapshot<DatabaseEvent> snapshot) {
if (!snapshot.hasData) {
return CircularProgressIndicator();
} else {
Map<dynamic, dynamic> map =
snapshot.data!.snapshot.value as dynamic;
List<dynamic> list = [];
list.clear();
list = map.values.toList();
return ListView.builder(
itemCount: snapshot.data!.snapshot.children.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(List[index]['title']),

);

});
}
},
)),
