i been trying to convert my app to new flutter new version but i got this error The argument type 'Object?' can't be assigned to the parameter type 'List' that can't be fix.... can somebody help me fix this problem
list() {
return Expanded(
child: FutureBuilder(
future: employees,
builder: (context, snapshot) {
if (snapshot.hasData) {
return dataTable(List<Url>.from(snapshot.data));
}
if (null == snapshot.data || snapshot.data == 0) {
return Text("Tiada Data");
}
return CircularProgressIndicator();
},
),
);
}
It is because you need to cast the type of your FutureBuilder. Based on your code I deduce that employees is of type Future<List> or at least Future<Iterable> then you should define the type of your builder like this:
FutureBuilder<Iterable>(
future: employees,
builder: (context, snapshot) {
if (snapshot.hasData) {
return dataTable(List<Url>.from(snapshot.data!));
}
// ...
},
),
