Getting null value instead of input value in flutter - flutter

Question

I am receiving a null value when I am saving a value as in my code I have three fields
String? _itemName ="";
String? _dateCreated ="";
int? _id;
and when after running my project, I insert an item by calling this method:
Future<int> saveItem(NoDoItem item) async
{
var dbClient = await database;
int res = await dbClient.insert(tableName, item.toMap());
debugPrint(res.toString());
return res;
}
Using saveItem() function:
void _hndleSubmitted(String text) async
{
_textEditingController.clear();
NoDoItem noDoItem = NoDoItem(text, DateTime.now().toIso8601String());
int savedItemId = await db.saveItem(noDoItem);
debugPrint("Item saved ID: $savedItemId");
}
and after this when I am retrieving all itemNames, I get null value instead of user entered value
Defining getItems() func:
Future<List> getItems() async
{
var dbClient = await database;
var result = await dbClient.rawQuery("SELECT * FROM $tableName ORDER BY $columnItemName ASC");
return result.toList();
}
Using getItems() function:
_readNotoDoItems() async
{
List items = await db.getItems();
items.forEach((item) {
NoDoItem noDoItem = NoDoItem.map(item);
print("Db items: ${noDoItem.itemName}");
});
}
Please tell me what is the the reason that I am getting a null value instead of entered value and how to fix this issue?

Answer 1

I think the problem is here
void _hndleSubmitted(String text) async {
_textEditingController.clear(); // <--------- HERE
NoDoItem noDoItem = NoDoItem(text, DateTime.now().toIso8601String());
int savedItemId = await db.saveItem(noDoItem);
debugPrint("Item saved ID: $savedItemId");
}
you clear the value with _textEditingController.clear(); right before using it. move it after adding the item to database
void _hndleSubmitted(String text) async {
NoDoItem noDoItem = NoDoItem(text, DateTime.now().toIso8601String());
int savedItemId = await db.saveItem(noDoItem);
textEditingController.clear();
debugPrint("Item saved ID: $savedItemId");
}
