Hello! Thanks for the video. How would you update the values on Firestore instead of printing them in the debug console? Thanks

Hello! thanks for the tutorial. I have a big doubt, how do you keep the selection? because you select one, but later this back to initial state.
Thank you!

The Widget works fine, but once you select the items and if you want to change it again, and when you click the dropdown again it will display the original hardcoded initial values... Is there a way to update the initial values to previously selected values?

Thank you price for the great tutorial.

Solution for keep selected value.

---> I have add initState() for populateMultiselect().

@override
void initState() {
super.initState();
populateMultiselect();
}

Set<int> selectValues = Set();
void _showMultiSelect(BuildContext context) async {
//multiItem = [];
//populateMultiselect();

final items = multiItem;
// final items =
// MultiSelectDialogItem(1, 'India'),
// MultiSelectDialogItem(2, 'USA'),
// MultiSelectDialogItem(3, 'Canada'),
// ];

final selectedValues = await showDialog<Set<int>>(
context: context,
builder: (BuildContext context) {
return MultiSelectDialog(
items: items,
initialSelectedValues: selectValues.toSet(),
);
},
);

for (int value in selectValues.toSet()) selectValues.remove(value);

print(selectedValues);


}


Thank you...
