DropDownTextField.multiSelection not updating textfield after setDropDown

[sharpsaravanan]

MultiValueDropDownController value changes after calling setDropDown() (checkbox reflects the change) but textfield ui is not reflecting the change. I can't find any solution please can some one help me.

Example app

floatingActionButton: FloatingActionButton.extended(
onPressed: () {
_cntMulti.clearDropDown();
_cntMulti.setDropDown([
const DropDownValueModel(name: 'name1', value: "value1")
]);
},
label: const Text("Submit"),
),
