I created a dropdownButton to allow users to select from a dropdown list which will be populated from an API. For now I am populating using a list I created.
Currently the button is displaying the items from my list but after a selection has been made the list doesnt show the selected item and still shows the hint text. What I would like to happen is after a selection has been made then the dropdownButton shows the item that was selected instead of the hint text.
in the onChanged method I added a setState in hopes of updating the _selectedValue variable to the value that was selected and displaying it in the dropdownButton.
I also added a print statement in my setState method and that does trigger and show me the value within the value variable.
Here is my code.
List<DropdownMenuItem<int>> listItems = [DropdownMenuItem(child: Text("2016"), value: 2016,), DropdownMenuItem(child: Text("2021"), value: 2021,)];
int _selectedValue;
body: DropdownButton(
value: _selectedValue,
items: listItems,
hint: Text("Select Year"),
onChanged: (int value){
setState(() {
_selectedValue = value;
print(value);
});
},
),
