Flutter Dropdown Item List
To create a dropdown item list in Flutter, you can use the DropdownButton
widget along with the DropdownMenuItem
widget. Here's an example code snippet:
DropdownButton<String>(
value: selectedValue,
onChanged: (String? newValue) {
setState(() {
selectedValue = newValue;
});
},
items: dropdownItems.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: Text(value),
);
}).toList(),
)
In this code snippet:
- selectedValue
is a variable that holds the currently selected value from the dropdown.
- dropdownItems
is a list of strings that represents the items in the dropdown.
You can replace String
with the appropriate data type for your dropdown items. Remember to update the onChanged
callback to handle the selection of a new value.
Please note that this code snippet is just an example, and you may need to customize it based on your specific requirements.
