Custom dropdown flutter with checkbox
587
Follow The link Flutter Dropdown.
And if you don't want searchable just set -> showSearchBox: false,
And the second thing is that you have to replace the icons with flutter checkbox.
Use these two features in DropDownSearch()
dropdownBuilder: _customDropDownExample,
popupItemBuilder: _customPopupItemBuilderExample,
And these are -
Widget _customDropDownExample(
BuildContext context, UserModel? item, String itemDesignation) {
if (item == null) {
return Container();
}
return Container(
child: (item.avatar == null)
? ListTile(
contentPadding: EdgeInsets.all(0),
leading: CircleAvatar(),
title: Text("No item selected"),
)
: ListTile(
contentPadding: EdgeInsets.all(0),
leading: CircleAvatar(
// this does not work - throws 404 error
// backgroundImage: NetworkImage(item.avatar ?? ''),
),
title: Text(item.name),
subtitle: Text(
item.createdAt.toString(),
),
),
);
}
and second one is -
Widget _customPopupItemBuilderExample(
BuildContext context, UserModel item, bool isSelected) {
return Container(
margin: EdgeInsets.symmetric(horizontal: 8),
decoration: !isSelected
? null
: BoxDecoration(
border: Border.all(color: Theme.of(context).primaryColor),
borderRadius: BorderRadius.circular(5),
color: Colors.white,
),
child: ListTile(
selected: isSelected,
title: Text(item.name),
subtitle: Text(item.createdAt.toString()),
leading: CircleAvatar(
// this does not work - throws 404 error
// backgroundImage: NetworkImage(item.avatar ?? ''),
),
),
);
}

Benyamin over 2 yearsaccording to this page stackoverflow.com/questions/53150219/… you can do something like this and set this property of dropdown menu like this: decoration: ShapeDecoration( shape: RoundedRectangleBorder( side: BorderSide(width: 1.0, style: BorderStyle.solid), borderRadius: BorderRadius.all(Radius.circular(5.0)), ), ),
