select_dialog package

package designed to select an item from a list, with the option to filter and even search the items online.

pubspec.yaml

select_dialog: <last version>

import

import 'package:select_dialog/select_dialog.dart';

simple example

string ex1 = "no value selected";

selectdialog.showmodal<string>(
  context,
  label: "simple example",
  selectedvalue: ex1,
  items: list.generate(50, (index) => "item $index"),
  onchange: (string selected) {
    setstate(() {
      ex1 = selected;
    });
  },
);

attention

to use a template as an item type, you need to implement tostring, equals and hashcode, as shown below:

class usermodel {
  final string id;
  final datetime createdat;
  final string name;
  final string avatar;

  usermodel({this.id, this.createdat, this.name, this.avatar});

  @override
  string tostring() => name;

  @override
  operator ==(o) => o is usermodel && o.id == id;

  @override
  int get hashcode => id.hashcode^name.hashcode^createdat.hashcode;

}
