Error if removing from `items` the currently selected `value`

[JChrist]

If attempting to remove from the items the currently selected value, a RangeError will be thrown. A very small app to demonstrate this is the following. If you select the last item and then attempt to remove it from the items (clicking the remove last item button) the RangeError will be thrown.

import 'package:flutter/material.dart';
import 'package:searchable_dropdown/searchable_dropdown.dart';

void main() {
  runApp(App());
}

class App extends StatefulWidget {
  App();

  @override
  AppState createState() => AppState();
}

class AppState extends State<App> {
  List<String> _items = ['1', '2', '3'];
  String _selected = '3';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(title: 'TestApp',
        home: Material(child: Column(
          children: <Widget>[
            RaisedButton(child: Text('Remove last Item'),onPressed: () => setState(() => _items.removeLast())),
            SearchableDropdown(items: _items.map((e) => DropdownMenuItem(value: e, child: Text(e))).toList(),
            value: _selected, onChanged: (e) => setState(() => _selected = e))
          ],
        )
      )
    );
  }
}

Hello @JChrist ,

It seems you solved your issue, is that right?

[JChrist]

Hi @lcuis, yes. I encountered some further issues that hindered the usage of this plugin (e.g. inline dialog breaking in web build) and also needed a way to load further values via api, so I've turned to a custom-made widget. Thanks!

Great if you found a solution. Cheers!
