'emoji picker flutter search function

Has anyone used the emoji_picker_flutter package and used the search function provided? Trying to get it all to work and it's not working. Any help would be great, below is my code. I want the text input to be a search field instead and when clicking in the search field the emojis disappear until you search. I have been able to achieve that by assigning a set state and a bool there to display or not display the emojis, I just haven't been able to implement the search function with this package.

// Search for related emoticons based on keywords --- this is the given info to use to get the search to work ...

final filterEmojiEntities = await EmojiPickerUtils().searchEmoji("face");

import 'dart:io';

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

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

/// Example for EmojiPickerFlutter
class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final TextEditingController _controller = TextEditingController();
  bool emojiShowing = false;

  _onEmojiSelected(Emoji emoji) {
    _controller
      ..text += emoji.emoji
      ..selection = TextSelection.fromPosition(
          TextPosition(offset: _controller.text.length));
  }

  _onBackspacePressed() {
    _controller
      ..text = _controller.text.characters.skipLast(1).toString()
      ..selection = TextSelection.fromPosition(
          TextPosition(offset: _controller.text.length));
  }

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(

 List? filterEmojiEntities;   
 Material(
                  color: Colors.transparent,
                  child: IconButton(
                      onPressed: () async {
                        filterEmojiEntities = await EmojiPickerUtils()
                            .searchEmoji(_controller.text);
                       
                      }, 
                      icon: const Icon(
                        Icons.send,
                        color: Colors.white,
                      )),
                )

In the below screenshot, you can see the value of "_controller.text" is the same which I typed in textfield of simulator:

And here you can see the list of grinning face emojis:

Now you just need to use these list items where ever you want
