dash_chat producing an error when i tried to run the program

[Wizpna]

Thanks for the lovely plugin.

I downloaded the project and while trying to run the project on my computer, I received an error message and the project did not complete.

This is the error message

Can you provide some code and also which version of dash_chat, flutter version you are using so that I could investigate the problem.

[Wizpna]

Thanks for your feedback.

This is the code I added to my pubspec.yaml file:

dependencies:
dash_chat: ^1.0.4

While this code was what I added to my main.dart file.

import 'dart:async';

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final GlobalKey<DashChatState> _chatViewKey = GlobalKey<DashChatState>();

  final ChatUser user = ChatUser(

Hey, I don't think this is a problem with the package as I tried reproducing it but everything seems fine. What steps did you take that leads to this error. Are you running the example provided in the package if so there's no need to add dash_chat in dependencies

Thanks for your feedback.

This is the link to my chatbot repository https://github.com/Wizpna/chat_bot

When I run the project, I receive his error message:

Hey just checked you repository and everything works fine. I think this is something to with your flutter installation. Anyways, since this is not related to this package I am going to close this issue now.
