What should I pass in MyApp in main?-CodePudding

void main()

{

runApp(MyApp());

}

class MyApp extends StatelessWidget {

final StreamChatClient client;

MyApp(this.client);

}

CodePudding user response：

Yes this will throw an error because you are expecting a parameter but haven't passed any argument in it. To solve this you can make your parameter optional and StreamChatClient nullable like below

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

class MyApp extends StatelessWidget {

  final StreamChatClient? client;

  MyApp({this.client});

}

CodePudding user response：

I think it should be like this , because you are creating a constructor and it should be wrapped inside a curly braces. And the required part may be optional for the user to user.

import 'package:flutter/material.dart';
void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
final StreamChatClient client;

MyApp({required this.client});
