Error: Entrypoint doesn't contain a main function Flutter

Question

I got an error Error: Entrypoint doesn't contain a main function Flutter, I tried to restart android studio but it did not work

Answer 1

Depends on what the program is support to do. There should be a main class that is initiated. As an example:

    import 'package:flutter/material.dart';
    import 'package:english_words/english_words.dart';
    void main() => runApp(MyApp()); // initiate MyApp as  StatelessWidget

    // Main class
    class MyApp extends StatelessWidget {
      // creating main screen and building list of wordpairs
      @override
