Question

I am brand new to flutter and programming in general -so please bear with me-, so I am taking a course on udemy and I stumbled with this error (The constructor being called isn't a const constructor) This is the code :

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar:AppBar(
          title: Text('My First App'),
        ),
        body: Text('This is my default text'),
      ),
    );
  }
}

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('My First App'),
