title: Can't initialize firebaseapp in flutter
body: <p>Why would it not work? When I remove Firebase.initializeApp(); it works just fine. Everywhere I put it, it still doesn't work. I've tried to add it to every different place but it still didn't do anything.</p>
  <pre><code>import 'package:firebase_storage/firebase_storage.dart';
  import 'package:flutter/material.dart';
  import 'package:cloud_firestore/cloud_firestore.dart';
  import 'package:firebase_core/firebase_core.dart';
  
  
  void main() =&gt; runApp(MaterialApp(
    Firebase.initializeApp();
        home: Scaffold(
          appBar: AppBar(
            title: Text('123'),
            centerTitle: true,
            backgroundColor: Colors.red[600],
          ),
          body: Center(
            child: Text(
              'hello mars!',
              style: TextStyle(
                fontSize: 20.0,
                fontWeight: FontWeight.bold,
                letterSpacing: 2.0,
                color: Colors.grey[600],
              ),
            ),
          ),
          floatingActionButton: FloatingActionButton(
            onPressed: () {},
            child: Text('click'),
            backgroundColor: Colors.red[600],
