removing space

[shinriyo]

Hello.
Thank you for such a wonderful sample.

However.., I want to remove the space.
is it possible?

import 'package:flutter/material.dart';

import 'fancy_tab_bar.dart';
import 'tab_item.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(
        primarySwatch: Colors.deepPurple,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key}) : super(key: key);

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> with TickerProviderStateMixin {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.grey.shade200,
      appBar: AppBar(
        backgroundColor: PURPLE,
        title: Text("Tab Bar Animation"),
      ),
      bottomNavigationBar: FancyTabBar(),
      body: Center(
//        child: Column(
//          mainAxisAlignment: MainAxisAlignment.center,
//          children: <Widget>[
//            Text(
//              'You have pushed the button this many times:',
//            ),
//          ],
//        ),
        // I added for reveal space
        child: Container(color: Colors.red),
      ),
    );
  }
}
