Can not fit image and text in AppBar Flutter - flutter

Question

I want to place image and text into appbar, but it seems that i cant fit all i want into appbar.
I have this code:
return DefaultTabController(
length: 2,
child: Scaffold(
appBar: AppBar(
title:Column(
children: [
Container(
child: Image.asset(
'assets/vecteezy_circle-abstract_1191814.png',
fit: BoxFit.scaleDown,
height: 100,
),
),
Container(
padding: const EdgeInsets.only(top: 15),
child: Text('Text'))
],
),
bottom: TabBar(
tabs: [Tab(text: 'tab 1'), Tab(text: 'tab 2')],
),
),
body: TabBarView(children: [
Text("o"),
Text("kk"),
]),
));
}
and I have such result :

You need to use CustomScrollView with SliverAppBar
look at this example from Flutter Dev
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
MyApp({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
final title = 'Floating App Bar';
return MaterialApp(
title: title,
home: Scaffold(
// No appbar provided to the Scaffold, only a body with a
// CustomScrollView.
body: CustomScrollView(
slivers: <Widget>[
// Add the app bar to the CustomScrollView.
SliverAppBar(
// Provide a standard title.
title: Text(title),
// Allows the user to reveal the app bar if they begin scrolling
// back up the list of items.
floating: true,
// Display a placeholder widget to visualize the shrinking size.
flexibleSpace: Placeholder(),
// Make the initial height of the SliverAppBar larger than normal.
expandedHeight: 200,
),
// Next, create a SliverList
SliverList(
// Use a delegate to build items as they're scrolled on screen.
delegate: SliverChildBuilderDelegate(
// The builder function returns a ListTile with a title that
// displays the index of the current item.
(context, index) => ListTile(title: Text('Item #$index')),
// Builds 1000 ListTiles
childCount: 1000,
),
),
],
),
),
);
}
}
