Error Caused

```
The following assertion was thrown building IconButton(Icon, padding: EdgeInsets.all(8.0), dirty):
No Material widget found.
IconButton widgets require a Material widget ancestor.
In material design, most widgets are conceptually "printed" on a sheet of material. In Flutter's
material library, that material is represented by the Material widget. It is the Material widget
that renders ink splashes, for instance. Because of this, many material library widgets require that
there be a Material widget in the tree above them.
To introduce a Material widget, you can either directly include one, or use a widget that contains
Material itself, such as a Card, Dialog, Drawer, or Scaffold.
The specific widget that could not find a Material ancestor was:
IconButton
The ancestors of this widget were:
...
Padding
DecoratedBox
Container
FadeTransition
AnimatedOpacity
...

The relevant error-causing widget was:
IconButton
IconButton:file:///C:/Users/91797/Documents/flutter/.pub-cache/hosted/pub.dartlang.org/chewie-1.2.2/lib/src/center_play_button.dart:38:22

```
