Flutter TikTokStyleFullPageScroller() not working on empty (non content) screen - flutter

Question

I am new to Flutter and trying to add slide functions to videos. It seems to be working as expected but only if slide by tapping on content area. In other words if tapped on video to slide it doesn't work.
Package:
tiktoklikescroller: ^0.1.1
import 'package:tiktoklikescroller/tiktoklikescroller.dart';
Here is my code:
#override
Widget build(BuildContext context) {
final List<Color> colors = <Color>[Colors.red, Colors.blue, Colors.yellow];
return Expanded(
child: TikTokStyleFullPageScroller(
contentSize: colors.length,
swipeThreshold: 0.2,
swipeVelocityThreshold: 2000,
animationDuration: const Duration(milliseconds: 300),
builder: (BuildContext context, int index) {
return Row(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
VideoDescription(),
ActionToolbar(),
],
);
},
),
);
}
Video Description
class VideoDescription extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Expanded(
child: Align(
alignment: Alignment.bottomLeft,
child: Container(
height: 70.0,
padding: EdgeInsets.only(left: 20.0),
margin: EdgeInsets.only(bottom: 160.0),
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text('Title', style: TextStyle(fontWeight: FontWeight.bold),),
],
),
),
),
);
}
}
Action Toolbar
#override
Widget build(BuildContext context) {
return Container(
width: 100.0,
margin: EdgeInsets.only(bottom: 25.0),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
_getMusicPlayerAction(),
],
),
);
}
Please help.

Answer 1

I wrapped VideoDescription() and ActionToolbar() inside a container and gave it a transparent color.
#override
Widget build(BuildContext context) {
final List<Color> colors = <Color>[Colors.red,
Colors.blue, Colors.yellow];
return Expanded(
child: TikTokStyleFullPageScroller(
contentSize: colors.length,
swipeThreshold: 0.2,
swipeVelocityThreshold: 2000,
animationDuration: const Duration(milliseconds: 300),
builder: (BuildContext context, int index) {
return Container(
color: Colors.transparent,
Row(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
VideoDescription(),
ActionToolbar(),
],
),
);
},
),
);
}
