try {
return Scaffold(
body: StreamBuilder(
stream: mystreamofallvideos,
builder: (context, snapshot) {
if (snapshot.hasData &&
snapshot.connectionState != ConnectionState.waiting) {
return PageView.builder(
itemCount: snapshot.data.docs.length,
controller:
PageController(initialPage: 0, viewportFraction: 1),
scrollDirection: Axis.vertical,
itemBuilder: (context, index) {
DocumentSnapshot videos = snapshot.data.docs[index];
return Stack(children: [
Videoplayeritem(widget.videoid),
Column(children: [
Align(
alignment: Alignment.bottomLeft,
child: Container(
height: 100,
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
children: [
IconButton(
icon: Icon(
Icons.close,
color: Colors.white,
size: 35,
),
onPressed: () {
Navigator.of(context).pop();

Container(

Answer 1

Wrap it in an align and add a padding to the bottom:
Align(
alignment: Alignment.bottomRight,
child: Container(
height: 40,
padding: const EdgeInsets.only(bottom: 16),
child: OutlinedButton(
onPressed: () {},
child: Text('mybutton'),
),
)

Answer 2

you can wrap your container with either Positioned or Align widgets
like :
Positioned(
top: 0.0,
left: 0.0,
child: Icon(Icons.message,
size: 128.0, color: Colors.greenAccent[400]), //Icon
),
