How do I tweak my Flutter Stack widget to not have bottom overflowing? - flutter

Question

[Update] : I got the solution, If you want the code, comment below or if you just want to know I've written it here :
The solution is to put the Cover Image and the Followers & Following inside a Column (as a single widget) and then put that Column and the Align (profile picture) both inside a Stack, then set the Fixed heightFactor.
So it would look something like this :
Stack(
children: <Widget>[
Column(
children: <Widget>[
Container(), //The Cover Photo
Container(
child: Card() //The Followers and Following Card
)
]
),
Align() //The Profile Picture having fixed heightFactor
]
)
This solution is working on all 4 Devices I have + 2 Android Emulators (2 have 16:9 ratio, 2 have 18:9 and 2 have 19:9 ratio).
The problem is following :
On my device, which is having 18:9 Aspect Ratio there is no Bottom Overflowing issue.
But on devices having 16:9 Aspect Ratio it's having this issue.
This happens only when I try to set heightFactor of Followers & Following Align widget.
I tried to tweak many things in Stack so I could overcome this, but couldn't achieve similar result. So, I'm stuck with this.
Also, as far as I know I can overlap only by using Stack widget. If there is any possible option, do say.
Here is my code :
Stack(
children: <Widget>[
Container(
width: MediaQuery.of(context).size.width,
height: 224.0,
margin: EdgeInsets.all(8.0),
decoration: BoxDecoration(
shape: BoxShape.rectangle,
borderRadius: BorderRadius.circular(8.0),
image: DecorationImage(
image: NetworkImage("https://www.eta.co.uk/wp-content/uploads/2012/09/Cycling-by-water-resized-min.jpg"),
fit: BoxFit.cover
)
),
),
Align(
heightFactor: 5.0,
child: Container(
alignment: Alignment.bottomCenter,
width: MediaQuery.of(context).size.width,
height: 96.0,
margin: EdgeInsets.all(8.0),
child: Card(
color: Colors.white,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(8.0)),
elevation: 0.0,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Text(
"Followers",
style: TextStyle(
fontFamily: "Nunito",
fontWeight: FontWeight.bold,
color: Colors.blue
),
),
Text(
"3000",
style: TextStyle(
fontFamily: "Nunito",
color: Colors.blue
),
),
],
),
Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Text(
"Following",
style: TextStyle(
fontFamily: "Nunito",
fontWeight: FontWeight.bold,
color: Colors.blue
),
),
Text(
"0",
style: TextStyle(
fontFamily: "Nunito",
color: Colors.blue
),
),
],
),
],
),
),
),
),
Align(
alignment: Alignment.bottomCenter,
heightFactor: 2.75,
child: Card(
color: Colors.transparent,
elevation: 0.0,
child: Container(
alignment: Alignment.bottomCenter,
width: 96.0,
height: 96.0,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: DecorationImage(
image: NetworkImage("https://cdn140.picsart.com/284302087007201.jpg?c256x256"),
fit: BoxFit.fill
),
border: Border.all(width: 4.0, color: Colors.blue)
),
),
),
),
],
),

Answer 1

You've provided the height of widget manually so it'll overflow on smaller screens. So you have to provide the height of widget depending upon the screen. You can use MediaQuery.of(context).size.height to get the height of the device.
And you can also multiply it with some number to get the height in percentage. For example, if you want 80% height of the screen then you can do MediaQuery.of(context).size.height * 80

Answer 2

The answer from #yashthakkar1173 is correct. That's one way of doing it. In addition to that I would say to his solution you can use
ConstrainedBox(
child: Card(),
constraints: BoxConstraints(
minHeight: 96.0,
maxHeight: 106.0,
))
What I observe is that you don't need the entire view to be in a Stack since it's just the top three widgets that overlap so I would wrap that stack in a column and set MainAxisSize to Min. I've done something similar, or you can set it to max so it'll always fill all the space left over.
