can't wrap my long text inside a card in flutter - flutter

Question

I'm trying to put a text inside a card and make the card a bit flexible whenever there is a long text it goes to the next line automatically and the card gets langer
Widget ServiceCard (BuildContext context,double price){
return Container(
height: 100,
margin: EdgeInsets.only(top: 12,right: 8,left: 8),
width: MediaQuery.of(context).size.width,
child: Card(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(16)
),
color: Colors.white,
elevation: 8,
child: Stack(
children: <Widget>[
Positioned(
top: 8,
left: 8,
child: Text("\$$price"),
),
Positioned(
right: 8,
top: 8,
child: Container(
// height: 70,
child: Column(
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
Container(
alignment: Alignment.topRight,
child: Text("غسيل شعر",style: TextStyle(fontSize: 16),)
),
Opacity(
opacity:0.7,
child: Text(
"يتم تصفيف الشعر وغسيل يتم تصفيف الشعر وغسيل يتم تصفيف الشعر وغسيل"
)
),
],
),
),
)
],
),
),
);
}
with this code im having the text goes over the card and not going to the next line and even the card is in a constent heghit not wrapped

To make Text wrap on overflow, ideally it has to be sized to full width and maxLines property must be set to null.
However, I can see that you have encountered an "edge-case" - all your text is placed in a Stack widget, which does not fit its children in width by default.
To solve this, change your Positioned(...) widget to Positioned.fill.
e.g.
Positioned.fill(
right: 8,
top: 8,
child: Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch, // You might want to use this, too - this stretches all children in width by default
children: <Widget>[
Container(
alignment: Alignment.topRight,
child: Text("غسيل شعر", style: TextStyle(fontSize: 16))
),
Opacity(
opacity: 0.7,
child: Text(
"يتم تصفيف الشعر وغسيل يتم تصفيف الشعر وغسيل يتم تصفيف الشعر وغسيل",
textDirection: TextDirection.rtl, // I assume this would be helpful too, if your language reads from right to left.
)
),
],
),
),
)
Let me know if this helped.
