TextOverFlow Flutter - flutter

Question

I have a certain Text widget , when it overflows I have 3 options. Either fade ,visible, ellipsis or clip. But I don't want to choose between them . I want if a text has overflow then don't show the text.
Edit :
I'm working on a code clone to this design
Assuming that the textStyle is unknown.
How could I achieve that?
Code:
class SwipeNavigationBar extends StatefulWidget {
final Widget child;
SwipeNavigationBar({this.child});
#override
_SwipeNavigationBarState createState() => _SwipeNavigationBarState();
}
class _SwipeNavigationBarState extends State<SwipeNavigationBar> {
#override
Widget build(BuildContext context) {
return Consumer<Controller>(
builder: (_, _bloc, __) {
return SafeArea(
child: AnimatedContainer(
duration: Duration(seconds: 01),
color: Colors.white,
curve: Curves.easeIn,
height: !_bloc.x ? 50 : 200,
child: Row(
children: [
Column(
verticalDirection: VerticalDirection.up,
children: [
Expanded(child: Icon(Icons.dashboard)),
Expanded(
child: RotatedBox(
quarterTurns: -45,
child: Text(
'data',
softWrap: false,
style: TextStyle(
textBaseline: TextBaseline.alphabetic
),
),
),
),
],
)
],
),
),
);
},
);
}
}

Answer 1

To mimic the design you might want to look into using the Stack widget. However, to answer your question, you'd want to set softWrap to false.
Align(
alignment: Alignment.topLeft,
child: SizedBox(
width: 100,
child: Text(
'Some text we want to overflow',
softWrap: false,
),
),
)
softWrap is really the key here. Although, I added the Align and SizedBox widgets to allow this to be used anywhere, regardless of what parent widget you are using (since some widgets set tight constraints on their children and will override their children's size preference).

Edit: 5/6/2020
With the release of Flutter v1.17 you now have access to a new Widget called NavigationRail which may help you with the design you're looking for.

Answer 2

Use ternary operator to check the length of the text that you are passing to the Text widget and based on that pass the text itself or an empty string.
String yourText;
int desiredLengthToShow = 10; //Change this according to you.
...
Text(
child: yourText.length > desiredLengthToShow ? "" : yourText,
);
