Flutter- wrapping text

Question

I want wrap text as text grows. I searched through and tried wrap with almost everything but still text stays one line and overflows from the screen. Does anyone know how to achieve this? Any help is highly appreciated!

Positioned(
    left: position.dx,
    top: position.dy,
    child: new Draggable(
      data: widget.index,
      onDragStarted: widget.setDragging,
      onDraggableCanceled: (velocity, offset) {
        setState(() {
          position = offset;
          widget.secondCallback(offset, widget.index);
          widget.endDragging();
        });
      },
      child: new GestureDetector(
        onTap: () {
          widget.callback(widget.caption, widget.index);
        },
        child: new Text(
            widget.caption.caption,
            style: new TextStyle(
              color: widget.caption.color,
              fontSize: widget.caption.fontSize,
            ),
          ),
      ),
      feedback: new Material(
        type: MaterialType.transparency,
        child: new Text(
          widget.caption.caption,
          style: new TextStyle(
              color: widget.caption.color,
              fontSize: widget.caption.fontSize),
          softWrap: true,
        ),
      ),
    ));

Answer 1

The Flexible does the trick

new Container(
       child: Row(
         children: <Widget>[
            Flexible(
               child: new Text("A looooooooooooooooooong text"))
                ],
        ));

This is the official doc https://flutter.dev/docs/development/ui/layout#lay-out-multiple-widgets-vertically-and-horizontally on how to arrange widgets.

Remember that Flexible and also Expanded, should only be used within a Column, Row or Flex, because of the Incorrect use of ParentDataWidget.

The solution is not the mere Flexible

Answer 2

In a project of mine I wrap Text instances around Containers. This particular code sample features two stacked Text objects.

Here's a code sample.

    //80% of screen width
    double c_width = MediaQuery.of(context).size.width*0.8;

    return new Container (
      padding: const EdgeInsets.all(16.0),
      width: c_width,
      child: new Column (
        children: <Widget>[
          new Text ("Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 Long text 1 ", textAlign: TextAlign.left),
          new Text ("Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2, Long Text 2", textAlign: TextAlign.left),
        ],
      ),
    );

[edit] Added a width constraint to the container

Answer 3

Using Ellipsis

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),

---

Using Fade

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),

---

Using Clip

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),

---

Note:

If you are using Text inside a Row, you can put above Text inside Expanded like:

Expanded(
  child: AboveText(),
)

Answer 4

Use Expanded

 Expanded(
            child: new Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: <Widget>[
                new Text(_name, style: Theme.of(context).textTheme.subhead),
                new Container(
                  margin: const EdgeInsets.only(top: 5.0),
                  child: new Text(text),
                ),
              ],
            ),

Answer 5

If it's a single text widget that you want to wrap, you can either use Flexible or Expanded widgets.

Expanded(
  child: Text('Some lengthy text for testing'),
)

or

Flexible(
  child: Text('Some lengthy text for testing'),
)

For multiple widgets, you may choose Wrap widget. For further details checkout this

Answer 6

Try Wrap widget to wrap text as text grows:

Example:

Wrap(
  direction: Axis.vertical, //Vertical || Horizontal
  children: <Widget>[
    Text(
      'Your Text',
      style: TextStyle(fontSize: 30),
    ),
    Text(
      'Your Text',
      style: TextStyle(fontSize: 30),
    ),
  ],
),

Answer 7

You Can Wrap your widget with Flexible Widget and than you can set property of Text using overflow property of Text Widget. you have to set TextOverflow.clip for example:-

Flexible
(child: new Text("This is Dummy Long Text",
 style: TextStyle(
 fontFamily: "Roboto",
 color: Colors.black,
 fontSize: 10.0,
 fontWeight: FontWeight.bold),
 overflow: TextOverflow.clip,),)

hope this help someone :)

Container(
  color: Color.fromRGBO(224, 251, 253, 1.0),
  child: ListTile(
    dense: true,
    title: Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      children: <Widget>[
        RichText(
          textAlign: TextAlign.left,
          softWrap: true,
          text: TextSpan(children: <TextSpan>
          [
            TextSpan(text: "hello: ",
                style: TextStyle(
                    color: Colors.black, fontWeight: FontWeight.bold)),
            TextSpan(text: "I hope this helps",
                style: TextStyle(color: Colors.black)),
          ]
          ),
        ),
      ],
    ),
  ),
),

Answer 9

You can use Flexible, in this case the person.name could be a long name (Labels and BlankSpace are custom classes that return widgets) :

new Column(
  crossAxisAlignment: CrossAxisAlignment.start,
  children: <Widget>[
   new Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: <Widget>[
        new Flexible(
            child: Labels.getTitle_2(person.name,
            color: StyleColors.COLOR_BLACK)),
        BlankSpace.column(3),
        Labels.getTitle_1(person.likes())
      ]),
    BlankSpace.row(3),
    Labels.getTitle_2(person.shortDescription),
  ],
)

Answer 10

Using SizedBox to hardcode the width, and softWrap to make new line of Text

SizedBox(
   width: 400,
   child: Text(
      "Really long text",
      softWrap: true,              
   ),
)

Answer 11

You can do it using the auto_size_text package:

 Container(
  child: ConstrainedBox(
    constraints: BoxConstraints(
      minWidth: 200.0,
      maxWidth: 200.0,
      minHeight: 50.0,
      maxHeight: 150.0,
    ),
    child: AutoSizeText(
      "Your Text",
      style: TextStyle(fontSize: 20.0),
    ),
  ),
);

Example:

You can further constrain the text by setting maxLines or specify presetFontSizes if you wish to restrict specific font sizes.

Answer 12

For Anybody who tried using an Expanded or Flexible widget and it didn't work, the trick is to set your text's maxLines property to a given value > 1. Example:

Row(children: [
                  Expanded(
                    child: Container(
                      color: Colors.red,
                      child: Text(
                        product.description!,
                        textAlign: TextAlign.left,

                       //Set MAXimum lines
                        maxLines: 5,
                        style: TextStyles.caption1TextStyle
                            .copyWith(fontSize: TextStyles.bodySize),
                      ),
                    ),
                  ),
]);

Answer 13

Pure Flutter. Multiple lines and auto fit inside container.

Widget text = LayoutBuilder(builder: (context, constraints) {
      return FittedBox(
          fit: BoxFit.scaleDown,
          child: ConstrainedBox(
              constraints: BoxConstraints(maxWidth: constraints.maxWidth),
              child: RichText(
                text: TextSpan(
                  text: 'your long text here',
                ),
                textAlign: TextAlign.center,
              )));
    });

Answer 14

Very simple solution for a simple instance, use the softWrap property of the Text Widget.

With softWrap enabled:

Answer 15

Expanded(
         child: Text(
           'It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.',
           style: TextStyle(fontSize: 58),
           softWrap: false,
           maxLines: 3,
         ),
       ),

Utilise Expanded widget to set TextOverflow.visible

for those who want this, thankks

Answer 16

Wrap Text with the FittedBox widget:

Container(
        height: 40,
        width: 40,
        color: Colors.blue,
        child: const FittedBox(
          fit: BoxFit.fill,
          child: Text('Hello world!', style: TextStyle(fontSize: 20)),
        ));

Answer 17

wrapping text flutter

 Container(
            padding: EdgeInsets.all(20.0),
            child: Text(
              'This is a long text that needs to be wrapped to the next line because it cannot fit within the available space.',
              style: TextStyle(fontSize: 16.0),
              maxLines: 2, // Limit the text to 2 lines
              overflow: TextOverflow.ellipsis, // Use ellipsis (...) for overflow

            ),
          ),
