Flutter Multiline for text

问题

All I need is my text to be multi-line. Am giving the property of maxLines but its still getting RenderFlex overflowed error to the right as the next is not going to 2nd line,

      Align( alignment: Alignment.bottomCenter,
      child: new ButtonBar(
        alignment: MainAxisAlignment.center,
        children: <Widget>[
          Padding(
            padding: EdgeInsets.all(20.0),
            child: new Text(
              "This is a very bigggggggg text !!!",textDirection: TextDirection.ltr,
              style: new TextStyle(fontSize: 20.0, color: Colors.white),
              maxLines: 2,
            ),
          )
        ],
      ),
    )

Make sure that the parent widget limits your text's width, and then use overflow and maxlines, e.g.:

Container(
  width: 150,
  child: Text(
    "This text is very very very very very very very very very very very very very very very very very very very very very very very very very long",
    overflow: TextOverflow.ellipsis,
    maxLines: 5,
  ),
),

Just wrap your text widget with Expended as below

    Expanded(
      child: Text("data", maxLines: 4,
        overflow: TextOverflow.ellipsis,
        textDirection: TextDirection.rtl,
        textAlign: TextAlign.justify,),
    ),

I think you forgot to add overflow type.

You can use something like this:

Text(
     "TOP ADDED",
     textAlign: TextAlign.justify,
     overflow: TextOverflow.ellipsis,
     style: TextStyle(fontSize: 18.0),
     maxLines: 2,)

try this:

Expanded(            
    child: Text(
      'a long text,
      overflow: TextOverflow.clip,
    ),
),

in my implementation I put this inside a row and surrounded it with sized boxes on each side so that I have some space between my elements, why using expanded you may ask, well it's used to take as much space as possible so the text would look good in portrait or landscape mode.

and here is a full example on how to make it even react vertically not just horizontally:

Card(
  child: InkWell(
    onTap: (){},
    child: Padding(
      padding: const EdgeInsets.all(8.0),
      child: Row(
        children: <Widget>[
          SizedBox(
            height: 70, // default\minimum height
          ),
          Container(
            height: 44,
            width: 44,
            decoration: BoxDecoration(
                color: Colors.blue,
                borderRadius: BorderRadius.all(Radius.circular(22))),
          ),
          SizedBox(
            width: 15,
          ),
          Expanded(
            child: Text(
              'the very long title',
              overflow: TextOverflow.clip,
            ),
          ),
          SizedBox(
            width: 10,
          ),
          Text(
            'value', //some other text in the end of the card or maybe an icon instead
          ),
          SizedBox(
            width: 30,
          ),
        ],
      ),
    ),
  ),
)

Maybe try using TextField:

new TextField(
  keyboardType: TextInputType.multiline,
  maxLines: 2,
)
