Flutter Text Widget

In Flutter the Text widget is used to display single or multi-line string in UI. If we don’t specify any styling in a text widget, it will use DefaultTextStyle.

In this tutorial, you will learn how to efficiently use the Text widget and how to style the text widget using the style property. Here a simple example of Text Widget.

Text("This is a Text Widget"),


When we run this code, we will get output like this,

    double textScaleFactor,  
    int maxLines,

  • TextAlign: It is used to control the text horizontally.
  • TextDirection: It is used to control The direction in which text flows.
  • TextOverflow: It is used to handle the overflow text.
  • softWrap: if enough space is available it shows all content, otherwise it does not show all content.
  • maxLines: It is used to determine the maximum number of lines displayed in the text widget.
  • TextWidthBasis: It defines how to measure the width of the rendered text.
  • TextHeightBehavior: It defines how the paragraph will apply TextStyle.height to the ascent of the first line and descent of the last line.
  • style: It is the most popular property of the Text Widget. It is used to customize the fontSize, fontWeight, color, etc.

Flutter TextStyle Property

Flutter Text Widget Line Break

If you have multiline text, to break the text at specific word use \n escape character. For example,

Text("This is a Text Widget \n by Code With Flutter"),
Flutter Text Widget
Flutter Text Line Break

Flutter Text Overflow

Sometimes text overflowed because of not specifying the width of the widget. To solve the text-overflow problem, use the overflow property. Here an example of overflow property.

Text(
"When using long text, sometimes text overflowed some pixels. To sole this",
overflow: TextOverflow.ellipsis,
),

Using the overflow: TextOverflow.ellipsis property, it will append three dots at end of the text. Here is an output of the code.

)

            fontStyle: FontStyle.italic,
            letterSpacing: 8,
            wordSpacing: 10,
              shadows: [
                Shadow(color: Colors.blueAccent, offset: Offset(2,1), blurRadius:7)
              ]
