Text class

A run of text with a single style.

The Text widget displays a string of text with single style. The string might break across multiple lines or might all be displayed on the same line depending on the layout constraints.

The style argument is optional. When omitted, the text will use the style from the closest enclosing DefaultTextStyle. If the given style's TextStyle.inherit property is true (the default), the given style will be merged with the closest enclosing DefaultTextStyle. This merging behavior is useful, for example, to make the text bold while using the default font family and size.

Text(
  'Hello, $_name! How are you?',
  textAlign: TextAlign.center,
  overflow: TextOverflow.ellipsis,
  style: TextStyle(fontWeight: FontWeight.bold),
)

Using the Text.rich constructor, the Text widget can display a paragraph with differently styled TextSpans. The sample that follows displays "Hello beautiful world" with different styles for each word.

const Text.rich(
  TextSpan(
    text: 'Hello', // default text style
    children: <TextSpan>[
      TextSpan(text: ' beautiful ', style: TextStyle(fontStyle: FontStyle.italic)),
      TextSpan(text: 'world', style: TextStyle(fontWeight: FontWeight.bold)),
    ],
  ),
)

Interactivity

To make Text react to touch events, wrap it in a GestureDetector widget with a GestureDetector.onTap handler.

In a material design application, consider using a FlatButton instead, or if that isn't appropriate, at least using an InkWell instead of GestureDetector.

To make sections of the text interactive, use RichText and specify a TapGestureRecognizer as the TextSpan.recognizer of the relevant part of the text.

Constructors

Text(String data, { Key key, TextStyle style, StrutStyle strutStyle, TextAlign textAlign, TextDirection textDirection, Locale locale, bool softWrap, TextOverflow overflow, double textScaleFactor, int maxLines, String semanticsLabel })
Creates a text widget. [...]
const
Text.rich(TextSpan textSpan, { Key key, TextStyle style, StrutStyle strutStyle, TextAlign textAlign, TextDirection textDirection, Locale locale, bool softWrap, TextOverflow overflow, double textScaleFactor, int maxLines, String semanticsLabel })
Creates a text widget with a TextSpan. [...]
const

Properties

data String
The text to display. [...]
final
locale Locale
Used to select a font when the same Unicode character can be rendered differently, depending on the locale. [...]
final
maxLines int
An optional maximum number of lines for the text to span, wrapping if necessary. If the text exceeds the given number of lines, it will be truncated according to overflow. [...]
final
overflow TextOverflow
How visual overflow should be handled.
final
semanticsLabel String
An alternative semantics label for this text. [...]
final
softWrap bool
Whether the text should break at soft line breaks. [...]
final
strutStyle StrutStyle
The strut style to use. Strut style defines the strut, which sets minimum vertical layout metrics. [...]
final
style TextStyle
If non-null, the style to use for this text. [...]
final
textAlign TextAlign
How the text should be aligned horizontally.
final
textDirection TextDirection
The directionality of the text. [...]
final
textScaleFactor double
The number of font pixels for each logical pixel. [...]
final
textSpan TextSpan
The text to display as a TextSpan. [...]
final
hashCode int
The hash code for this object. [...]
read-only, inherited
key Key
Controls how one widget replaces another widget in the tree. [...]
final, inherited
runtimeType Type
A representation of the runtime type of the object.
