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.

Container(
  width: 100,
  decoration: BoxDecoration(border: Border.all()),
  child: Text(overflow: TextOverflow.ellipsis, 'Hello $_name, how are you?'))

Text(
  overflow: TextOverflow.fade,
  maxLines: 1,
  'Hello $_name, how are you?')

// ...

Text(
  overflow: TextOverflow.fade,
  softWrap: false,
  'Hello $_name, how are you?')

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 TextButton 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.

Selection

Text is not selectable by default. To make a Text selectable, one can wrap a subtree with a SelectionArea widget. To exclude a part of a subtree under SelectionArea from selection, once can also wrap that part of the subtree with SelectionContainer.disabled.
