MongolText class

A run of vertical text with a single style.

The MongolText widget displays a string of vertical 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.

{@tool snippet}

This example shows how to display text using the MongolText widget with the overflow set to TextOverflow.ellipsis.

If the text is shorter than the available space, it is displayed in full without an ellipsis.

If the text overflows, the Text widget displays an ellipsis to trim the overflowing text.

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

{@end-tool}

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

const MongolText.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)),
    ],
  ),
)
