This attribute must be used with maxLines to take effect.

Default value: Infinity
NOTE
By default, text is automatically folded. If this attribute is specified, the text will not exceed the specified number of lines. If there is extra text, you can use textOverflow to specify how it is displayed.
lineHeight string | number | Resource Text line height. If the value is less than or equal to 0, the line height is not limited and the font size is adaptive. If the value of the number type, the unit fp is used.
