Text

Text is component for displaying text. It supports style, basic touch handling, and inherits typographic styles from ancestor elements.

The Text is unique relative to layout: child elements use text layout (inline) rather than flexbox layout. This means that elements inside of a Text are not rectangles, as they wrap when reaching the edge of their container.

Unsupported React Native props: allowFontScaling (ios), suppressHighlighting (ios)

Props

NOTE: Text will transfer all other props to the rendered HTML element.

(web) accessibilityLabel: string

Defines the text available to assistive technologies upon interaction with the element. (This is implemented using aria-label.)

(web) accessibilityRole: oneOf(roles)

Allows assistive technologies to present and support interaction with the view in a manner that is consistent with user expectations for similar views of that type. For example, marking a touchable view with an accessibilityRole of button. (This is implemented using ARIA roles).

Note: Avoid changing accessibilityRole values over time or after user actions. Generally, accessibility APIs do not provide a means of notifying assistive technologies of a role value change.

(web) accessible: bool = true

When false, the text is hidden from assistive technologies. (This is implemented using aria-hidden.)

children: any

Child content.

numberOfLines: number

Truncates the text with an ellipsis after this many lines. Currently only supports 1.

onPress: function

This function is called on press.
