Description

Disallow raw text outside <Text> components in React Native.

In React Native, every string rendered in the UI must be wrapped in a <Text> component. Rendering text directly inside containers such as <View> throws at runtime on native platforms.

By default, the following element names are treated as valid text containers: Text, TSpan, StyledText, and Animated.Text. Additional components can be whitelisted through the skip option.

Examples

Invalid

1
<View>some text</View>
