Description
Description
Nesting View inside Text adds lineHeight's marginBottom to View and when we add Text inside that View it doesn't gets aligned properly.

Steps To Reproduce
- Setup a CRNA or Expo app.
- Replace the code in App.js with -
import { StatusBar } from "expo-status-bar";
import React from "react";
import { StyleSheet, Text, View } from "react-native";
export default function App() {
return (
<View style={styles.container}>
<Text style={styles.outsideText}>
Outside Text{" "}
<View style={styles.insideView}>
<Text>Inside Text</Text>
</View>
</Text>
<StatusBar style="auto" />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#fff",
alignItems: "center",
justifyContent: "center",
},
outsideText: {
backgroundColor: "#cecece",
},
insideView: {
backgroundColor: "#fcc9",
},
});
- Start your App on iOS or Android with
yarn iosoryarn android.
Expected Results
The text should be in the same line aligned vertically. Like it looks when we run this example on the Web.

Research direction
Reproduce the alignment issue from the App.js example in the issue, using the linked Snack or a CRNA/Expo app and running yarn ios or yarn android. Trace how the nested View inside Text handles lineHeight and vertical layout on iOS and Android. Done means the nested Inside Text appears on the same line and is vertically aligned with Outside Text.
