Description
On Android, Text elements that have adjustsFontSizeToFit={true} do not have their font size adjusted when the height of a parent element is changed. This works as desired on iOS. This seems to be a defect in the excellent PR #26389 by @janicduplessis.

Steps To Reproduce
- Run the following app:
import * as React from 'react';
import { Text, View, StyleSheet, Button } from 'react-native';
export default class App extends React.Component {
state = {
rowHeight: 60,
};
render() {
return (
<View style={styles.container}>
<View style={[styles.row, {height:this.state.rowHeight}]}>
<Text adjustsFontSizeToFit numberOfLines={1} style={styles.paragraph}>
Text text text text text text
</Text>
</View>
<Text>{this.state.version}</Text>
<View style={styles.button}>
<Button onPress={() => this.setState({rowHeight: 10})} title="Set row height to 10"/>
</View>
<View style={styles.button}>
<Button onPress={() => this.setState({rowHeight: 60})} title="Set row height to 60"/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
justifyContent: 'center',
paddingTop: 100,
},
row: {
backgroundColor: 'lightblue',
marginBottom: 20,
},
button: {
margin: 10
},
paragraph: {
fontSize: 100,
fontWeight: 'bold',
textAlign: 'center',
backgroundColor: "yellow"
},
});
- Press the button labeled "Set row height to 10". Observe that on iOS the text's font size is reduced but is unchanged on Android.
Expected Results
The font size of the Text element should be changed when the height of a parent element is changed on Android, consistent with iOS.
