TextInput multiline text does not appear centered if only one line

[paperskyline]

Current behaviour

When TextInput has multiline prop, the text is vertically aligned towards the top if the input field contains only one line (screenshot 1). If the text is longer and shows two or more lines, then everything appears fine and the content is centered accordingly. (screenshot 2). You can see from the image below where i marked the spacings in red

Expected behaviour

Text Should be centered inside the the TextInput even if it contains text which takes up only a single line.

How to reproduce?

<TextInput multiline mode='outlined' style={{ paddingRight: 10, paddingLeft: 10, fontSize: 16, color: 'black', backgroundColor: 'grey' }} dense />

Preview

What have you tried so far?

textAlignVertical="center" did not work. Couldn't find other issues similar to this.

Hey, thanks for Commenting!
In My Opinion, Your issue could be solved by adjusting the Height of your text input and then Passing the textAlignVertical="center" prop
This Should Work:
<TextInput multiline mode="outlined" style={{ paddingRight: 10, paddingLeft: 10, fontSize: 16, color: "black", backgroundColor: "grey", height: 40, }} dense textAlignVertical="center" />
If you also Want to Check previous lines, you Could use a ScrollView.
Hope this Helps!

If you set the height, you are pretty much taking away the point of multiline.
as for using scrollview to view the previous text, the UX is horrible.

The TextInput from react-native has the exact same issue, so I don't think it's specific to react-native-paper

Adding the following would make it work properly

       contentStyle={{
              minHeight: 48,
              textAlignVertical: 'center',
            }}

@andyto textAlignVertical is only for android.

I ended up making a component that adjusts paddingTop in the TextInput style based on whether it currently has a single line or multiple lines, which I detect using onLayout to track the height of the component. It was a lot of work just to make the text centered...

Encountered the same issue, ended up doing the following:
Do not specify the height of the TextInput explicitly, instead wrap your TextInput inside a Pressable element, and center it vertically. You can propagate the press events from the Pressable element and focus the TextInput.

import React, { useRef } from 'react';
import { Pressable, TextInput, View } from 'react-native';

const YourComponent = () => {
  const textInputRef = useRef(null);
  const [message, setMessage] = React.useState<string>("")

  const handlePress = () => {
    if (textInputRef.current) {
      textInputRef.current.focus();
    }
  };

  return (
    <Pressable onPress={handlePress} style={styles.textInputView}>
      <TextInput
        ref={textInputRef}
        style={styles.messageInput}
        placeholder="Type your message..."
        placeholderTextColor="#999"
        value={message}
        onChangeText={setMessage}
        selectionColor="#1D1B1D"
        multiline
      />
    </Pressable>
  );
};


const styles = StyleSheet.create({
  textInputView: {
    minHeight: 40,
    justifyContent: 'center',
    paddingBottom: 8,
    flex: 1,
  },
  messageInput: {
    color: '#1D1B1D',
    fontSize: 15,
    lineHeight: 20,
    fontStyle: 'normal',
    letterSpacing: -0.075,
    paddingLeft: 10,
  }
});

This the best I could come up with: multiline={value.length > 35}; dynamically setting multiline based off number of characters.

Very bad approach
