Description

The properties mentioned don't seem to have any affect on TextInputs, not only that but I also get a weird initial height which changes as soon as I enter a key. There are issues with this on both iOS and Android but they are slightly different.

iOS

Android

Reproducible Demo

react-native init reproduce

Replace App.js with:

 /**
 * @format
 * @flow
 */

import React, {Component} from 'react';
import {TextInput} from 'react-native';
type Props = {};
export default class App extends Component<Props> {
    render() {
        return (
                <TextInput
                    multiline={true}
                    numberOfLines={2}
                    editable={true}
                    style={{
                        margin:50,
                        lineHeight: 100,
                        borderWidth: 1,
                        marginBottom: 10
                    }}
                />
        );
    }
}
