react-native-autogrow-textinput
A helper component meant to be used as a drop-in replacement for RN TextInput to allow automatic expanding of a multi-line text input according to the number of lines.
Installation
Install using npm:
npm i react-native-autogrow-textinput --save
Native side installation
To fix the issue with the height not being set for initial values (or with other cases where the input is not set by the user typing using the keyboard) you need to add the libAutoGrowTextInput to your project. After performing npm install, locate AutoGrowTextInput.xcodeproj in YOUR_PROJECT/node_modules/react-native-autogrow-textinput/ios and drag it to your own project, then in your target's general settings, add it to the "Linked Frameworks and Libraries".
How To Use
Import the new component:
import {AutoGrowingTextInput} from 'react-native-autogrow-textinput';
Now use it as you would normally do with a ScrollView to wrap arround TextInput components:
<AutoGrowingTextInput style={styles.textInput} placeholder={'Your Message'} />
Example Project

In the example folder, perform npm install and then run it from the Xcode project.
