Library to help managing keyboard interaction in form
npm install @appandflow/react-native-magic-scrollApp & Flow is a Montreal-based React Native engineering and consulting studio. We partner with the world’s top companies and are recommended by Expo. Need a hand? Let’s build together.

The goal of the library is to seamlessly and precisely handle your keyboard, scrollview and inputs when interacting with forms. While other solutions offer plug-and-play functionalities, we wanted to have something more precise and with more flexibility so that it can be used in any situation.
We recreated two flows from popular apps to showcase our library in action.
The demo app code is available here.

``sh`
yarn add @appandflow/react-native-magic-scroll
`sh`
npm i @appandflow/react-native-magic-scroll
To use our library, you will need to install these two dependencies into your project.
1) React Native Reanimated
`sh`
npx expo install react-native-reanimated
Learn more about this dependency here.
2) SafeAreaContext
`sh`
npx expo install react-native-safe-area-context
Learn more about this dependency here.
On Android, make sure to set android:windowSoftInputMode in your AndroidManifest.xml to pan

// app.json
"android": {
...rest,
"softwareKeyboardLayoutMode": "pan"
}
Wrap your screen within our ScrollView.
`tsx
import { MagicScroll } from '@appandflow/react-native-magic-scroll';
// rest of your imports
const YourScreen = () => {
return
};
export default YourScreen;
`
You then use our TextInputs for the form itself, that you place inside the MagicScroll.ScrollView. Easily "chain" your inputs (so that the return keyboard button hops to the next desired input) by using the MagicScroll.TextInput name and chainTo props, like so:
`tsx
import { MagicScroll } from '@appandflow/react-native-magic-scroll';
// rest of your imports
const textInputStyle = {
height: 50,
backgroundColor: '#ddd',
borderRadius: 10,
marginTop: 8,
};
const YourScreen = () => {
return (
prop
name="email"
// This is where you can design your a custom label above the input
renderTop={() =>
// This is where you can design your custom label below the input
renderBottom={() =>
// This is the function that will make the text input named "password" focused when pressing the Enter or Return key on the device's keyboard
chainTo="password"
textInputProps={{
style: textInputStyle,
}}
/>
renderTop={() =>
textInputProps={{
secureTextEntry: true,
style: textInputStyle,
}}
/>
);
};
`
You can also use the renderInput function and use any kind of input
`tsx
import { MagicScroll } from '@appandflow/react-native-magic-scroll';
// rest of your imports
const textInputStyle = {
height: 50,
backgroundColor: '#ddd',
borderRadius: 10,
marginTop: 8,
};
const YourAwesomeInput = ({
label,
...props
}: TextInputProps & { label: string }) => {
return (
);
};
const YourScreen = () => {
return (
prop
name="email"
// This is where you can pass your input. You need to spread the prop object. Make sure it is the last prop
renderInput={(magicProps) => (
)}
// This is the function that will make the text input named "password" focused when pressing the Enter or Return key on the device's keyboard
chainTo="password"
textInputProps={{
style: textInputStyle,
}}
/>
renderTop={() =>
textInputProps={{
secureTextEntry: true,
style: textInputStyle,
}}
/>
);
};
`
As mentioned in the introduction, the drawbacks of a plug-and-play library are its limitations when deviating from standard functionality. That's precisely why our library allows for customization, enabling you to tailor its usage to suit your specific needs and use cases.
It's a great idea to wrap our MagicScroll.TextInput within your own for re-usability!
Here's an example
`tsx
import { MagicScroll } from '@appandflow/react-native-magic-scroll';
// rest of your imports
interface Props {
label?: string;
isPassword?: boolean;
name?: string;
description?: string;
chainTo?: string;
}
const YourCustomInput = (props: Props) => {
return (
chainTo={props.chainTo}
renderTop={() =>
renderBottom={() =>
textInputProps={{
secureTextEntry: props.isPassword,
style: {
height: 50,
backgroundColor: '#ddd',
borderRadius: 10,
marginTop: 8,
},
}}
/>
);
};
`
All of these props are optional. It is, however, recommended to use them to get the most out of the library.
