@dioncodes/react-native-layout-margins v1.3.3

react-native-layout-margins

A simple react native module for views that consider the iOS layoutMargins (including safe area insets). Supports two components for easy usage (<ContentInsetView /> and <ContentInsetFlatList />) and a method for querying the margins of the current root view.

Please read the iOS Layout Design Guides for more details on the layout margins.

Based on delightfulstudio/react-native-safe-area-insets.

Installation

yarn add @dioncodes/react-native-layout-margins
cd ios && pod install

Important: If you are updating from version 1.2 or earlier and using the components, you will need to add the LayoutMarginProvider (see Component Usage below).

Manual linking

1. Open your project in XCode
2. Add ./node_modules/@dioncodes/react-native-layout-margins/ios/RNLayoutMargins.xcodeproj to Libraries in your project
3. Select root of your project
4. Switch to General tab
5. Scroll down to Linked Frameworks and Libraries section
6. Click button +
7. Add libRNLayoutMargins.a (if it's not present, build the project and try again)

Component Usage

To use the components you need to wrap your screens into a <LayoutMarginProvider>.

import { LayoutMarginProvider } from '@dioncodes/react-native-layout-margins';
...

const App = () => (
	<LayoutMarginProvider>
		...
	</LayoutMarginProvider>
);

import { ContentInsetView } from '@dioncodes/react-native-layout-margins';
...
<ContentInsetView>
	<Text>I'm aligned according to the iOS layout margins!</Text>
</ContentInsetView>

<ContentInsetView vertical horizontal>
	<Text>I'm aligned according to the iOS layout margins (including safe area), vertically and horizontally.</Text>
</ContentInsetView>

<ContentInsetView vertical>
	<Text>I'm vertically (but not horizontally) aligned according to the iOS layout margins (including safe area).</Text>
</ContentInsetView>

Also supporting a (react-native-gesture-handler) FlatList with content insets:

<ContentInsetFlatList
	data={...}
	renderItem={...}
	keyExtractor={(item) => item.id}
	vertical
	horizontal
/>

Props:

• horizontal (boolean, optional)
• vertical (boolean, optional)
• top (boolean, optional)
• left (boolean, optional)
• right (boolean, optional)
• bottom (boolean, optional)
• style (optional ViewStyle prop that is passed to the View container)

ContentInsetFlatList also accepts all FlatList props.

If no property is set, only the horizontal padding is active.

Manual Usage With provider

import React from 'react';
import { View } from 'react-native';

import { useGetLayoutMarginProvider } from '@dioncodes/react-native-layout-margins';

export default function ExampleScreen() {
	const layoutMarginContext = useGetLayoutMarginProvider();
	const insets = layoutMarginContext.currentInsets;

	const insetStyle = {
		paddingLeft: insets.left,
		paddingRight: insets.right,
	};

	return (
		<View style={insetStyle}>
			<Text>I'm aligned according to the iOS layout margins!</Text>
		</View>
	);
}

Manual Usage Without Provider

import React, { useLayoutEffect, useState } from 'react';
import { View, Dimensions } from 'react-native';

import { currentInsets } from '@dioncodes/react-native-layout-margins';

export default function ExampleScreen() {
	const [insetStyle, setInsetStyle] = useState({ paddingLeft: 0, paddingRight: 0 });

	useLayoutEffect(() => {
		const setInsets = () => {
			currentInsets().then((insets) => {
				setInsetStyle({
					paddingLeft: insets.left,
					paddingRight: insets.right,
				});
			});
		};

		setInsets();
		Dimensions.addEventListener('change', setInsets);

		return function cleanup() {
			Dimensions.removeEventListener('change', setInsets);
		};
	}, []);


	return (
		<View style={insetStyle}>
			<Text>I'm aligned according to the iOS layout margins!</Text>
		</View>
	);
}
