![]() ![]() One of the most popular choices is to use D3js. But there are some other options available for React Native apps. When it comes to building interactive applications with React, the most common framework for developing user interfaces is ReactJS. There are also several tutorials and full-fledged courses (both free and paid) to help you learn how to use it. ![]() The React Native community is so strong and there are numerous resources available online in case you get stuck or need help with something. It also allows UI components to behave natively on each platform, making the apps feel like they were built from scratch for it. It has a vast library of components and modules that allow developers to use the same set of tools for cross-platform app development. React Native is an open source framework that helps you build mobile apps using JavaScript and React. const styles = StyleSheet.How to Choose the Best Framework for Your React Native Project? To achieve equal height, set the height of the box to that of the value that we calculated earlier. Setting flexDirection to column means that the children of the container will be laid out vertically (stacked on top of each other), while setting it to row means that the children will be laid out horizontally (side by side). We'll take a look at an example of using flex with siblings later on.įlexDirection allows you to specify the primary axis of the layout. If it's 1, it means that it will consume all the available space, provided that the element has no siblings. ![]() The value is the amount of space it will consume. To use Flexbox, you must use the flex property on the container. Common styles are declared in the box object, and unique background colors are applied to uniquely named objects ( box1, box2, box3): Here's the code to accomplish the layout above: import React from 'react' Ĭonst = Dimensions.get('window') įor the markup, the boxes should be wrapped inside a container. Let's take a look at vertical orientation first: For vertical orientation, it stacks elements on top of each other, while for horizontal orientation, the elements are placed side by side. The first kind of layout that we will implement is the Stack Layout. This means that we can only do layouts using Flexbox and CSS positioning. It's also worth noting that there are no floats or percentage-based units in React Native. (I say "subset" because not all features that are in the Flexbox specification are included.) So if you already know Flexbox, then you can readily apply those skills in React Native. Layouts in React Native use a subset of Flexbox. Import FlexStart from "./layouts/FlexStart" For example, if we have layouts/FlexStart.js, do the following in App.js: import * as React from 'react' Just remember that any component that we save in the layouts directory shouldn't be rendered with anything else. ![]() Later on, you can import the components that we'll be creating and then render them from this file. Open the App.js file and replace the default code with the following: import * as React from 'react' To set up the project for adding layouts, you need to do two things: Later, you can also just export it to a local file using the Download as ZIP button in the top-right corner, and then use it like a local project. To simplify things, we are using Expo Snack, which is like CodePen but for React Native. I'll be assuming that you already know the basics of styling a React Native app and how to use CSS in general, so I won't dwell too much on StyleSheet.create and how to add styling to different elements. This includes the Stack Layout, Grid Layout, and Absolute Layout. In this tutorial, you'll learn how to lay out React Native apps and how to implement layouts commonly used in apps. ![]()
