MateusAndrade cc13a7367b Improving Modal `visible` prop check to handle undefined and null (#22072)
Summary:
Changing the the this.props.visible if to be ` if (!!this.props.visible === false)` . So passing undefined, or other values wont set the modal to be visible. Granting that anything that is not true, will set the modal to null on the render.

I make this this PR, because on the company that im working, we used a lot of RN. At the moment, we arent using anything like flow or TS. But to grant that the modals will only show if they are set visible to true i have changed the if made.

_Pull requests that expand test coverage are more likely to get reviewed. Add a test case whenever possible!_

React Native · Circle CI Status Build status npm version PRs Welcome

Learn once, write anywhere: Build mobile apps with React.

See the official React Native website for an introduction to React Native.


Requirements

Supported target operating systems are >= Android 4.1 (API 16) and >= iOS 9.0. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS by default (tools like Expo can be used to get around this).

Building your first React Native app

Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:

How React Native works

React Native lets you build mobile apps using JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.

With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C, Java, Kotlin, or Swift. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.

React Native lets you build your app faster. Instead of recompiling, you can reload your app instantly. With hot reloading, you can even run new code while retaining your application state.

React Native combines smoothly with components written in Objective-C, Java, Kotlin, or Swift. It's simple to drop down to native code if you need to optimize a few aspects of your application. It's also easy to build part of your app in React Native, and part of your app using native code directly - that's how the Facebook app works.

The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.

Full documentation

The full documentation for React Native can be found on our website. The source for the React Native documentation and website is hosted on a separate repo, https://github.com/facebook/react-native-website.

The React Native documentation only discusses the components, APIs, and topics specific to React Native (React on iOS and Android). For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
