React Native Confirm

Features

• implement ReactDom.Portal in React Native.
• multiple portalhost support.
• programmatically create components and support refresh.
• position configurable for dynamic components, e.g. center,bottom,top,auto.
• support for Confirm Dialog out of box.

Installation And Usage

• install package

• Add the PortalProvider in the Entry Component, e.g App.

// assume we are in render function of App, Wrapper children under PortalProvider
<PortalProvider>
xxx
</PortalProvider>

• Add any PortalHost if needed, elements will be ported under this host. By default, we will create a root Portalhost in the PortalProvider. so you can skip this step, if single portalHost can match your requirement.

<PortalHost name='xxxuniquename'></PortalHost>
