Getting started

This package assumes that you already have a React Native project or are familiar with React Native. If not, checkout the official documentation for more details about getting started with React Native.

The following is required for the package to work properly.

Step 1. - Install

Install the react-native-calendar-events library with native code.

npm install --save  @fatihergin/[email protected]

Step 2. - Link the library

Since this package contains native code, you will need to include the code as a library. The React Native documentation on "Linking Libraries" also provides some details for this process.

• Automatic linking

react-native link

• Manual linking Sometimes "automatic linking" is not sufficient or is not properly including the library. Fortunately, the React Native docs on "Manual Linking" serves a helpful guide (with pictures) in the process.

Step 3. - OS specific setup

• iOS specific instructions iOS specific requirements, such as mandatory privacy usage descriptions and including the EventKit.framework.

• Android specific instructions Android specific requirements, such as mandatory application permissions.
