Android Integration

The following will need to be added to the manifest file for your application to indicate permissions to modify calendars a needed

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

If you have Proguard enabled, you may need to add the following to your configuration (thanks to Britannio Jarrett who posted about it here)

-keep class com.builttoroam.devicecalendar.** { *; }

If you want to enable Proguard, please refer to the guide at Android Developer page

If you consider to publish the app and build a release version you have to enable Proguard. Follow these steps: here.

IMPORTANT: Since version 0.1.0, this version has migrated to use AndroidX instead of the deprecated Android support libraries. When using version 0.10.0 and onwards for this plugin, please ensure your application has been migrated following the guide here

iOS Integration

For iOS 10 support, you'll need to modify the Info.plist to add the following key/value pair

<key>NSCalendarsUsageDescription</key>
<string>INSERT_REASON_HERE</string>

Note that on iOS, this is a Swift plugin. There is a known issue being tracked here by the Flutter team, where adding a plugin developed in Swift to an Objective-C project causes problems. If you run into such issues, please look at the suggested workarounds there.
