How can I use the contacts_services
plugin or existing code to open the system’s default Add Contact page?
void openAddContacts() async{
if (Platform.isAndroid) {
final AndroidIntent intent = AndroidIntent(
action: 'ContactsContract.Intents.Insert.ACTION',
category: 'ContactsContract.RawContacts.CONTENT_TYPE',
);
await intent.launch();
}
}
