Though it isn't an issue with this repo, but still it's good you asked.
For what you are stating above you can use contact_services plugin, to fetch contacts list. check this Just wrap Iterable contacts = await ContactsService.getContacts(); in async method and call from initState(). In the tutorial Ronak shown how he managed to get list of Accounts to use in search query, there you just need to fetch only those contacts with same contact no. (Considering you have used Phone Authentication) and you are done.
Your search will only show you those contacts which are registered on your phone.

If still you find any problem, kindly ask and consider closing this issue.
