How to get data from SQLite Database and add the data to Picker in Xamarin Forms?

I am trying to get the data from my SQLite database to and bind the data to my picker. How can I get multiple data from my SQLite database into my picker? Below is my code I started to query my SQLite database but I don’t know how to get the data I needed and add it to my picker.

> Picker ItemsSource="{Binding Retailer}" ItemDisplayBinding="{Binding RetailerName}"

public string Retailer
{
get { return retailer; }
set
{
retailer = value;
OnPropertyChanged(nameof(Retailer));
}
}

public void SetRetailerPicker()
{
var db = DependencyService.Get<ISQLiteDB>();
var conn = db.GetConnection();

var getRetailer = conn.QueryAsync<ContactsTable>(“SELECT FileAs FROM tblContacts”);
var result = getRetailer.Result;
}
