Error in adding phone number to contacts_service

Question

I am trying to add a contact to the phone from a json data in flutter.

I have used contacts_service package. But I when I am trying to add the phone number to the model,"a String cant be assigned to a iterable error pops".

Could someone show the correct method of using this package and adding a contact.

My code is

onSaved: (val) =>
setState(() => _user.phones = val)),

Answer 1

As mentioned in the docs , phones is an Iterable of Item , not an unique String :

// Phone numbers
Iterable<Item> phones = [];

where Item is a basic key / value object.

You need to format your val this way:

onSaved: (val) =>
    setState((){
        _user.phones = []..add(Item.fromMap({'label': 'work', 'value': val})); // Set the label of your choice
    });
),
