Answer 1

From the examples at this link
List cities = await api.getCities(
countryCode: 'id', region: 'Jawa Timur', keyword: 'mal');
Since you already know which country you want to get the cities from, just assign that country's code to countryCode,
For example, if you want cities of United States with keyword ar,
List<City> cities = await api.getCities(
countryCode: 'us', keyword: 'ar');

Answer 2

I have to agree with the above answer. Given a County you could make a series of calls to get the data set you want.
countries = await api.getCountries(); -- Will return the countries the service has, then search through the list to find the one you want.
regions = await api.getRegions(countryCode: 'id'); -- Will then get you the regions for the country, I'm assuming you'll get the code from the first call, otherwise a good place to start with the code would be to use the the IEEE country codes.

Finally use the regions you got to get the cities;
await api.getCities(countryCode: 'id', region: 'Jawa Timur');
Bringing it all together you'd have something like this... (I have not looked at the API specification so the guess at a memeber in that loop "region.name" is likely incorrect)
import 'package:restcountries/restcountries.dart';
void main() async {
var api = RestCountries.setup(Platform.environment['API_KEY']);
List<Country> countries;
List<Region> regions;
List<City> cities;
countries = await api.getCountries();
// Search here for your country
regions = await api.getRegions(countryCode: '*YOUR COUNTRY CODE HERE*');
// Now we loop to get cities in every region.
regions.forEach((region){
cities += await api.getCities(countryCode: '*YOUR COUNTRY CODE HERE*', region: region.name);
});
print(regions);
print(cities);
}
