avoiding resorting countries array

[mwk24]

I was just needing 3 countries, and it's much easier to just show them in the order specified in the countries array to the widget.

Thanks!

Maybe let's return Country.fromJson(country) inside the first loop instead of in another loop on 27?

Suggested change

	List filteredList = countries
	.map((countryCode) => jsonList.firstWhere((country) => country[PropertyName] == countryCode,
	orElse: () => null))
	.toList();
	return filteredList.map((country) => Country.fromJson(country)).toList();
	final filteredList = countries.map((countryCode) {
	final _country = jsonList.firstWhere(
	(country) => country[PropertyName] == countryCode,
	orElse: () => null,
	);
	if (_country == null) return null;
	return Country.fromJson(_country);
	}).where((c) => c != null).toList();
