country_io 1.0.0

countryIO #

A simple data parser, written with ❤️ using Dart :)

Show some ❤️ by putting ⭐ :)

what does it do ? #

This Dart package can be used to fetch country data from, which includes country iso2 code, country name, capital name, continent code, currency code & phone code, which will be eventually stored in a json encoded file, whose path needs to be provided to Generator class constructor.

how to use ? #

Well using this package for generating json encoded file, holding country data, is pretty much easy.

Simply invoke Generator constructor with a valid path to target data.json file. Calling Generator( ... ).generate(), will start fetching data from, then parsing data and json encoding data for storing in target file.

This function will return a Future<Map<String, Map<String, String>>>, an empty Map denotes failure, otherwise full parsed data set will be returned in form of Map.

Every key of this map will be an iso2 country code, helping to identify a certain country uniquely.

        'continent': continent ?? '',
        'name': name ?? '',
        'iso3': iso3 ?? '',
        'capital': capital ?? '',
        'phone': phone ?? '',
        'currency': currency ?? '',

And value for a certain iso2 country code will be another Map<String, String>, holding detailed country info.

    .then((result) => print(result.isNotEmpty ? 'Success' : 'Failed !!!'));

Yes, it's that simple 😉

Hoping, it helped you a bit (o_o)

v1.0.0 #

what's working ? #

  • Can fetch country data from remote API
  • Can store in local file, if proper file path is provided
  • Generally will return fetched data in form of Map<String, Map<String, String>>, holding detailed data for all countries
  • Feel free to process received data more 😉


import 'package:country_io/country_io.dart';

main() => Generator(
            '../data/data.json') // make sure this path exists i.e. file may not exists, which can be created but you need to have directory already existing, otherwise operation will fail, by returning false
    // if you're not interested in storing it in any file, simply don't pass any argument for targetPath parameter
    .then((result) => print(result.isNotEmpty ? 'Success' : 'Failed !!!'));
