Getting Started #

Installation #

Add countrify to your pubspec.yaml:

dependencies:
  countrify: ^1.0.2

Then run:

flutter pub get

Import #

import 'package:countrify/countrify.dart';

Quick Start #

The simplest way to show a country picker:

final country = await ModalComprehensivePicker.showBottomSheet(
  context: context,
);

if (country != null) {
  print('Selected: ${country.name}');
  print('Code: ${country.alpha2Code}');
  print('Phone: +${country.callingCodes.first}');
}

Display Modes #

Countrify supports five display modes out of the box. Each mode is suited for different UI scenarios.

1. Bottom Sheet #

A modal bottom sheet that slides up from the bottom of the screen. Best for mobile-first UIs.

final country = await ModalComprehensivePicker.showBottomSheet(
  context: context,
  showPhoneCode: true,
  searchEnabled: true,
);

2. Dialog #

A centered dialog popup. Best for tablet and desktop layouts.

final country = await ModalComprehensivePicker.showDialog(
  context: context,
  showPhoneCode: true,
  searchEnabled: true,
);

3. Full Screen #

A full-screen page with an AppBar. Best for complex selection flows.

final country = await ModalComprehensivePicker.showFullScreen(
  context: context,
  showPhoneCode: true,
  searchEnabled: true,
);

4. Dropdown #

An embeddable dropdown widget that shows the selected country and opens a popup menu when tapped. Best for forms.

ModalComprehensivePicker.dropdown(
  initialCountry: selectedCountry,
  onCountrySelected: (country) {
    setState(() => selectedCountry = country);
  },
  showPhoneCode: true,
  showFlag: true,
  showCountryName: true,
)

5. Inline #

An inline picker that renders directly within your layout. Best for dashboard or settings pages.

ModalComprehensivePicker.showInline(
  initialCountry: selectedCountry,
  onCountrySelected: (country) {
    setState(() => selectedCountry = country);
  },
  showPhoneCode: true,
  searchEnabled: true,
)

Widgets #

ModalComprehensivePicker #

The primary API for showing country pickers. Provides static methods for all display modes.

// All modal methods share these common parameters:
final country = await ModalComprehensivePicker.showBottomSheet(
  context: context,
  initialCountry: preselectedCountry,     // Pre-select a country
  onCountrySelected: (country) { },       // Callback on selection
  onCountryChanged: (country) { },        // Callback on change
  onSearchChanged: (query) { },           // Callback on search input
  onFilterChanged: (filter) { },          // Callback on filter change
  theme: CountryPickerTheme.darkTheme(),  // Apply a theme
  config: const CountryPickerConfig(),    // Configuration options
  showPhoneCode: true,                    // Show calling codes
  showFlag: true,                         // Show flag images
  showCountryName: true,                  // Show country names
  showCapital: false,                     // Show capital cities
  showRegion: false,                      // Show geographic regions
  showPopulation: false,                  // Show population
  searchEnabled: true,                    // Enable search bar
  filterEnabled: false,                   // Enable filter chips
  hapticFeedback: true,                   // Enable haptic feedback
);

  context: context,
  initialCountry: selectedCountry,
);

// Full screen
final country = await ModalCountryPicker.showFullScreen(
  context: context,
  initialCountry: selectedCountry,
);

Theming #

Countrify ships with 4 theme presets and supports fully custom themes. Every visual aspect of the picker is themeable.

Built-in Themes #

// Default light theme
CountryPickerTheme.defaultTheme()

// Dark theme
CountryPickerTheme.darkTheme()

// Material Design 3 theme
CountryPickerTheme.material3Theme()

// Custom theme from a primary color
CountryPickerTheme.custom(
  primaryColor: Colors.teal,

  isDark: false,
)

Applying a Theme #

final country = await ModalComprehensivePicker.showBottomSheet(
  context: context,
  theme: CountryPickerTheme.darkTheme(),
);

Custom Themes #

Use CountryPickerTheme.custom() for quick theming, or copyWith() for fine-grained control:

final customTheme = CountryPickerTheme.custom(
  primaryColor: Colors.deepPurple,
  backgroundColor: Colors.white,
  isDark: false,
).copyWith(
  countryItemBorderRadius: BorderRadius.circular(16),
  searchBarBorderRadius: BorderRadius.circular(24),

Configuration #

Use CountryPickerConfig to control picker behavior, data display, flag styling, filtering, sorting, and custom builders.

Display Options #

const config = CountryPickerConfig(
  showDialCode: true,         // Show phone/dial codes
  showCapital: false,         // Show capital cities
  showRegion: false,          // Show geographic regions

);

Flag Customization #

Countrify supports three flag shapes with full border and shadow control.

// Circular flags
const config = CountryPickerConfig(
  flagShape: FlagShape.circular,
  flagSize: Size(40, 40),
);

// Rounded flags
const config = CountryPickerConfig(
  flagShape: FlagShape.rounded,
  flagSize: Size(40, 28),
);

// Flags with shadows
const config = CountryPickerConfig(
  flagShape: FlagShape.rectangular,
  flagSize: Size(42, 30),
  flagBorderRadius: BorderRadius.all(Radius.circular(6)),
  flagShadowColor: Colors.black26,
  flagShadowBlur: 6,
  flagShadowOffset: Offset(0, 3),
);

// Flags with border
const config = CountryPickerConfig(
  flagBorderColor: Colors.grey,
  flagBorderWidth: 2.0,
);

Filtering Countries #

const config = CountryPickerConfig(
  // Include only specific regions
  includeRegions: ['Europe', 'Asia'],

  // Exclude specific regions
  excludeRegions: ['Antarctica'],

  // Include only specific countries (by alpha-2 code)
  includeCountries: ['US', 'CA', 'GB', 'DE', 'FR'],

  // Exclude specific countries (by alpha-2 code)
  excludeCountries: ['XX'],

  // Filter by status
  includeIndependent: true,
  includeUnMembers: true,
);

Sorting #

const config = CountryPickerConfig(
  sortBy: CountrySortBy.name,        // Alphabetical (default)
  // sortBy: CountrySortBy.population, // Most populous first
  // sortBy: CountrySortBy.area,       // Largest area first
  // sortBy: CountrySortBy.region,     // Grouped by region
  // sortBy: CountrySortBy.capital,    // Alphabetical by capital
);

Sizing #

const config = CountryPickerConfig(
  itemHeight: 60.0,           // Height of each country item
  maxHeight: 600.0,           // Maximum picker height
  minHeight: 200.0,           // Minimum picker height
  dropdownMaxHeight: 400.0,   // Maximum dropdown menu height
);

Custom Builders #

Override the default UI with your own widgets:

CountryPickerConfig(
  // Custom country item
  customCountryBuilder: (context, country, isSelected) {
    return ListTile(
      leading: Image.asset(
        country.flagImagePath,
        package: 'countrify',
        width: 32,
        height: 24,
      ),
      title: Text(country.name),
      subtitle: Text('+${country.callingCodes.first}'),
      trailing: isSelected
          ? const Icon(Icons.check_circle, color: Colors.blue)
          : null,
    );
  },

  // Custom header
  customHeaderBuilder: (context) {
    return const Padding(
      padding: EdgeInsets.all(16),
      child: Text('Pick Your Country',
          style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold)),
    );
  },

  // Custom search bar
  customSearchBuilder: (context, controller, onChanged) {
    return Padding(
      padding: const EdgeInsets.all(16),
      child: TextField(
        controller: controller,
        onChanged: onChanged,
        decoration: const InputDecoration(
          hintText: 'Type to search...',
          prefixIcon: Icon(Icons.search),
        ),
      ),
    );
  },

  // Custom filter bar
  customFilterBuilder: (context, filter, onChanged) {
    return Wrap(
      children: ['Europe', 'Asia', 'Africa'].map((region) {
        return FilterChip(
          label: Text(region),
          selected: filter.regions.contains(region),
          onSelected: (selected) {
            final regions = selected
                ? [...filter.regions, region]
                : filter.regions.where((r) => r != region).toList();
            onChanged(filter.copyWith(regions: regions));
          },
        );
      }).toList(),
    );
  },
)

Country Data & Utilities #

Use CountryUtils to access country data programmatically without showing any picker UI.

Fetching Countries #

// Get all 245+ countries
final countries = CountryUtils.getAllCountries();

// Get by ISO code
final usa = CountryUtils.getCountryByAlpha2Code('US');
final canada = CountryUtils.getCountryByAlpha3Code('CAN');
final germany = CountryUtils.getCountryByNumericCode('276');

// Search by name (case-insensitive)
final results = CountryUtils.searchCountries('united');

// Get by region or subregion
final european = CountryUtils.getCountriesByRegion('Europe');
final southAmerican = CountryUtils.getCountriesBySubregion('South America');

// Get by calling code
final countriesWith1 = CountryUtils.getCountriesByCallingCode('+1');

// Get by currency
final euroCountries = CountryUtils.getCountriesByCurrencyCode('EUR');

// Get by language
final englishSpeaking = CountryUtils.getCountriesByLanguageCode('en');

// Get bordering countries
final neighbors = CountryUtils.getBorderCountries('USA');

Sorting #

final byPopulation = CountryUtils.getCountriesSortedByPopulation();
final byArea = CountryUtils.getCountriesSortedByArea();
final alphabetical = CountryUtils.getCountriesSortedByName();

Filtered Collections #

final independent = CountryUtils.getIndependentCountries();
final unMembers = CountryUtils.getUnMemberCountries();

Statistics #

final totalPopulation = CountryUtils.getTotalWorldPopulation();
final totalArea = CountryUtils.getTotalWorldArea();

final mostPopulous = CountryUtils.getMostPopulousCountry();
final largest = CountryUtils.getLargestCountry();
final smallest = CountryUtils.getSmallestCountry();

// Formatted output
print(CountryUtils.formatPopulation(totalPopulation)); // "7,794,798,739"
print(CountryUtils.formatArea(totalArea));              // "148,940,000.00"

Metadata Lookups #

final regions = CountryUtils.getAllRegions();         // ["Africa", "Americas", ...]
final subregions = CountryUtils.getAllSubregions();   // ["Caribbean", "Central Asia", ...]
final currencies = CountryUtils.getAllCurrencies();
final languages = CountryUtils.getAllLanguages();
final timezones = CountryUtils.getAllTimezones();

Validation #

CountryUtils.isValidAlpha2Code('US');   // true
CountryUtils.isValidAlpha3Code('USA');  // true
CountryUtils.isValidNumericCode('840'); // true
CountryUtils.isValidAlpha2Code('XX');   // false

Country Model #

Each Country object contains comprehensive data:

Using Flag Images Directly #

When displaying a country's flag outside of the picker widgets, always include the package parameter:

Image.asset(
  country.flagImagePath,
  package: 'countrify',  // Required when using outside the package
  width: 32,
  height: 24,
)

Troubleshooting #

Flag images not loading

When using flag images outside of the built-in picker widgets, always include the package parameter:

Image.asset(
  country.flagImagePath,
  package: 'countrify',  // Don't forget this!
  width: 32,
  height: 24,
)
Picker not appearing

Ensure the BuildContext is valid and the widget is still mounted:

if (mounted) {
  final country = await ModalComprehensivePicker.showBottomSheet(
    context: context,
  );
}
Country not found by code

Country codes must be uppercase:

final country = CountryUtils.getCountryByAlpha2Code('US'); // Correct
// Not: CountryUtils.getCountryByAlpha2Code('us');          // Wrong
Selected country not appearing at top of list

Pass the initialCountry parameter so the picker places it at the top:

final country = await ModalComprehensivePicker.showBottomSheet(
  context: context,
  initialCountry: _selectedCountry,
);
PhoneNumberField dropdown not dismissing

The dropdown overlay dismisses when tapping outside it. If you're embedding PhoneNumberField in a scrollable view, ensure the overlay has space to render below the field. You can adjust dropdownMaxHeight to control its size.

What's the difference between ModalComprehensivePicker and ModalCountryPicker?

ModalComprehensivePicker uses the advanced ComprehensiveCountryPicker widget with rich theming, filtering, and all 5 display modes. ModalCountryPicker is a simpler API using the basic CountryPicker widget with fewer customization options. For new projects, prefer ModalComprehensivePicker.

CountryDropdownField is a form field for selecting a country (displays country name/flag). PhoneNumberField is a complete phone input widget that combines a country code picker prefix with a text input for the phone number.
