More options: preselect a currency , and multiselect several currencies

[giorgio79]

Would be nice to have a preselect array option, so one or more currencies can be preselected.
I am working on an app that has a currency selector and do some geolocation magic, and preselect the currency based on user geolocationn https://play.google.com/store/apps/details?id=com.cashtic

Also, the capability to multiselect would be great too.

If anyone needs this functionality here is the code for getting user currency by location. It needs the geolocator and Google Maps api for reverse geocoding

//https://pub.dev/documentation/geocoding/latest/geocoding/placemarkFromCoordinates.html
      userGeolocatorPlacemark = await placemarkFromCoordinates(
          globals.geolocatorPosition.latitude,
          globals.geolocatorPosition.longitude);

      //get currency code for country
      //https://stackoverflow.com/questions/58766133/how-to-get-currency-and-currency-symbol-in-flutter-by-country-code
      userCurrencyByLocationCountry = CurrencyPickerUtils.getCountryByIsoCode(
              userGeolocatorPlacemark[0].isoCountryCode)
          .currencyCode;

@giorgio79 I'm not sure what you mean preselected currencies, package dose not keep the selected currency, it only return the selected currency through onSelect callback.

If you want to show one or more currencies at the top of the list you can use favorite parameter:

   showCurrencyPicker(
     context: context,
     onSelect: (Currency currency) {
       print('Select currency: ${currency.name}');
     },
     favorite: <String> ['EUR', 'GBP', 'USD'],
   );

Yeah, so if someone selects values and then the app saves it to Firebase or some storage, the next time the user edits the selected currencies, the saved values could be preloaded...

@giorgio79 the way I handled this on my app was to put the previously selected currency as a favorite, so it shows at the top of the list in a separate box right under the search box. The user can just tap it again right away.

A preselected currency is possible right now but i have to use an ugly workaround. It would be nice if you could make currencies.dart available through a getter so we could set a new/initial Currency easily.

To make clear what preselected means: I have a button that shows a currency, the user can click it and change it to a different currency if he wants to. This button uses the currency_picker Currency class for getting the symbol and to draw the flag.
