flutter_currency_picker's Issues

Not able to change the color of search icon in the popup

Add Rwandan franc - RWF

Please add support for the Rwanda Franc. I have users in this country.

Many thanks.

Add XAF currency

XAF is a currency shared by a couple of countries in central Africa (just like EUR is shared by countries in Europe).
My app targets users in those regions.

Could you add support for this currency?

Thanks

Use emoji flags directly instead of computing them

I'm experiencing a noticable delay when opening the currency picker widget. I guess because it has to compute more than 200 flags when generating the listview.
Can we just add the emoji data directly to the list?
I think that will boost the performance of the package.
What do you think?

Add Guatemalan QUETZAL currency

More info: wikipedia

please add currency for cubs , angola , snegal , sudan .

Incorrect currency symbols

I went over all the currency symbols after I noticed one of them (KZT) didn't seem right, and found that some may be incorrect. As far as I can tell by looking at a number of websites**, these seem to be the right symbols for the following currencies:

AMD ֏
BYN Br
GHS ₵
KZT 〒
MDL L
PYG ₲
RON L

** these 2 seem to be the most complete references I found. I tried to go with the most agreed upon symbols. The second link says those are the ISO codes, but iso.org charges $41 for the PDF with the codes, so I couldn't double check it... it's hard to find consistent answers on the internet.

https://www.foreignexchangelive.com/currency-codes-symbols/
https://github.com/smirzaei/currency-formatter/blob/master/currencies.json

Kazakhstan decimal seperator

Is there a reason why the decimal seperator for KZT is set to "-"?

Wikipedia says its a comma.
https://www.wikiwand.com/en/Decimal_mark

Null Safety

When are you planning to move it to null safe ?

Offer a way to mark a currency as the selected one

As the user is able to select a currency and then open the picker again, the picker should be smart enough to mark the selected currency in some way. Maybe a tick ✔️? And maybe the list should be scrolled to show that value when showing the picker.

Add cryptocurrencies

It would be great if you could add some cryptocurrencies to the list. Here I have the first 19.

I think the flag stuff should be modified to hold images also instead of the current String? variable type. Also, the icons should be retrieved from assets I think.

Thank you for your nice work.

Currency symbol on Android showing incorrectly

Hey, no idea what I'm doing wrong here but the picker shows the currency symbols correctly but when I use any of those symbols in a Text(currency.symbol) I get a box with a question mark inside. This happens for several selections but reproducible with the Russia Ruble. Using a Pixel 6 Pro, Android 12. Any suggestions?

Give a way to return the currency related to a locale

As this project has a lot of information about the currencies, it would be great to use it to retrieve the Currency related to a given Locale.

Adjustable height for picker bottom sheet

Hi,

Can you add a property to set the height of bottom sheet or even better to have an adjustable height from few elements until a specific max height (many scrollable elements)

just as for example : https://pub.dev/packages/map_launcher

Currency added in favorite and currencyFilter are showing twice

Currency added in favorite and currencyFilter are showing twice in the popup

sample code to induce error

        showCurrencyPicker(

          currencyFilter: ['eur', 'inr', 'usd'],
          favorite: ['eur', 'inr', 'usd'],
        );

CurrencyListView

Please can you expose CurrencyListView so that it can be used also independent of the BottomSheet

Add the Seychellois rupees

Hello Daniel! I wanted to make a PR to add the Seychellois rupees to the list of currencies but I'm not sure about the number field. And I don't have the flag yet. So I'm opening an issue in case you can add it easily, or as a reminder for me to make the PR :·)

Currency removal

I am using the currency picker not only for picking the currency but also for all the helpful information about the currencies in currencies.dart.

By removing former currencies from currencies.dart, like the croatian kuna, I cant display former usages properly.

Proposal: Mark former currencies as removed and dont show them in the currency picker but leave them in currencies.dart (as long as the currency code isnt needed).

Translated languages names

How can I modify this?

Order list according to most traded statistics

Would be nice to sort the list by usage, not by ABC

https://en.wikipedia.org/wiki/Template:Most_traded_currencies

More options: preselect a currency , and multiselect several currencies

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.

More currency-related info will be appreciated

Letting the user select the currency has some impacts not only on the currency name/symbol to show.

There are some currencies that show the symbol before the amount while others after. There're also some currencies that are a space between the symbol and the amount, and not all currencies show the same decimal digits.

I think that gives this information when the user selects a currency will be really helpful.

I've found a JSON file from another library that has this information, so it will not be too hard to add it:

The currencies shouldn't know about the decimal and the thousands separator

Hello!

Playing around with the picker, I've noticed the Currency class has decimalSeparator and thousandsSeparator fields.

I think they shouldn't, because that is related with the device language, not the currency itself.

An example: in Catalan and Spanish, we use the comma as a decimal separator and the dot as a thousand separator for both numbers and currencies. And the opposite: in English, the comma is for the thousands and the dot for the decimals, for both numbers and currencies.

What do you think?

Thanks!

Implement the option to add custom hint for the Search and the option to show/hide the currency name

Please add the possibility to specify a custom hint instead of the default "Search", and add the option to show or not show the subtitles in each element of the list.
Thank you :)

Order the currencies alphabetically

Right now, the currencies are ordered by their usage, according to a comment in currencies.dart.

As the library offers a way to show the favorite currencies in the beginning of the list, don't you think we should show the most used currencies there, like EUR or USD, and then order the rest alphabetically? A user that scrolls the list looking for the ethiopian birr doesn't care about the most traded currencies. I know there's a search text field, but as a user, honestly, you find that search text field when you finished scrolling the list 😅

May we order them alphabetically?

Thanks a lot, by the way!
