How to Use Localization Api to get currency and show them in dropdown

here is how i am getting list of currency but not able to show them inside dropdown Future getCurrency()async{ final res = await locale.listCurrencies(); print(res.currencies); return res.currencies; }

You're not getting a list?

getting list like [instance of Currency, instance of Currency] but not able to show them in droupdown

Then you need to create a dropdown then iterate over the items, like so

https://api.flutter.dev/flutter/material/DropdownButton-class.html

yes i am using map to get all element Future getCurrency()async{ final res = await locale.listCurrencies(); print(res.currencies.map((e) => e.symbol)); return res.currencies.map((e) => e); }

You'll need to use your widget state to add it to drop-down

now, its working, but why some Currency symbols are not correct.

here is the list of all currencies,[$, €, £, $, د.إ.‏, ؋, Lek, դր., $, $, ман., KM, ৳, лв., د.ب.‏, FBu, $, Bs, R$, P, BYR, $, FrCD, CHF, $, CN¥, $, ₡, CV$, Kč, Fdj, kr, RD$, د.ج.‏, kr, ج.م.‏, Nfk, Br, GEL, GH₵, FG, Q, $, L, kn, Ft, Rp, ₪, ₹, د.ع.‏, ﷼, kr, $, د.أ.‏, ￥, Ksh, ៛, FC, ₩, د.ك.‏, тңг., SL Re, Lt, Ls, د.ل.‏, د.م.‏, MDL, MGA, MKD, K, MOP$, MURs, $, RM, MTn, N$, ₦, C$, kr, नेरू, $, ر.ع.‏, B/., S/., ₱, ₨, zł, ₲, ر.ق.‏, RON, дин., руб., FR, ر.س.‏, SDG, kr, $, Ssh, ل.س.‏, ฿, د.ت.‏, T$, TL, $, NT$, TSh, ₴, USh, $, UZS, Bs.F., ₫, FCFA, CFA, ر.ي.‏, R, ZK]
