var dataURL = "http://api.k780.com?app=finance.rate&scur=CNY&tcur=GBP&appkey=35134&sign=fb020c3129435bb5ff21b7113e9cb1c1&format=json";
print(dataURL);
var response = await http.get(
dataURL);
print(response.statusCode);
print(response.headers);
print(response.body);can't resolve response.body
but when I use UTF8Codec class resolve bodybytes ,it works!
print(Utf8Codec().decode(response.bodyBytes));here is success log:
