Here is the line of code the causes the error

var currencyData = await http.get(Uri.parse('https://rest.coinapi.io/v1/exchangerate/BTC/USD?apikey=------------------------'));

CodePudding user response：

This is a https protocol issue. Since the url is working fine, is more like that there is a problem with your device. Trying adjust its clock may fix this problem because https needs both, client and sever, to have the same current time. If this problem persists, try to run your code in a different device.
