Solution

You can do this:

final lst = [{"ask":"28.47500","bid":"27.47500","name":"USDUAH","time":"1616772920.000"},
{"ask":"3972.06000","bid":"3971.16000","name":"SPX","time":"1617047940.000"},
{"ask":"0.71965","bid":"0.71916","name":"AUDCHF","time":"1617076421.403"}];

final res = lst.where((element) => element['name'] == 'SPX').toList();
