I have an API that calls the json String array as follows:



[
"006.01.01",
"006.01.01 1090",
"006.01.01 1090 1090.950",
"006.01.01 1090 1090.950 052",
"006.01.01 1090 1090.950 052 A",
"006.01.01 1090 1090.950 052 A 521219",
"006.01.01 1090 1090.950 052 A 521219",
"006.01.01 1090 1090.950 052 A 521219",
"006.01.01 1090 1090.950 052 A 521219",
"006.01.01 1090 1090.950 052 A 521219",
"006.01.01 1090 1090.950 052 B",
"006.01.01 1090 1090.950 052 B 521211",
"006.01.01 1090 1090.950 052 B 521211",
"006.01.01 1090 1090.994",
"006.01.01 1090 1090.994 001",
"006.01.01 1090 1090.994 001 A",
"006.01.01 1090 1090.994 001 A 511111",
"006.01.01 1090 1090.994 001 A 511111",
"006.01.01 1090 1090.994 001 A 511111",
"006.01.01 1090 1090.994 001 A 511111"
]


I intend to convert the json to the List in the dart. I tried the script below :



json.decode(response.body).cast<List<String>();


but it didn't work, how should the script be correct?

          The result of parsing a JSON list is a List<dynamic>. The return type of jsonDecode is just dynamic.



          You can cast such a list to a `List as



          List<String> stringList = (jsonDecode(input) as List<dynamic>).cast<String>();


          You can also just use it as a List<dynamic> and then assign each value to String:



          List<dynamic> rellyAStringList = jsonDecode(input);
          for (String string in reallyAStringList) { ... }


          The effect is approximately the same - each element is checked for being a string when it is taken out of the list.

            The result of parsing a JSON list is a List<dynamic>. The return type of jsonDecode is just dynamic.



            You can cast such a list to a `List as



            List<String> stringList = (jsonDecode(input) as List<dynamic>).cast<String>();


            You can also just use it as a List<dynamic> and then assign each value to String:



            List<dynamic> rellyAStringList = jsonDecode(input);
            for (String string in reallyAStringList) { ... }


            The effect is approximately the same - each element is checked for being a string when it is taken out of the list.
