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.

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) { ... }
