dart JSON String convert to List String

Question

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 1090.95         


        

Answer 1

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

You can cast such a list to a List as

List stringList = (jsonDecode(input) as List).cast();

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

List 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.
