Split String in flutter

Question

I using split method to split the String.

String date = "2020-10-07";
date.split("-");
print("split " + date[0]);

I expect will get 2020, but why it return 2 ?

Answer 1

The reason you are getting 2 is because it is the first position (0) of the string variable date.

When you split a string, it will return a list/array.

String date = "2020-10-07";
final dateList = date.split("-");
print("split " + dateList[0]);
//expected "split 2020"

Answer 2

It is 2 because there no change has been done to the variable date( the same without the split), but with split you can access the list like this below

String date = "2020-10-07";
var first = date.split("-").first;//returns the first element of the list
print("split " + first);
