This looks like a simple question, but I couldn't find any result after google.
I have string tel：090-1234-9876 03-9876-4321 +81-90-1987-3254, I want to split it to tel：, 090-1234-9876, 03-9876-4321 and +81-90-1987-3254, what can I do?

use `[]` for regex as `or` and put any sign you want to split : `str.split(RegExp(r'[ ：]'));` – yellowgray Jan 03 '21 at 13:34

Simply you can use the split() method of the Dart as follows.
final str = "tel：090-1234-9876 03-9876-4321 +81-90-1987-3254";
print(str.split(" "));
If you want to use any other pattern, try splitting using regex.
final str = "tel: 090-1234-9876 03-9876-4321 +81-90-1987-3254";
print(str.split(RegExp(r'\s')));
// outputs: [tel:, 090-1234-9876, 03-9876-4321, +81-90-1987-3254]
Additionally, if you want to split by multiple delimiters e.g by +, -, and \s then
final str = "tel: 090-1234-9876 03-9876-4321 +81-90-1987-3254";
print(str.split(RegExp(r'[+-\s]')));
// outputs: [tel:, 090, 1234, 9876, 03, 9876, 4321, , 81, 90, 1987, 3254]

Use dart's String.split(Pattern) method!!
String telnums = 'tel：090-1234-9876 03-9876-4321 +81-90-1987-3254';
List<String> splitValues = telnums.split(" ");
In fact, you can use any regex (Regex), String or pattern (Pattern)

what can I split `：`, ` ` and ` `? you only split one of them what I knew... – mikezang Jan 03 '21 at 12:48

@mikezang, you could use regex to do that and could you please explain what do you mean by 'only split one of them'? – sidrao2006 Jan 03 '21 at 13:28

Your example didn't split on colon. Colon is still part of the first element returned. – Randal Schwartz Jan 03 '21 at 18:06
