CodePudding user response：

You can change list type to var and get rid of first

String data = "example#example";
var list = data.split('#');
print(list);

CodePudding user response：

data.split('#') will provide a list. You can loop though item.

  final data = "example#example";
  final list = data.split('#');
  for (final item in list) { // will print one by one.
    print(item);
  }
  final outPut = list.join(" "); //You can join the list. 
  print(outPut); //example example

If you mean to widget not printing, here's a solution.

const String data = "example#example";
final List<String> list = data.split('#');
return Column(
  children: <Widget>[
    ...list.map((String e) => Text(e)),
  ],
);
