Split & join String in dart

In Dart, you can split a string into a list of substrings using the split() method, and you can join a list of strings into a single string using the join() method.

Example:

void main() {
  List<String> parts = ["Hello", "World!"];

  String str = "Hello, Jeet";

  print(str.split(','));
  print(parts.join(',')); // Output: Hello, World!
}
