How to remove all whitespace of a string in Dart?

Question

Using trim() to eliminate white space in Dart and it doesn\'t work. What am I doing wrong or is there an alternative?

       String product = \"COC

In case this is of any help to someone in the future, for convenience you can define an extension method to the String class:

extension StringExtensions on String {
  String removeWhitespace() {
    return this.replaceAll(' ', '');
  }
}

This can be called like product.removeWhiteSpace() I've used it in the past to create a helper method when sorting lists by a string whilst ignoring case and whitespace

extension StringExtensions on String {
  String toSortable() {
    return this.toLowerCase().replaceAll(' ', '');
  }
}
