How to replace Backslash '\' with double Backslash in Dart?
5,535
The problem is that the string string
does not contain any \
It would either need to be
String string = r"back\slash back\slash back\slash back\slash";
or
String string = "back\\slash back\\slash back\\slash back\\slash";
In your example there also is no need for RegExp. Just
String replaced = string.replaceAll(r'\', r'\\');
would do as well.
