How to replace a Single Backslash '\\' in a String with double Backslash '\\' ?
I tried this, but its not working.
main(){
String string = "back\slash back\slash back\slash back\slash";
String replaced = string.replaceAll(RegExp(r'\\'), '\\\\');
print(replaced);
}
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.
