valid_regexps
Invalid regular expression syntax.
Description
#The analyzer produces this diagnostic when the string passed to the
default constructor of the class RegExp doesn't contain a valid regular
expression.
A regular expression created with invalid syntax will throw a
FormatException at runtime.
Example
#The following code produces this diagnostic because the regular expression isn't valid:
dart
var r = RegExp(r'(');Common fixes
#Fix the regular expression:
dart
var r = RegExp(r'\(');
