 == Why is this an issue?
 
-Nullability of types is an important part of Dart's type system. In order to simplify the work with nullable types in the Dart language there are many null-aware operators (`??`, `??=`, `?.`, `!`, `?..`, `?[]`, `...?`). Using those operators will make your code more clear and concise.
+Nullability of types is an important part of Dart's type system. In order to simplify the work with nullable types in the Dart language there are many null-aware operators (`??`, `??=`, `?.`, `!`, `?..`, `?[]`, ``++...?++``). Using those operators will make your code more clear and concise.
 
 The If-null operator (`??`), will check if the value on the left side is `null`, and, if yes, will return the expression on the right. This is an easy way to set default values instead of dealing with `null`. Thus, this operator doesn't make sense if used with `null` on either sides.
