  //
  // The analyzer produces this diagnostic when a function type associated with
  // a parameter includes optional parameters that have a default value. This
  // isn't allowed because the default values of parameters aren't part of the
  // function's type, and therefore including them doesn't provide any value.
  //
  // #### Example
  //
  // The following code produces this diagnostic because the parameter `p` has a
  // default value even though it's part of the type of the parameter `g`:
  //
  // ```dart
  // void f(void Function([int p [!=!] 0]) g) {
  // }
  // ```
  //
  // #### Common fixes
  //
  // Remove the default value from the function-type's parameter:
  //
  // ```dart
  // void f(void Function([int p]) g) {
  // }
  // ```

  //
  // ```dart

  // extension E on String {
  //   String [!s!];
