+  // #### Description
+  //
+  // The analyzer produces this diagnostic when a factory constructor that
+  // redirects to another constructor specifies a default value for an optional
+  // parameter.
+  //
+  // #### Example
+  //
+  // The following code produces this diagnostic because the factory constructor
+  // in `A` has a default value for the optional parameter `x`:
+  //
+  // ```dart
+  // class A {
+  //   factory A([int [!x!] = 0]) = B;
+  // }
+  //
+  // class B implements A {
+  //   B([int x = 1]) {}
+  // }
+  // ```
+  //
+  // #### Common fixes
+  //
+  // Remove the default value from the factory constructor:
+  //
+  // ```dart
+  // class A {
+  //   factory A([int x]) = B;
+  // }
+  //
+  // class B implements A {
+  //   B([int x = 1]) {}
+  // }
+  // ```
+  //
+  // Note that this fix might change the value used when the optional parameter
+  // is omitted. If that happens, and if that change is a problem, then consider
+  // making the optional parameter a required parameter in the factory method:
+  //
+  // ```dart

+  // #### Description
+  //
+  // The analyzer produces this diagnostic when the type of object produced by a
+  // `yield` expression doesn't match the type of objects that are to be
+  // returned from the `Iterable` or `Stream` types that are returned from a
+  // generator (a function or method marked with either `sync*` or `async*`).
+  //
+  // #### Example
+  //
+  // The following code produces this diagnostic because the getter `zero` is
+  // declared to return an `Iterable` that returns integers, but the `yield` is
+  // returning a string from the iterable:
+  //
+  // ```dart
+  // Iterable<int> get zero sync* {
+  //   yield [!'0'!];
+  // }
+  // ```
+  //
+  // #### Common fixes
+  //
+  // If the return type of the function is correct, then fix the expression
+  // following the keyword `yield` to return the correct type:
+  //
+  // ```dart
+  // Iterable<int> get zero sync* {
+  //   yield 0;
+  // }
+  // ```
+  //
+  // If the expression following the `yield` is correct, then change the return
+  // type of the function to allow it:
+  //
+  // ```dart
+  // Iterable<String> get zero sync* {
+  //   yield '0';
+  // }
+  // ```

+{% prettify dart tag=pre+code %}

+
+void g() {

+
+#### Example
+

+
+#### Description
+
+The analyzer produces this diagnostic when a factory constructor that
+redirects to another constructor specifies a default value for an optional
+parameter.
+
+#### Example
+
+The following code produces this diagnostic because the factory constructor
+in `A` has a default value for the optional parameter `x`:
+
+{% prettify dart tag=pre+code %}
+class A {
+  factory A([int [!x!] = 0]) = B;
+}

+If the type of the field is incorrect, then change the type of the field to
+match the type of the parameter, and consider removing the type from the
+parameter:

+### final_initialized_in_declaration_and_constructor
+
+_'{0}' is final and was given a value when it was declared, so it can't be set
+to a new value._
+
+#### Description
+
+The analyzer produces this diagnostic when a final field is initialized
+twice: once where it's declared and once by a constructor's parameter.
+
+#### Example
+
+The following code produces this diagnostic because the field `f` is
+initialized twice:
+
+{% prettify dart tag=pre+code %}
+class C {
+  final int f = 0;
+
+  C(this.[!f!]);
+}
+{% endprettify %}
+
+#### Common fixes
+
+If the field should have the same value for all instances, then remove the
+initialization in the parameter list:
+
+{% prettify dart tag=pre+code %}
+class C {
+  final int f = 0;
+
+  C();
+}
+{% endprettify %}
+
+If the field can have different values in different instances, then remove

+#### Description
+
+The analyzer produces this diagnostic when code in one class references a
+static member in a superclass without prefixing the member's name with the
+name of the superclass. Static members can only be referenced without a
+prefix in the class in which they're declared.
+
+#### Example
+
+The following code produces this diagnostic because the static field `x` is
+referenced in the getter `g` without prefixing it with the name of the
+defining class:
+
+{% prettify dart tag=pre+code %}
+class A {
+  static int x = 3;
+}
+
+class B extends A {
+  int get g => [!x!];
+}
+{% endprettify %}
+
+#### Common fixes
+
+Prefix the name of the static member with the name of the declaring class:
+
+{% prettify dart tag=pre+code %}
+class A {
+  static int x = 3;
+}
+
+class B extends A {
+  int get g => A.x;
+}
+{% endprettify %}

+_URIs can't use string interpolation._
+
+#### Description
+
+The analyzer produces this diagnostic when the string literal in an
+`import`, `export`, or `part` directive contains an interpolation. The
+resolution of the URIs in directives must happen before the declarations
+are compiled, so expressions can’t be  evaluated  while determining the
+values of the URIs.
+
+#### Example
+
+The following code produces this diagnostic because the string in the
+`import` directive contains an interpolation:
+
+{% prettify dart tag=pre+code %}
+import [!'dart:$m'!];
+
+const m = 'math';
+{% endprettify %}
+
+#### Common fixes
+
+Remove the interpolation from the URI:
+
+{% prettify dart tag=pre+code %}
+import 'dart:math';
+
+var zero = min(0, 0);
+{% endprettify %}

+### yield_of_invalid_type
+
+_The type '{0}' implied by the 'yield' expression must be assignable to '{1}'._
+
+#### Description
+
+The analyzer produces this diagnostic when the type of object produced by a
+`yield` expression doesn't match the type of objects that are to be
+returned from the `Iterable` or `Stream` types that are returned from a
+generator (a function or method marked with either `sync*` or `async*`).
+
+#### Example
+
+The following code produces this diagnostic because the getter `zero` is
+declared to return an `Iterable` that returns integers, but the `yield` is
+returning a string from the iterable:
+
+{% prettify dart tag=pre+code %}
+Iterable<int> get zero sync* {
+  yield [!'0'!];
+}
+{% endprettify %}
+
+#### Common fixes
+
+If the return type of the function is correct, then fix the expression
+following the keyword `yield` to return the correct type:
+
+{% prettify dart tag=pre+code %}
+Iterable<int> get zero sync* {
+  yield 0;
+}
+{% endprettify %}
+
+If the expression following the `yield` is correct, then change the return
+type of the function to allow it:
+
+{% prettify dart tag=pre+code %}
+Iterable<String> get zero sync* {
+  yield '0';
+}
+{% endprettify %}
