Can we use the PHP view that single quotes don't contain variables, but double quotes do... this may help the parser in speed, but more importantly it means the programmer doesn't have to check for and escape variables in single quoted strings.

Dart already has raw strings: @­"This $foo isn't interpolated".


Added WontFix label.

See: b/374689139.

https://dart-review.googlesource.com/c/sdk/+/390941 is blocking an SDK roll.

Root cause:


```
Action threw an exception: type 'ConstructorMember' is not a subtype of type 'ConstructorFragment' in type cast
#0      InterfaceTypeImpl.constructors2.<anonymous closure> (package:analyzer/src/dart/element/type.dart:569)
#1      MappedListIterable.elementAt (dart:_internal/iterable.dart:435)
#2      ListIterator.moveNext (dart:_internal/iterable.dart:364)
#3      new _GrowableList._ofEfficientLengthIterable (dart:core-patch/growable_array.dart:189)
#4      new _GrowableList.of (dart:core-patch/growable_array.dart:150)
#5      new List.of (dart:core-patch/array_patch.dart:39)
#6      ListIterable.toList (dart:_internal/iterable.dart:224)
#7      InterfaceTypeImpl.constructors2 (package:analyzer/src/dart/element/type.dart:570)
#8      _Visitor._hasConstConstructorInvocation (package:linter/src/rules/prefer_const_constructors_in_immutables.dart:110)
#9      _Visitor.visitConstructorDeclaration (package:linter/src/rules/prefer_const_constructors_in_immutables.dart:58)
```


To verify the fix locally:

```
  solo_test_X() async {
    await assertNoErrorsInCode(r'''
class A<T> {}
''');

    var A = findElement.class_('A').instantiate(
      typeArguments: [intType],
      nullabilitySuffix: NullabilitySuffix.none,
    );
    A.constructors2;
  }
```
