Issues with quick fix for `sort_constructors_first` lint rule

[gryznar]

1. Spacing

class Foo {
  final String foo;

  const Foo({required this.foo});
}

after applying quick fix:

class Foo {

  const Foo({required this.foo});
  final String foo;
}

expected:

class Foo {
  const Foo({required this.foo});

  final String foo;
}

• no blank space between signature and constructor
• space between constructor and field?

2. Enum:

enum Foo {
  bar('Open'),
  baz('Accepted Provisionally'),

  final String value;

  const Foo(this.value);
}

after applying nothing happens despite analyzer properly emits warning. Expected:

enum Foo {
  bar('Open'),
  baz('Accepted Provisionally'),

  const Foo(this.value);

  final String value;
}
