`Bind all parameters to fields` appears twice, mangles up code and places caret at wrong position

[denniskaselow]

Using Dart SDK version: 3.11.0-190.0.dev (dev) (Mon Dec 1 04:03:43 2025 -0800) on "windows_x64"

The following code:

class Foo {
  Foo({required int foo, required int foobar});
}

shows two assists, both named "Bind all parameters to fields". with the second one only binding one parameter to a field.

But it looks like an assist with a correct text ("Bind parameter to field") exists:

sdk/pkg/analysis_server/lib/src/services/correction/assist.dart

Lines 39 to 48 in a5fe41a

	static const bindAllToFields = AssistKind(
	'dart.assist.bindAllToFields',
	DartAssistKindPriority.default_,
	'Bind all parameters to fields',
	);
	static const bindToField = AssistKind(
	'dart.assist.bindToField',
	DartAssistKindPriority.default_,
	'Bind parameter to field',
	);

Furthermore, selecting the second assist on foo, creates this:

The placeholder-thingies where I can enter a different type or name are misplaced.

If I select the first "Bind all parameters to fields" assist, it creates this abomination:

class Foo {
  Foo({required this.foo, required this.bar});

is.nar}oo;

  int bar;
}

More parameters create a greater mess.

Thanks a lot for the great bug report! That does look messy.
