Inlay hints not shown on collection control statements

[water-mizuu]

Describe the bug
When var is used in a for loop inside a collection, it doesn't show the type of the object.

To Reproduce
Paste this code into any function:

var objects = ["1"];
var objects2 = [for (var i in objects) i];

Expected behavior

var List<String> objects = <String>["1"];
var List<String> objects2 = <String>[for (var String i in objects) i];

Thanks! Working on a fix at https://dart-review.googlesource.com/c/sdk/+/340880.

Fixed by dart-lang/sdk@367b8fd. Will show up in a future Dart SDK release (not a Dart-Code extension release).
