Code folding for `switch` statements

[stereotype441]

With the addition of patterns to the Dart language, it would be nice if code folding could be used on switch statements, much as it can be used for other control flow such as if statements.

For example, given the code:

switch (expr) {
  case 0:
    statement;
    statement;
    statement;
  case 1:
    statement;
    statement;
    statement;
}

It would be nice to be able to collapse individual cases, e.g.

switch (expr) {
  case 0: …
  case 1:
    statement;
    statement;
    statement;
}

Or to collapse the entire switch statement:

switch (expr) {…
}

This landed in dart-lang/sdk@528c75a. It's entirely a language server change so will show up with a new SDK release and doesn't require an extension update.

not working for me at VScode, using latest version of the SDK @DanTup

@Fernandomr88 the change was made after the branch for the last SDK (Dart 3.0), so it will show up in a future SDK release (3.1, etc.). It should be available on beta/dev/master channels already.

sorry for my mistake @DanTup, hadn't noticed that "tiny" detail lol, looking forward for that release

np! FWIW I did just test it in latest code to verify, and it does seem to work as you'd expect :)

@DanTup hey Dan, any hint on when this will be released?

@Fernandomr88 this change shipped in Dart 3.1 / Flutter 3.13. It seems to work in my testing:

folding.mp4

If you have code where it doesn't work, could you file a new issue with an explicit (complete) code sample so I can test with it? Please also include your exact SDK version.

Thanks!

Hey @DanTup , it worked indeed. Sorry for the mess, I was commuting and remembered this and asked 🫠
