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) {…
}
