update win32 dependency to 6.0.0

[ekuleshov]

There is a major update of win32 plugin with significant API updates and it is being picked up by other plugins.

It would be great if the file_picker would use the latest win32 dependency.

Alternatively it might be a good idea to use the filepicker_windows plugin which is maintained by the same folks as win32 plugin and it provides higher level Dart API for native Windows file picker.

I have just started the migration process, as can be seen in #1981. The issue I’m raising here is a support-related one. Win32 version 6 requires Dart 3.11, so Flutter versions older than 3.41 would stop working. On the other hand, should we wait long enough for five versions to be released after 3.41 to take advantage of the changes introduced by Win32 in its latest version? @navaronbracke what do you think?

[vicajilau]

If we wait long enough to ensure that support for the next five versions isn't discontinued, that would mean, according to Google's roadmap, that the changes wouldn't arrive until next year: https://docs.flutter.dev/install/archive#2026-schedule

[navaronbracke]

3.44.0 is the next stable release and is about to land soon. (it includes some unrelated, but important changes to the framework itself)

Maybe we should wait until that version is live? I do agree that this would be disruptive, since file_picker is widely used (we don't know how many people are on what version of the framework, while using our plugin)

[vicajilau]

Until this change can be merged without posing a risk to other users, I will keep the PR and the branch up to date with the master branch.

[ekuleshov]

It will be unfortunately if you are going to wait. I wish the *_plus plugins haven't updated, but they did.

Also most of the platform plugins, including url_launcher and shared_preferences are on much higher versions. 3.9 or 3.10 (the . shorthands). The 3.11 didn't really had anything exiting, not sure why win32 requires that...

environment:
  sdk: ^3.10.0
  flutter: ">=3.35.0"

[halildurmus]

Just a heads up, I’ve published new versions of win32 and win32_registry packages with the minimum SDK lowered to 3.10.

Any chance this could be merged soon? #1981 looks solid, only one test has to be updated.

@ekuleshov @vicajilau can you please share your decision or plan? about when to bump win32 for release, or just NO then wait one mroe year?

[navaronbracke]

We are not going to wait a whole year for this. We plan to do this with Flutter 3.44 in May.

[ekuleshov]

@navaronbracke but why wait til May? Maybe you could at least do a .dev release?

[navaronbracke]

@vicajilau WDYT? Merge the win32 6.0.0 branch into main and release this as 12.0.0-dev?
