Dart's system requirements currently state that only Windows 10 & 11 are supported. However, we don't currently prevent the dart tool and the Dart VM from running on Windows 7 & 8, as a few Flutter customers were still using that support. The Flutter team is now considering increasing their minimum to Windows 10, so with that, we can go ahead and fully de-support Windows 7 & 8 in Dart too. See the linked Flutter issue for more details.

Work items

Once we've de-supported these older versions, we can take some steps to further clean up our code base:

• Announce on Dart Announce
• Put in a check for min Windows 10 when the VM runs, and exit if not
• Reland fix for vm crash Platform.localHostname Chinese Windows
• Clean up unwinding record dynamic loading of Windows API functions introduced in Windows 8.
• Remove IsWindows10OrGreater check in https://github.com/dart-lang/sdk/blob/main/runtime/bin/eventhandler_win.cc#L155
