BreakingUpgrade verdict

8 breaking changes.

In plain terms
  • Method and property names on COM and WinRT objects now start with a lowercase letter, matching Dart style and avoiding name clashes.
  • If you used fromPointer on WinRT classes, it is now called fromRawPointer.
  • If you import the WinSock library directly, struct names are now all uppercase, so old names like hostent must be updated.
  • The TouchInputParameters struct is now named in all uppercase, so references to it must be updated.
