flutter_future_progress_dialog 2.0.0

Show a progress dialog while a Future runs and return the result. Supports Material, Cupertino, and adaptive styles with type-safe error handling.

2.0.0

Breaking changes

• ProgressDialogResult gained a third variant, Cancelled<T>. The type is sealed, so exhaustive switch statements over a result need a Cancelled case added. See "Migrating from 1.x" in the README
• showAdaptiveProgressDialog now selects its style from Theme.of(context).platform instead of the host operating system, matching Flutter's own showAdaptiveDialog. An app that sets ThemeData(platform: ...) now gets the style it asked for rather than the style of the machine it runs on

Added

• Flutter Web support — flutter_future_progress_dialog no longer imports dart:io, so pub.dev now reports all six platforms
• Cancelled<T> result variant, the isCancelled getter, and ProgressDialogResult.cancelled()
• ProgressDialogCancelledException, thrown by unwrap() on a cancelled result

Fixed

• "Null check operator used on a null value" crash when the dialog was dismissed before the task completed — by the Android back button, or by a custom builder calling Navigator.pop
• The returned future never completing when the hosting Navigator was disposed while the task was in flight, which left the caller awaiting forever. The call now settles with Cancelled
• map() and flatMap() now pass cancellation through instead of failing to compile against the widened result type

Notes

• Cancellation dismisses the dialog, not the task. Dart futures cannot be cancelled, so the work runs to completion in the background and its result is discarded
