device_io 2.0.0-dev.0

Cross-platform file picking, saving, sharing, and opening for Flutter. Image and file pickers, save dialogs, OS share sheet, open-with — one API on mobile, desktop, and web.

Changelog — prerelease lane

2.0.0-dev.0

• Breaking: the result family is renamed — PlatformResult → Outcome, PlatformSuccess → Success, PlatformCancelled → Cancelled, PlatformUnsupported → Unsupported, PlatformFailure → Failed, PlatformPermissionDenied → PermissionDenied. Migration is a mechanical find-and-replace of those six names; fields, semantics, and the sealed hierarchy (PermissionDenied still subtypes Failed) are unchanged.
• Added AssetPicker.pickDirectory — a directory chooser on the five native platforms; Unsupported on web.
• Added FileSaver.saveInto — silent save into a caller-chosen directory (pairs with pickDirectory for pick-once-save-many), with the same name-sanitizing and no-clobber guarantees as save; Unsupported on web.
• Added FileOpener.open(SaveLocation) — opens what a save returned without destructuring: SavedAtPath opens at its path, SavedByBrowser returns Unsupported.
