1.0.1 #

  • Initial release — Flutter plugin that prevents screenshots or shows black screen when screenshots are taken using system-level protection.

1.0.2 #

  • Updated README with usage examples and platform setup instructions.

1.0.3 #

  • iOS — Fixed EXC_BAD_ACCESS crashes caused by moving window.layer out of the screen layer hierarchy, which violated UIKit's internal invariants and caused objc_msgSend / objc_retain faults.
  • iOS — Rewrote screenshot blocking mechanism: instead of reparenting window.layer, only flutterView.layer (Flutter's root view layer) is reparented into the UITextField's protected IOSurface subtree. window.layer now stays untouched.
  • iOS — Fixed sublayer index selection: uses sublayers.last on iOS 17+ / iOS 26 (UITextField redesign moved the protected IOSurface layer to the last sublayer position) and sublayers.first on iOS ≤ 16.
  • iOS — Screen recording overlay: shows a solid black UIWindow at a high window level when screen recording is active, without touching Flutter's window or layer hierarchy.
  • iOS — Fixed Dart type error: nested metadata map from the platform channel now correctly cast with .cast<String, dynamic>().
  • iOS — Swift version bumped to 5.3 in podspec for compatibility.
  • Docs — Added iOS Simulator limitation section to README: screenshot blocking requires a real iOS device; the IOSurface hardware protection flag is not emulated in the Simulator.
