flutter_screenshot_blocker changelog

1.0.1 #

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

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.

Fixed — ScreenshotEvent metadata type crash on Android: platform channel delivers nested maps as Map<Object?, Object?>. Replaced lazy .cast<String, dynamic>() (which caused type '_Map<Object?, Object?>' is not a subtype of type 'Map<String, dynamic>?' at runtime) with Map<String, dynamic>.from(meta) which eagerly creates a properly-typed copy.
Docs — Added Android Emulator limitation section to README: FLAG_SECURE blocks system-level captures (ADB, Android Studio) but host OS screenshots bypass it; real device recommended for full testing.
Docs — Improved all usage sections: added import statement, ScreenshotEvent model reference, setSecureFlag and isScreenshotBlockingEnabled examples, platform requirements table, and expanded Troubleshooting section.
