screen_lock_plugin 0.0.3

A Flutter plugin that allows you to lock the Android device screen programmatically using Device Admin permissions.

0.0.3

• Screen on/off events are now delivered by a dedicated foreground service (ScreenEventService) so they keep firing when the host app is backgrounded or running under background / FGS restrictions
• Multi-source screen state detection: ACTION_SCREEN_ON / ACTION_SCREEN_OFF broadcasts + DisplayManager display-state changes + a PowerManager.isInteractive polling fallback, de-duplicated into a single event stream
• Adaptive foreground service type on Android 14+: systemExempted when the app is the device owner (kiosk), specialUse otherwise, with the required PROPERTY_SPECIAL_USE_FGS_SUBTYPE declared in the manifest
• Persistent low-importance notification ("Screen monitor active") keeps the monitoring service alive
• New Android permissions declared: FOREGROUND_SERVICE, FOREGROUND_SERVICE_SPECIAL_USE, FOREGROUND_SERVICE_SYSTEM_EXEMPTED, POST_NOTIFICATIONS
• Errors starting the foreground service are now surfaced on the event stream as FGS_START_FAILED instead of being silently dropped
• Example app: request POST_NOTIFICATIONS on startup, show notification permission status, and tap the "Last screen event" label to see the last 10 events with timestamps
