Overview
The secure_app_switcher package enhances app privacy by applying a masking effect to the app's screen preview in the device's app switcher or task list. This prevents sensitive content from being visible when users swipe through open apps, offering an extra layer of security on Android and iOS devices. The package integrates seamlessly into Flutter applications with minimal configuration, ensuring that the app’s visual state remains hidden during multitasking. It is particularly useful for apps handling confidential data such as banking, healthcare, or messaging platforms.
