Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The screenshot_callback package is a Flutter plugin that enables detection of mobile screenshots on both Android and iOS devices. It triggers callback functions when a screenshot is taken, allowing developers to respond dynamically—such as by pausing sensitive content or logging events. Built for cross-platform compatibility, it integrates seamlessly into existing Flutter apps without requiring native code changes. The plugin leverages platform-specific APIs to monitor screenshot activity efficiently and reliably.

Use cases

  • Detecting when users take screenshots in sensitive apps
  • Triggering security measures upon screenshot detection
  • Logging screenshot events for analytics
  • Preventing unauthorized screen captures
  • Enabling responsive UI adjustments after screenshots

Key features

  • Cross-platform support for Android and iOS
  • Simple callback execution on screenshot detection
  • Minimal setup with pub add command
  • Secure and lightweight implementation
  • No need for native code modification

Suitable for

  • Apps requiring screenshot protection
  • Security-focused applications
  • Educational or exam-like environments
  • Content providers needing usage tracking
  • Developers building privacy-aware features

Considerations

  • Requires appropriate permissions on Android
  • Limited to detecting screenshots, not preventing them
  • May not work on all device models or OS versions
  • Behavior can vary between iOS and Android
  • Does not guarantee 100% detection accuracy across all scenarios
