applyOverlayMode function

Future<void> applyOverlayMode(OverlayMode mode, { double blurRadius = 30.0, int color = 0xFF000000, })

Applies the given mode using the idempotent NoScreenshot API.

• none re-enables screenshots (no protection).
• secure blocks screenshots and screen recording.
• blur shows a blur overlay in the app switcher.
• color shows a solid color overlay in the app switcher.
• image shows a custom image overlay in the app switcher.

Implementation

Future<void> applyOverlayMode(
  OverlayMode mode, {
  double blurRadius = 30.0,
  int color = 0xFF000000,
}) async {
  final noScreenshot = NoScreenshot.instance;
  switch (mode) {
    case OverlayMode.none:
      await noScreenshot.screenshotOn();
    case OverlayMode.secure:
      await noScreenshot.screenshotOff();
    case OverlayMode.blur:
      await noScreenshot.screenshotWithBlur(blurRadius: blurRadius);
    case OverlayMode.color:
      await noScreenshot.screenshotWithColor(color: color);
    case OverlayMode.image:
      await noScreenshot.screenshotWithImage();
  }
}
