ImageViewer class

A fullscreen image viewer widget with zoom and pan support.

This widget displays an image in fullscreen with a semi-transparent background, a close button, and interactive zoom/pan capabilities.

Usage

Use showImageViewer to display the viewer:

showImageViewer(
  context: context,
  imageFile: File('/path/to/image.png'),
);

Or with a hero animation:

// In your thumbnail widget:
Hero(
  tag: 'my-image',
  child: Image.file(imageFile),
)

// To open fullscreen:
showImageViewer(
  context: context,
  imageFile: imageFile,
  heroTag: 'my-image',
);
