StreamMediaViewer class

A full-screen surface for browsing media (images, videos, etc.).

Composes an optional header, footer, and child media area, and animates the chrome in and out via showChrome. The child is typically a PageView of image / video players, header a StreamAppBar, and footer a StreamBottomAppBar — none are required.

{@tool snippet}

Browse a list of attachments with chrome that hides on tap:

StreamMediaViewer(
  showChrome: _showChrome,
  header: StreamAppBar(title: const Text('Photo')),
  footer: StreamBottomAppBar(title: Text('${i + 1} of $n')),
  child: GestureDetector(
    onTap: () => setState(() => _showChrome = !_showChrome),
    child: PageView.builder(/* ... */),
  ),
)

{@end-tool}
