Usage

With HyperViewer

import 'package:hyper_render/hyper_render.dart';
import 'package:hyper_render_clipboard/hyper_render_clipboard.dart';

final clipboard = SuperClipboardHandler();

HyperViewer(
  html: '<img src="https://example.com/photo.jpg">',
  // HyperViewer has no clipboard parameter: hand images to HyperImage yourself.
  widgetBuilder: (node) {
    if (node is AtomicNode && node.tagName == 'img' && node.src != null) {
      return HyperImage(
        src: node.src!,
        width: node.intrinsicWidth ?? node.style.width,
        height: node.intrinsicHeight ?? node.style.height,
        clipboardHandler: clipboard,
      );
    }
    return null; // everything else renders as usual
  },
)

Long-pressing a HyperImage shows Copy / Save / Share. Without a clipboardHandler the built-in images offer URL copy only.

Standalone

final handler = SuperClipboardHandler();

await handler.copyImageFromUrl('https://example.com/photo.jpg');

final path = await handler.saveImageFromUrl(
  'https://example.com/photo.jpg',
  filename: 'my_photo.jpg',
);

await handler.shareImageFromUrl(
  'https://example.com/photo.jpg',
  text: 'Check this out!',
);

From bytes

final Uint8List imageBytes = ...;

await handler.copyImageBytes(imageBytes, mimeType: 'image/png');
await handler.saveImageBytes(imageBytes, filename: 'screenshot.png');
await handler.shareImageBytes(imageBytes, text: 'Created with MyApp!');
