link_preview #

Flutter plugin for previewing links (such as title, description, image). This is a port of Android and iOS library. For now, it is not recommended to use this plugin in production.

Usage #

Future<void> getLinks() async {
      try {
            PreviewResponse previewResponse = await LinkPreview.getPreview('https://google.com');
            _previewData(previewResponse);
      
            PreviewResponse previewResponse2 = await LinkPreview.getPreview('https://facebook.com');
            _previewData(previewResponse2);
      
            PreviewResponse previewResponse3 = await LinkPreview.getPreview('https://amazon.com');
            _previewData(previewResponse3);
          } on PlatformException {
            print('Error occured!!');
          }
  }

  _previewData(PreviewResponse previewResponse) {
    if (previewResponse.status == PreviewStatus.success) {
          print('===============================================');
          print('Received status: ${previewResponse.status}');
