Can not fetch image of some link like ChatGPT or TikTok

[harrynguyenangle]

There's some issue that the data from LinkPreview can not fetch image from link like ChatGPT or TikTok, but works well some common link like Google, YouTube, Drive, StackOverFlow, etc

LinkPreview(
              enableAnimation: true,
              onPreviewDataFetched: (data) => setPreviewDataURL(data),
              previewData: previewURLdata, // Pass the preview data from the state
              text: urlString,
              width: widget.width,
              previewBuilder: (p0, p1) {
                return Column(
                  children: [
                    // IMAGE
                    if (p1.image != null)
                      Container(
                          height: 100,
                          width: widget.width + 4,
                          margin: const EdgeInsets.fromLTRB(1, 1, 1, 10),
                          child: ClipRRect(
                            borderRadius: const BorderRadius.only(
                              topLeft: Radius.circular(15),
                              topRight: Radius.circular(15),
                            ),
                            child: Image.network(p1.image!.url, fit: BoxFit.cover),
                          )),

                    // TITLE
                    if (p1.title != null)
                      Container(
                          margin: const EdgeInsets.only(left: 10, right: 10, top: 5),
                          child: Text(p1.title!,
                              maxLines: 3, style: TextStyle(fontWeight: FontWeight.w600, color: widget.titleColor))),

                    // URL
                    if (p1.link != null)
                      Container(
                        margin: const EdgeInsets.only(left: 10, right: 10, bottom: 8),
                        child: Text(
                          p1.link!,
                          overflow: TextOverflow.ellipsis,
                          maxLines: 1,
                          style: TextStyle(
                            color: widget.urlColor,
                          ),
                        ),
                      )
                  ],
                );
              }),```

Yeah it won't work for everything, sometimes frontend is blocked from reading link metadata. If you want a robust solution that will work for everything, you need a backend solution, something like https://www.linkpreview.net or similar
