推荐答案

这是已知问题( Flutter WebView blob pdf下载.我已经更新了答案，以支持依赖于blob具有的mimeType的扩展，而不是针对.pdf对其进行硬编码.你可以试试看.您将需要映射获得的mimeType，例如 application/vnd.ms-excel 到 .xlsx 等.

It is known issue (Download Blob file from Website inside Android WebViewClient). There is another question about .pdf files with exactly the same problem Flutter WebView blob pdf download. I have updated my answer to support extension that depends on mimeType that blob has instead of hardcoding it for .pdf. You can try it. You would need to map the mimeType that you get e.g. application/vnd.ms-excel to .xlsx etc.
