java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/**/cache/storage/CAPTURE-20210427_125521.jpg

I am developing a flutter app in which I'm using webview_flutter plugin. Now inside the webview I want upload a file from the device. The problem is when I try to select browse button to choose the files from my device (or use Camera directly), I get IllegalArgumentException.

I found other issues like this but it didn't solve my problem:

  • java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/
  • Android: FileProvider IllegalArgumentException Failed to find configured root that contains /data/data/**/files/Videos/final.mp4
  • FileProvider - IllegalArgumentException: Failed to find configured root

Below is the code for the package I'm using: (You can also go to this LINK to get the exact code which I'm using)
