      // Slack's content URI is currently content://com.Slack.fileprovider/... form and the most problematic issue
      // with the URI is capitalized `S` inside the host name; Dart's Uri class will make the host name lower-case
      // and the resulting URI can not be resolved with Content Resolver any longer :(
      // Possible, but dirty workaround might be replacing these host names on your code.
