You can’t set a Collin Tree listview with a String, it requires a multi-leveled List.

Bro help me,
I want some help, If you are free then please help me.

Now I’m making an app that contains dynamic links of PDF files, But problem is when I try to open the file using extended web view extension this will download PDF File every time in phone.
I want to download one time only (If file exists then without download file opens automatically).

I hope you will help me I don’t get any solution from any where.
