GetResource into IOS Textarea

I have dragged a text file into the TextCopyFiles space. How do I get the contents of that resource directly into an IOS Textarea?
I seem to know everything about ‘f’ except its contents

Dim f As FolderItem
f = SpecialFolder.GetResource(“AboutSC.txt”)

if f <> nil then
TextArea1.Text = ???
else
TextArea1.Text = “File Missing”
end if

dim a as Text
Var f As FolderItem = SpecialFolder.GetResource(“AboutSC.txt”)
if f <> nil then
Dim textInput As TextInputStream
textInput = xojo.io.TextInputStream.Open(f,TextEncoding.UTF8)
a = textInput.ReadAll
textInput.Close
TextArea1.Text = a
else
TextArea1.Text = “File Missing”
end if
