Writing to text file in app inventor

After continuous search on google, I still can't seem to figure out this problem with app inventor 2. My question is how can I write to text file as initial value without user input. For example I want to store '6' as the initial value in a text file, there are ways to do it by clicking on button but is there a way to store the initial value without getting the user to enter a value? Also would this value be available each time the app is run? or would I need to set the initial value each time?

Many Thanks in advace

  • is there a way to store the initial value without getting the user to enter a value?

    Normally you would use a variable to store an initial value. You do not have to store that in a file! But if you like to use a file, you can use the Screen.Initialize event

    enter image description here

    see also the documentation of the File component

    Also would this value be available each time the app is run?

    yes, but only if the user did not delete the file manually...

    or would I need to set the initial value each time?
