How to use Variables in MIT App Inventor 2 [ With Example]
Variable, Creates a value that can be changed while an app is running, and gives that value a name. Variables are global in scope, which means you can refer to them from any code in the app, including from within procedures. When you create a new variable block, App Inventor chooses a unique name automatically. Local Variable A local variable is a variable that is declared within a function or it is an argument passed into a function. This means that you can only access these variables in that specific function where they are declared or passed in as an argument. Local variables are created when: arguments are passed in to a procedure or event using the initialize local name to block using a for each in list or for each from to block (these for loops will create a local variable for the letter.
