How to deal with " cannot assign a value to final variable"?

[Crabax]

Hello,

I want some help, I'm initiating on Android Studio and I want to do the fololwing:

val infoString = "";
if (!Backend.HasErrors()) {
    for (val budgetPlan : planningInfo) {
        infoString += budgetPlan.getMonth() + "[" + budgetPlan.getNumber() + "]: " + budgetPlan.getDescription();
    }
}

But the compilation is throwing the following:

Error:(62, 17) error: cannot assign a value to final variable infoString

How can I do what I want without specify "String infoString = """?

Thanks in advance

You can't do this with @val. @val expands to "final T", and final means no reassignment, hence the name - val, not var. Perhaps somebody would come with @var proposal but for now it looks like you have to use explicit String instead
