ReadonlyconfigThe key of the parameter's config in the build's params map.

Readonlytype
One parameter as the app reads it: its specifier, the key of the config its field lives in (the build's params map names the config by index; the answer by this key) and the app's built-in default.
int64values are JavaScript numbers: no answer the Simulator has met carries one outside the safe-integer range (the largest is1253480966013273), and an answer that does is refused when it is stored rather than rounded.
