arg

A utility builder to be used with fcl.args[...] to create FCL supported arguments for interactions.

Arguments are used to pass data to Cadence scripts and transactions. The arguments must match the number and order declared in the Cadence script. This function creates an ArgumentObject that holds the value and type passed in.
