Dynamically call function
with the specified arguments.
Acts the same as calling function with positional arguments corresponding to the elements of positionalArguments
and named arguments corresponding to the elements of namedArguments
.
This includes giving the same errors if function
isn't callable or if it expects different parameters.
Example:
Function.apply(foo, [1,2,3], {#f: 4, #g: 5});
gives exactly the same result as
foo(1, 2, 3, f: 4, g: 5).
If positionalArguments
is null, it's considered an empty list. If namedArguments
is omitted or null, it is considered an empty map.
external static apply(Function function, List positionalArguments, [Map<Symbol, dynamic> namedArguments]);
