# apply method Null safety

dynamic apply (

1. Function function,
2. List? positionalArguments,
3. [Map<Symbol, dynamic>? namedArguments]

)

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.

## Implementation

    external static apply(Function function, List<dynamic>? positionalArguments,
        [Map<Symbol, dynamic>? namedArguments]);
