    The error you share in the image tells what is the problem. You are trying to assign a function that has the incorrect types to what the parameter expects.

    void Function(TapDownDetails) is different than void Function(TapDragDownDetails)?.

    You should assign to the parameter a function with same argument type of TapDragDownDetails and that function should also be nullable.
