FactoryFuncParam<T, P1, P2> typedef

FactoryFuncParam<T, P1, P2> = T Function(P1 param1, P2 param2)

For Factories that expect up to two parameters if you need only one use void for the one you don't use

Implementation

typedef FactoryFuncParam<T, P1, P2> = T Function(
  P1 param1,
  P2 param2,
);
