handleOpBeforeCalculate method Null safety

void handleOpBeforeCalculate(
  1. Model<ProgramOperation> m,
  2. void opBeforeCalculate(
      )
    )

    Execute the beforeCalculate function of the operation. Normally it just executes, but some 15C operations can be deferred; this method can be overridden to do that.

    Implementation

    void handleOpBeforeCalculate(Model m, void Function() opBeforeCalculate) =>
    opBeforeCalculate();
