next method

@override Future<void> next({ bool waitCurrentEnd = true, bool currentEndWithAnimation = true, FutureCallback? onCurrentEndComplete, })

waitCurrentEnd - 是否等待當前步驟關閉後再跳下個步驟 currentEndWithAnimation - 關閉當前步驟是否有動畫 onCurrentEndComplete - 當前步驟完全關閉後回調

Implementation

@override
Future<void> next({
  bool waitCurrentEnd = true,
  bool currentEndWithAnimation = true,
  FutureCallback? onCurrentEndComplete,

    nextStep = getTargetRectGetter(_currentStepIndex + 1);
  }
