getCellCount method

dynamic getCellCount({ required int index, required bool isForCrossAxis, required CollageType type, })

@param index:- index of image. @param isForCrossAxis = if from cross axis count = true Note:- If row == column then crossAxisCount = rowcolumn // rowCount or columnCount e.g. row = 3 and column = 3 then crossAxisCount = 33(9) or 3
