Need Row Value in filterFunction. (As of Now only Cell value)

How to get entire row value inside a filterFunction (Similar to valuePrepareFunction(cell,row)).

valuePrepareFunction : (cell,row) => {
return this.timeDifference.transform(row.reserveTime, row.releaseAt);
},
filterFunction : (cell, search, **row**) => {
let temp = new Date(cell).toDateString() + ' - ' + new Date(cell).toLocaleTimeString();
if (String(this.timeDifference.transform(**row.reserveTime**, **row.releaseAt**)).toLowerCase().includes(search.toLowerCase()) || search === '') {
return true;
} else {
return false;
}
}

Here i am finding the difference of two date using valuePrepare function and displaying them as duration. On filter i need to filter based on the same value.To calculate i need entire row data instead of cell value.
