cGetGridRatio function

double cGetGridRatio(
  1. {required BuildContext context,
  2. required int crossAxisCount,
  3. required int height,
  4. required int width,
  5. bool logData = false,
  6. double? discardSize}

Calculate the childAspectRatio for a GridView based on item dimensions and crossAxisCount.

This function calculates the childAspectRatio for a GridView based on the provided height, width, and crossAxisCount of the grid items. It takes into account the available screen width (context.cWidth) and an optional discardSize that can be used to exclude additional space.


  • context: The BuildContext used to access the screen width.
  • crossAxisCount: The number of items in the cross-axis of the GridView.
  • height: The height of each grid item.
  • width: The width of each grid item.
  • logData: (Optional) Set to true to log the calculated aspect ratio.
  • discardSize: (Optional) An additional size to be excluded from the width calculation.

Returns the calculated childAspectRatio as a double.


double cGetGridRatio({
  required BuildContext context,
  required int crossAxisCount,
  required int height,
  required int width,
  bool logData = false,
  double? discardSize,
}) {
  double primaryWidth = ((context.cWidth) - (discardSize ?? 0.0));
  double w = (primaryWidth / crossAxisCount);
  double h = (primaryWidth / (primaryWidth / width));
  double asr = w / (h - (width - height));
  if (logData) {
    cLog('GridAspectRatio => $asr');
  return asr;
