The minimum number of pixels for allowing the popover to go downwards. If the downward
available space is less than this, and if the upwards available space is
verticalDiffThreshold
more than the downwards space, the popover will be directed upwards.
Equation:
const directUpwards =
downwardsSpace < minDownSpace &&
upwardsSpace > DownwardsSpace + verticalDiffThreshold;
Supports navigation of the popover via the device-navigation
package.
The number of pixels required for the upwards available space to be bigger than the downwards available space before directing the popover upwards.
Equation:
const directUpwards =
downwardsSpace < minDownSpace &&
upwardsSpace > DownwardsSpace + verticalDiffThreshold;
