The minimum number of pixels for allowing the pop-up 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 pop-up will be directed upwards.
Equation:
const directUpwards =
downwardsSpace < minDownSpace &&
upwardsSpace > DownwardsSpace + verticalDiffThreshold;
Supports navigation of the pop up 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 pop-up upwards.
Equation:
const directUpwards =
downwardsSpace < minDownSpace &&
upwardsSpace > DownwardsSpace + verticalDiffThreshold;
Options for PopUpManager.
