wrapWithDisplayAreaSizeProvider property
Wrap the form with a DisplayAreaSizeProvider.
The dialog form requires the DisplayAreaSize to calculate the height of the scroll view port. This value should be provided from a parent widget that has access to the size of the display area. If the form is dynamically sized then the provider needs to set at a higher level in the widget tree and this value should be set to false.
Implementation
final bool wrapWithDisplayAreaSizeProvider;
