isExpanded

it would have been very helpfull if we get any variable somethjing like isExpanded to keep it open when we need it to initially open like how normal dropdown works

Hey @darshan-cn-5
For this purpose, you can pass the OverlayPortalController to dropdown and use the method overlayController.show(). If you want to open the dropdown on your screen widget initialization, you have to use the WidgetsBinding.instance.addPostFrameCallback and call the .show() method inside otherwise you'll get rendering issues.
But yeah, good suggestion. I'll add the isExpanded property in the future release!
