I am working on a flutter app. I have a dropdownbutton on the appbar. There is a search bar next to it, so I don't want it to take too much space when it isn't open. I want it to take as much space as possible when it is opened.

I expect it to act as shown in the links below. Sorry, stack overflow won't allow me to include the images here. not open open

  • Thank you for the welcoming. I am a newbie here. I wanted to replicate what I have done on native android ( The app shown in the links to the images) using flutter. I couldn't find a way to give the drop down items full width only when they are listed( not in condensed mode). – Nahom Negussie Jul 12 '19 at 07:19

  • This is a really nice approach! It can make the popup different, but for some reason it is not enabling me to give the popup a greater width than the collapsed one. – Nahom Negussie Jul 18 '19 at 08:21
  • Hmm, I would inspect up the tree and see what's forcing the width and see if I can modify it for the two case... – Gazihan Alankus Jul 18 '19 at 12:53
