I wanted to create a slightly different appbar style for a new page route that animated in from bottom. The UX would give the sense of dismissing the page, rather than navigating back a page, and the AppBar would be reminiscent of iOS styling. The title property of the AppBar takes a widget and was my best bet since we can make the widget anything we want. I was trying to use only the ‘title’ property and assumed it would just ‘do the right thing’ by expanding to be full width.

I ran into an issue with flutter losing the connection to my iOS device this morning after doing a fresh install of MacOS Mojave over the weekend. It was really annoying and was creating a huge lag time in development. It turns out there’s a bug in libusbmuxd, a client library to multiplex connections to/from iOS devices. Instead of waiting for a patch, I was able to revert to an older commit.
