[macOS][Desktop]: Entering a compound character crashes Mac app #104578
Description
I'm working on IME support for Super Editor. At the moment, if I try to enter a ü in an empty paragraph, the entire Mac app crashes.
It's likely that this problem is the result of something that we're doing in Super Editor, however, I'm thinking that shouldn't be possible to completely crash the app. So something should probably be updated on the Flutter side, too.
The key presses to generate a ü are:
- opt+u
- u
Here's a snippet from the Mac crash report that results from this crash:
