Breakpoints crash flutter application #19379
Description
Observed on master building from a mac for either an android device or iOS simulator. Insert a debugger() call somewhere (I used the update methods in editable_text.dart) or use the observatory break x command. When the breakpoint is hit the application crashes immediately.
Android:
