Warning: Tried to initialize from a previous compilation (build/app.dill.track.dill), but the file was not self-contained. This might be a bug.

Dart VM version: 2.3.0-dev.0.0.flutter-8e73b3c006 (Tue Apr 16 21:29:55 2019 +0000) on "macos_x64"

Ran a flutter app on iOS Simulator with success, but got this warning:

Warning: Tried to initialize from a previous compilation (build/app.dill.track.dill), but the file was not self-contained. This might be a bug.

The Dart team would greatly appreciate it if you would take a moment to report this problem at http://dartbug.com/new.
If you are comfortable with it, it would improve the chances of fixing any bug if you included the file file:///var/folders/l3/rjc6f8297x957mfyvyt0pntr0045mq/T/initialize_from.dill7VrvaI/initialize_from.dill.gz in your error report, but be aware that this file includes your source code.
Either way, you should probably delete the file so it doesn't use unnecessary disk space.```
