Description
Steps to reproduce by spamming right click during drag (one of two ways to see bug appear):
- try to drag a widget with the left button but also tapping the right mouse button at the same time If the drag works as expected, reattempt the same drag until it the freeze happens, typically within about 10-20 attempts
- When the widget freezes, and it’s in debug mode, an assert gets printed that comes from the flutter engine and gets printed in the console (see assert exception thrown below)
Here is exception that throws in the flutter/dart engine:
