[BUG] Null check operator used on a null value - version 0.30.0

[darkh]

Describe the bug
I am using stream to rebuild the widget whenever I got new data, every time new data coming the console throw the follow error but the app not crashing and the data showing right it's just the error show in the console

this error didn't appear when I used older version it's start only when switched to flutter 2

seems the error happens on this line
childParentData.offset = badgeOffsets[counter++]! - sizeOffset;

I don't use the badge on my code
