I show a DraggableScrollableSheet with initialChildSize: .5 via showModalBottomSheet. While the sheet is "expanded" to its full extent, animating (animateTo(.5)) or resetting (reset()) the sheet with a DraggableScrollableController causes the sheet to close instead of stopping at .5
Steps to Reproduce
Execute flutter run on the code sample
Tap the "show modal" button
Either drag the sheet upwards or tap the "ANIMATE TO 1" button in order to open the sheet to its full extent
Now tap "RESET": you will see that the sheet gets closed instead of being reset to its initialChildSize (.5)
Retry the step 3. and then tap "ANIMATE TO .5", you will see that the sheet animates to .5 but shortly after it gets closed.
Thanks for the report. Seeing same behavior as reported using latest versions.
stable, master flutter doctor -v
