Assertion when leaving Screen that is scrolled all the way down
I get the following assertion, when i leave a screen, that is scrolled all the way down:
I/flutter ( 3660): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
I/flutter ( 3660): The following assertion was thrown during performLayout():
I/flutter ( 3660): Build scheduled during frame.
I/flutter ( 3660): While the widget tree was being built, laid out, and painted, a new frame was scheduled to rebuild
I/flutter ( 3660): the widget tree. This might be because setState() was called from a layout or paint callback. If a
I/flutter ( 3660): change is needed to the widget tree, it should be applied as the tree is being built. Scheduling a
I/flutter ( 3660): change for the subsequent frame instead results in an interface that lags behind by one frame. If
I/flutter ( 3660): this was done to make your build dependent on a size measured at layout time, consider using a
I/flutter ( 3660): LayoutBuilder, CustomSingleChildLayout, or CustomMultiChildLayout. If, on the other hand, the one
I/flutter ( 3660): frame delay is the desired effect, for example because this is an animation, consider scheduling the
I/flutter ( 3660): frame in a post-frame callback using SchedulerBinding.addPostFrameCallback or using an
I/flutter ( 3660): AnimationController to trigger the animation.
