It's not correct to set sizedByParent for
RenderCustomSingleChildLayoutBox because the delegate's size function
might depend on information other than the incoming constraints.
LayoutCallback passes constraints to the callback, but the constraints
object has a different type for different subclasses. This lets you
call invokeLayoutCallback() with a specific type to verify that
everything is working as expected.
Other changes:
Slightly improve the error reporting in RenderObject.
Allow toStringShallow on RenderObject to have its separator configured.
- more dartdocs for the drag typedefs
- more toStrings to aid debugging
- require the position for DragUpdateDetails since we were omitting it
in some places
- add the primaryVelocity to DragEndDetails so that consumers don't
have to themselves track the axis in question
- fix the velocity tracker so that it doesn't walk the null data.
Previously, near time t=0 (which pretty much only matters in tests,
but it does matter there) we would walk the velocity data and then
also walk missing data, treating it as Point.zero with t=0.
- simplify some of the velocity tracker; e.g. instead of trying (and
failing?) to clear the velocity tracker when the pointer stalls,
just drop the data before a stall during the velocity estimation
(where we redundantly had another bigger horizon anyway).
This patch replaces uses of Flexible with Expanded where we're using
FlexFit.tight. We still need to think of a better name for the
FlexFit.loose variant.
Also, improve the docs for Row, Column, Flex, and RenderFlex to be more
problem-oriented and to give a complete account of the layout algorithn.

More idiomatic use of constraints in performResize.
Trivial fixes to comments.
Make ProxyBox not use BoxParentData since it ignores the field.
Make applyPaintTransform more helpful if you use a different ParentData
subclass than RenderBox expects.
Make debugAssertIsValid actually fulfill its contract in RenderObject as
documented.
Add a childBefore for symmetry (we already had childAfter).
Fix the way we dump the child list when there's no children in a
multichild render object.
More asserts in the rendering test library.
If maxLines is 1, it's a single line Input that scrolls horizontally.
Otherwise, overflowed text wraps and scrolls vertically, taking up at
most `maxLines`.
Also fixed scrolling behavior so that the Input scrolls ensuring the
cursor is always visible.

When not dismissing, the Dismissable widget should cull its background.
When a dismiss is in progress, it should clip the background to just the
part that is revealed.

We weren't computing the bounds for composited transforms correctly. We
need to conjugate the transform by the offset in order to get the
correct paint bounds for the composited layer. We now also use the same
math in the non-composited case for consistency.
Also, don't scale the z-coordinate in RenderFittedBox.
Fixes#6293
