All the clients have migrated to GridView.  Also, remove RenderGrid,
which isn't needed by GridView.

These widget don't have any clients anymore. Consider using GridView instead.

This widget has no clients. Please use GridView.extent instead.

I see these errors in Atom on my Mac. I'm not sure why they're not being
picked up by the bots.

Overflow handling works with clipping, adding an ellipsis on the last
line, or fading the last line.

Change `Flexible`'s default `FlexFit`

Previously, `Flexible` defaulted to `FlexFit.tight`, which forced the child to
expand to fill the available space. Now, `Flexible` defaults to
`FlexFit.loose`, which does not force the child to expand to fill the available
space.

If you want the child to expand to fill the available space, consider using
`Expanded` instead.

Fixes #5169

Some clients pass null, which was previously allowed by Flexible.

Fixes #7383

Skia calls this BlendMode now and that's a better name.

Fixes #7200

The assert helped me debug an issue recently.

The TODO is obsolete.

Fixes #7252

Fixes #5695

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.

Fixes #6591

This makes https://flutter.io/basic-widgets/#layout-models redundant
with the dartdocs.

Mostly around pointing people towards Block more aggressively.

This is loosely based on the experience of usability study participant P1.

I based this on a conversation I had with @mpcomplete.

Fixes #773

This change might make our grammar less perfect, but it will increase our
sanity.

Previously, we were getting double padding: both inside and outside the button.
This patch moves all the padding inside the button so that the whole region is
hittable and the text is positioned correctly.

Fixes #6059

This widget lets you apply an ImageFit to a child widget.

Fixes #5830

This feature is the implementation of an accessibility feature that changes the
size of text by a constant factor.

Fixes #5873

This property now applies only to the free space in the flex layout (i.e.,
minimize or maximize the amount of free space). Previously, the flexible
children were always allocated a size of zero when MainAxisSize was min. Now
they're allocated the same size that would be if the MainAxisSize was max.
