* Make Tab take a widget as child
This way you can override the semantics information of a Tab (see test).

On iOS 11.0.x ideviceinfo fails with the following message
ERROR: Could not connect to lockdownd, error code -3
This workaround should also work for #12330
libtxt's implementation of Paragraph.getBoxesForRange returns the full line
height for all characters in a line. Blink had been returning a tighter
enclosing rectangle for each individual character.
This patch also makes it possible to create FLX files with no extension.
Previously, the zip tool would add the ".zip" extension if the output file
lacked an extension.
This lets us preview widgets in the gallery using small, normal, large, and HUGE text.
Added selections to the main drawer for these options. Defaults to "normal", obviously.
* Restructure hot mode test so it runs interactively.
This allows to add a benchmark for hot reload after actual source code change.
* Add curly braces, refactory copyRecursive
This modifies the MaterialButton to expand vertically to fit the size of the contained child, no matter what the child widget is. It tries to be as close as possible to the minHeight constraint.
Also updated some doc comments to have headers (extra blank line after first sentence), and to wrap at 80 cols.
Addresses #12311
This reverts commit 5e7bcbacf80875730b2002973b5d82cf5331c2a3.
`flutter run --benchmark` was triggering a different quick bailout path in the VM than `flutter run`. The failure has been fixed upstream.
* Fix restart flow for preview-dart-2 mode.
Restart in preview-dart-2 needs to use kernel file and it has to be complete, rather than incremental kernel file.
* Add curly braces
* Do full compile on restart
* Roll engine to pick up changes to hot reload for preview-dart-2
The initial loading happens on the host, which was building a script snapshot and allowing imports of dart:mirrors. Hot reload happens on the device, which then notices the imports and issues a compile-time error. This change causes programs with imports of dart:mirrors to be rejected during the initial load.

* Keep Icon's subtree structure the same with and without a semanticLabel.
This avoids rebuilding the subtree when a semanticLabel is set/unset.
Also updated some doc comments.
(This is a followup on post-merge comments for #12475)
