This patch includes a number of improvements:
* Material page routes now put a repaint boundary inside their transition so
they don't repaint during the transition.
* Heroes that are on a quest now get a repaint boundary so we repaint them
individually.
* I've hoisted the transparent material for the product items up in the widget
tree, which doesn't affect performance but makes the ink splashes reach the
edge of the product cards.
* I've changed the repaint rainbow visualization to make it easier to see
what's going on.
Previously, we considered them one operation in the compositor, which didn't
trigger caching. Now we have a way to explicitly hint that the compositor
should cache a layer.
This makes the about page show the licenses of all the Dart packages that a Flutter app uses.
Issues that this does not yet resolve:
- I'm still working on getting the full list of licenses for the sky_engine package.
- Some of the licenses don't print very readably.
- There's no scrollbar on the license page.
I'll provide fixes for the first two in the coming days, but this should unblock anyone who is wanting to see something here, even if it's not quite complete. :-)
----
The patch makes the following changes:
- The license registry is now asynchronous, since the data comes from disk.
- I moved the default license collector from the foundation package to the services package since it uses the default asset bundle now.
- The FLX builder now includes the LICENSE files of each Dart package mentioned in the `.packages` file.
Removed old Stack layout and added a simple-to-extend interface for the
new drawer header. Also added a specialized UserAccountsDrawerHeader
consistent with Material Design guidelines.
In order to have an efficient way to display clipped avatars,
backgroundImage was added inside of the container's BoxDecoration.
Fixes#4964. This commit also fixes#4567 where the radius property
actually sets the diamater.
We were stacking up two dismiss timers. Now we don't start a new timer
if we've already got one. Also, fix an animation leak caught by the
test.
Fixes#4640
Rather than requiring the developer to specify a full Decoration, we now
just take an ImageProvider for the thumb image. Also, fix
ImageFit.scaleDown to actually work.
Fixes#4571Fixes#4673
* Make the size setter on RenderBox protected to avoid setting from
outside the class.
* Make normalize on BoxConstraints always return an object that
isNormalized.
Now that protected can be accessed from inside the same library, we can
use protected in a number of new places and we can remove some
trampolines we were using to work around its previous semantics.
navigating away.
Details are in the bug, but when we navigate away, the overscroll
indicator around the Scrollable would change the widget hierarchy. This
would trigger the Scrollable to rebuild, which would cause its
scrollOffset to be clamped to 0 for a frame.
BUG=https://github.com/flutter/flutter/issues/4597
The new `empty_statements` lint (in the next DEV roll), flags these empty statements. Harmless, except the one in `basic.dart` that fixes a real-life bug. :)
