Plugin projects are created by running `flutter create --plugin <name>`.

An example app is also created in the plugin project, using the normal 'create' template, which has been modified to allow for conditional plugin code.

Modified the android package name to match package naming conventions (all lower-case, and must match the directory name).

This patch adds a notification to SliverChildDelegate that says which
children are alive after each layout. The delegate can use this
information to optimize it's underlying model of the children (e.g., by
discarding models for children that are far outside the live range).

Fixes #9045

This reverts commit 326355f0.

Also refactors demos list into a class with `synchronized` and
`profiled` properties.

When run with --trace-startup, as we do in this test, the VM stores
trace events in an endless buffer instead of a ring buffer. To avoid
out-of-memory conditions, we restrict timeline collection to a subset.

Fixes #7307

The new scrolling world marks nodes dirty between frames instead of
waiting for the frame, and we've decided that's actually ok.

There's no test here because the test harness has a bug that hides
this exception. I will submit a separate PR to fix the harness, which
will fix a test that, without _this_ patch, fails. All of which is to
say, this is actually already tested.

This reverts commit e2b49d64.
