Don't show handles outside the text field's boundary.

* Always composite PhysicalModels
* Update tests to check layer tree instead of canvas for Physical shadows

* No image shader caching in default shader warm-up

It turns out that no matter how small the image is, too much memory will
be used. Hence remove the image shader caching and let the client
implement itself based on needs.

Fixes https://github.com/flutter/flutter/issues/29172

* Fix

* Install JDK and Android SDK only for integration and build tests

* Updated ListView Sample code with more examples for different constructors and also to match asset diagrams.

* Fixed MIA semicolons.

* Code cleanup.

* Added context for ListView.builder example.

* Analyzer does not like const and static usages.

* Replaced the const declarations with final. The analyzer does not like the use of const here, at all.

* Fixed parameterized declarations.

* Add a `flutter create --list-samples` command

* Add some comments/docs

* Tweak text
