flutter/examples/layers/README.md
Ian Hickson a52c7b470d Update the examples/ README and associated fixes. (#9090) 
This yak shave went as follows:

Fix https://github.com/flutter/flutter/issues/8795 by adding stocks to
the examples README.

Notice the layers entry in that README isn't quite right either.
Update that.

Check the layers/README file is worth pointing at.

Update the layers/README.

Let's run some of the layer tests to see if they still work.

Oops, need to update them to gradle.

Ok let's try running them again.

Oops, sector is broken.

Add a test for sector.

Fix sector. Find you need to add an assert to a const constructor.

Notice we need to turn const asserts on for the analyzer.

Notice the analysis_options files are out of sync with each other and
with the full list of lints.

Turn on the lints that should be on.

Fix the bugs that finds.

Examples of Flutter's layered architecture

This directory contains a number of self-contained examples that illustrate Flutter's layered architecture.

  • raw/ These examples show how to program against the lowest layer of the system. They manually receive input packets and construct composited scenes.

  • rendering/ These examples use Flutter's render tree to structure your app using a retained tree of visual objects. These objects coordinate to determine their size and position on screen and to handle events.

  • widgets/ These examples use Flutter's widgets to build more elaborate apps using a reactive framework.

  • services/ These examples use services available in Flutter to interact with the host platform.

To run each example, specify the demo file on the flutter run command line, for example:

flutter run raw/spinning_square.dart
flutter run rendering/spinning_square.dart
flutter run widgets/spinning_square.dart
