This PR modifies the existing API docs samples to use DartPad so that all of the samples are now interactive apps on the API docs site. It also removes the restriction for the max width of the description area so that the dartpad region can expand horizontally. I updated the first paragraph on the API docs to indicate that Flutter is more than just mobile now (same text as the README.md at the top level). I modified a few of the examples so that they looked nicer, and fit better on the page. I added the sample description text above each DartPad instance, since that often defines the context of the example. I removed animations and images when they were redundant with the sample content. There were a few that made sense to keep, so I did.
This directory contains tools and resources that the Flutter team uses during development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course they may be interesting if you are curious.
The tests in this directory are run in the framework_tests_misc-*
shards.
