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. |

Welcome to the Flutter API reference documentation.
Flutter is Google’s mobile UI framework for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The API reference herein covers all libraries that are exported by the Flutter SDK.

Importing a Library
Framework Libraries
Libraries in the "Libraries" section below (or in the left navigation) are part
of the core Flutter framework and are imported using
'package:flutter/<library>.dart', like so:
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
Dart Libraries
Libraries in the "Dart" section exist in the 'dart:' namespace and are imported
using 'dart:<library>', like so:
import 'dart:async';
import 'dart:ui';
Except for 'dart:core', you must import a Dart library before you can use it.
Other Libraries
Libraries in other sections are supporting libraries that ship with Flutter.
They are organized by package and are imported using
'package:<package>/<library>.dart', like so:
import 'package:flutter_test/flutter_test.dart';
import 'package:file/local.dart';
Finding Other Libraries
Flutter has a rich community of packages that have been contributed by the open-source community. You can browse those packages at pub.dev/flutter
