Adhere to Effective Dart Guide directives sorting conventions.

This rule has a
quick fix
available.
Details
DO
follow the directive ordering conventions in
Effective Dart
:
DO
place
dart:
imports before other imports.
import 'package:bar/bar.dart';
import 'package:foo/foo.dart';
import 'dart:async'; // LINT
import 'dart:html'; // LINT
import 'dart:html'; // OK
import 'package:bar/bar.dart';
import 'dart:async'; // LINT
import 'package:foo/foo.dart';
GOOD:
import 'dart:async'; // OK
import 'dart:html'; // OK
import 'package:bar/bar.dart';
import 'package:foo/foo.dart';
DO place package: imports before relative imports.
import 'a.dart';
import 'b.dart';
import 'package:bar/bar.dart'; // LINT
import 'package:foo/foo.dart'; // LINT
import 'package:bar/bar.dart'; // OK
import 'a.dart';
import 'package:foo/foo.dart'; // LINT
import 'b.dart';
GOOD:
import 'package:bar/bar.dart'; // OK
import 'package:foo/foo.dart'; // OK
import 'a.dart';
import 'b.dart';
DO specify exports in a separate section after all imports.
import 'src/error.dart';
export 'src/error.dart'; // LINT
import 'src/string_source.dart';
GOOD:
import 'src/error.dart';
import 'src/string_source.dart';
export 'src/error.dart'; // OK
DO sort sections alphabetically.
import 'package:foo/bar.dart'; // OK
import 'package:bar/bar.dart'; // LINT
import 'a/b.dart'; // OK
import 'a.dart'; // LINT
GOOD:
import 'package:bar/bar.dart'; // OK
import 'package:foo/bar.dart'; // OK
import 'a.dart'; // OK
import 'a/b.dart'; // OK
