1. 創(chuàng)建packages
flutter create --template=package flutter_easy_use_tools
2. 實現(xiàn)功能
lib下創(chuàng)建src文件夾，src文件下的文件是不對外開放的，開放則通過flutter_easy_use_tools.dart來對外開放树埠。
library flutter_easy_use_tools;
export 'src/extension/string_extension.dart';
export 'src/utils/num_util.dart';
export 'src/utils/string_util.dart';
export 'src/widgets/custom_inner_shadow.dart';
3. 檢查pubspec.yaml
name: flutter_easy_use_tools
description: A new Flutter project.
version: 0.0.1
homepage: https://github.com/yuanzhiying/flutter_easy_use_tools
4. 驗證packages
$ flutter packages pub publish --dry-run
$ flutter packages pub publish --dry-run
Publishing flutter_easy_use_tools 0.0.1 to https://pub.flutter-io.cn:

5. 發(fā)布packages
執(zhí)行flutter packages pub publish橄唬，點擊其中鏈接瀏覽器打開授權，需要登錄谷歌賬號盐杂。
先用命令測試能否訪問谷歌：$ curl www.google.com
$ flutter packages pub publish

如果使用了代理，則需要在客戶端上執(zhí)行終端代理命令：
我的代理命令如下：
export HTTP_PROXY=http://127.0.0.1:1081; export HTTPS_PROXY=http://127.0.0.1:1081; export ALL_PROXY=socks5://127.0.0.1:1080
執(zhí)行完之后，再執(zhí)行發(fā)布命令廊佩。
6. 查看自己發(fā)布的packages
使用谷歌賬號，登錄網(wǎng)站：https://pub.dev/
查看自己發(fā)布的插件：
搜索自己發(fā)布的插件：
7. 更新插件
編寫完新的插件代碼后：
① 修改pubspec.yaml文件中的version: 0.0.1為version: 0.0.2靖榕。
② CHANGELOG.md增加更新日志标锄，最新版本在最上面。
③ 修改README.md文件茁计。
④ 提交git代碼料皇，添加tag。
$ flutter packages pub publish 重新發(fā)布。
8. 為插件添加example
在packages目錄下践剂，創(chuàng)建example項目鬼譬。
添加插件到example，
dependencies:
flutter:
sdk: flutter
flutter_easy_use_tools:
path: ../
example中使用：
import 'package:flutter_easy_use_tools/flutter_easy_use_tools.dart';
在packages頁面查看：
9. 插件問題完善
在我的插件后臺可以看到插件不完善和不規(guī)范的地方舷手，可以完善以提高評分拧簸。
代碼格式化執(zhí)行命令：
flutter format .
$ flutter format .
Formatting directory .:
Unchanged example/lib/main.dart
Unchanged example/test/widget_test.dart
Unchanged lib/flutter_easy_use_tools.dart
Formatted lib/src/extension/string_extension.dart
Formatted lib/src/utils/num_util.dart
Formatted lib/src/utils/string_util.dart
Formatted lib/src/widgets/custom_inner_shadow.dart
Unchanged test/flutter_easy_use_tools_test.dart
10. 避免通過package:flutter_easy_use_tools/src/...方式來使用插件。
應該通過插件提供的對外文件來使用：
import 'package:flutter_easy_use_tools/flutter_easy_use_tools.dart';
11. 為packages創(chuàng)建文檔
使用 dart doc 可以為 Library 生成 API 文檔男窟。
dartdoc 解析源文件去查找使用 /// 語法標注的文檔注釋盆赤。
進入packages根目錄，執(zhí)行dart doc .命令歉眷。
$ dart doc .

dartdoc failed: Top level package requires Flutter but FLUTTER_ROOT environment variable not set.
執(zhí)行失敗牺六。
查看FLUTTER_ROOT，

$ source ~/..bash_profile
