-# flutter-common-widgets-app
-
-### 使用背景
-* 鉴于目前flutter官方庞大的小部件（widget）系统以及api文档，只有文字描述，而没有可视化实例。
-* 我们开发这套app,可以系统的看到常用小部件（widget）的用法。
-* 辅助初学者更快上手,flutter官方小部件（widget）
-
-
-
-### 参考资料
-
-* [flutter-widgets的官方库地址]( https://docs.flutter.kim/widgets/widgets-library.html )
-* [flutter-widgets的官方目录集]( http://doc.flutter-dev.cn/widgets/ )
-* [sqlitestudio 本地可视化工具] (https://sqlitestudio.pl/index.rvt)
-
-### 分支命名及使用规范
-
-* 分支命名规范
-	- 自己开发分支命名统一为 username ，如：yifeng
-	- 分支两条主线为 Master分支和develop分支
-	- Master作为发布分支，develop作为开发测试分支、自己开发分支从dev checkout出去，发布即 merge to master
-
-* 分支合并规范
-	- 从最新的develop分支checkout出自己的开发分支
-	- 在自己开发开发分支开发完成后，先去develop分支pull最新代码，
-	- 将develop 分支最新代码 merge 到自己分支，确保无冲突
-	- 再切回develop分支merge自己开发分支代码，确保无冲突，且能正常运行
-
-### commit 提交规范
-* $git cz
-
-* 用于说明 commit 的类别，只允许使用下面7个标识。
-
-  - feat：新功能（feature）
-
-  - fix：修补bug
-
-  - docs：文档（documentation）
-
-  - style： 格式（不影响代码运行的变动）
-
-  - refactor：重构（即不是新增功能，也不是修改bug的代码变动）
-
-  - test：增加测试
-
-  - chore：构建过程或辅助工具的变动
-
-
-### 代码规范
-* 文件命名规范
-	- 文件命名使用下划线命名法，如：hello_world
-	- 请使用英文进行命名，不允许使用拼音。命名要求具有可读性，尽量避免使用缩写与数字
-	- 未完待续
-
-* 代码编码规范
-	- 文件编码统一使用 UTF-8 编码；
-	- 前端编码采用首字母小写驼峰法. Widget Class 必须采用首字母大写驼峰法.
-
-### 文件目录结构(以LIb文件说明)
-
-- lib
-	- main.dart 入口文件
-	- common 公共的method
-	- components widget
-	- generated
-	- model 存放模型, 不应该加入逻辑层
-	- router 路由
-	- views 展示界面
-	- widget (与components概念重合,废弃)
