 A new Flutter project.
 
-## Getting Started
+## 配置签名
+为发布渠道创建JAVA密钥储存(密钥库)文件 `.jks`，或者 `.keystore` 文件。
 
-This project is a starting point for a Flutter application.
+```bash
+keytool -genkey -v -keystore android/app/sky.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload
+```
 
-A few resources to get you started if this is your first Flutter project:
+请记住你输入的主密码和键密码
 
-- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
-- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+因为本项目将会发布2个以上的渠道，所以密钥库也会有2个以上，请注意区分 同一个发布渠道必须使用同一个密钥库，不要生成多个。
 
-For help getting started with Flutter development, view the
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
+为了编译管理方便，我们将密钥库文件放在了项目代码内。
+
+`key.properties` 文件用于存放密钥库的相关信息，但是我们不用这个文件，而是直接在 `build.gradle` 中写入密钥库的相关信息。
+因为我们将密钥库文件本身都已经储存在git中了，也就没必要再单独存放密钥信息了。
+
+## 编译
+```bash
+flutter build apk --split-per-abi --release --flavor dev -t lib/main_dev.dart
+```
+
+## 获取编译包的签名
+用于APP备案，国内商店上架等
+
+需要使用到`apksigner`工具，对于Windows来说，它在：`C:\Users\myUser\AppData\Local\Android\Sdk\build-tools\34.0.0\lib`
+
+在 `git bash` 中我需要使用 `apksigner.bat` 来使用它；在其它系统中应该可以直接使用 `apksigner` 命令即可。
+
+参阅：[How to find signature of apk file?](https://stackoverflow.com/questions/38558623/how-to-find-signature-of-apk-file)
+
+```bash
+apksigner verify --print-certs -v build/app/outputs/flutter-apk/app-sky-release.apk
+```
