Travis CI 构建
Building Flutter APKs and IPAs on Travis 这篇文章详细介绍了如何在 Travis CI 上为 Flutter 项目打包 Android/iOS 应用，不过实际构建时存在几个问题，原文中的 .travis.yml 配置如下：

Android
wget - 403 Forbidden
这个错误发生在执行 wget http://services.gradle.org/distributions/gradle-3.5-bin.zip 的时候，把 gradle 的下载路径替换成 https 即可。
Remote branch alpha not found in upstream origin
这个错误发生在下载 Flutter 代码的阶段，原文中的配置会下载 Flutter 的 alpha 分支代码，但是目前 Flutter 的仓库已经没有 alpha 分支，切换到 stable 分支即可，即：git clone https://github.com/flutter/flutter.git -b stable --depth 1。
Failed to install the following Android SDK packages as some licences have not been accepted
详细错误信息如下：

| [ ] > Failed to install the following Android SDK packages as some
licences have not been accepted.
[ ] build-tools;28.0.3 Android SDK Build-Tools 28.0.3
[ ] platforms;android-29 Android SDK Platform 29
[ ] To build this project, accept the SDK license agreements and
install the missing components using the Android Studio SDK Manager.
|
这个错误是由于没有同意 Android SDK 的许可证协议，在 before_script 中加入如下配置即可：
1
2
| yes | sdkmanager "platforms;android-29"
yes | sdkmanager "build-tools;28.0.3"
|
iOS
pip: command not found
这个错误在执行 pip install six 时遇到，经过实际验证构建 iOS 应用时并不需要此行配置，所以删掉即可。
Xcode 11.0 or greater is required to develop for iOS
原文中的配置使用的是 Xcode 8.3，最后打包时会提示此错误，将 osx_image 设置为 xcode11 即可。

Codemagic
最后推荐 Codemagic 这个服务，提供云端打包 Flutter 应用的功能，省去了 Travis CI 配置的步骤，免费用户每月有500分钟的额度来执行构建。
