using-fastlane-in-flutter-and-ci

在 Flutter 和 CI 中使用 Fastlane

前置条件：

• 了解 Fastlane 是什么，以及它的工作原理

• 项目按照这些文档构建正确

• 在 Google Play Console 中完成 Android 应用设置

• 在 AppStore Connect 中完成 iOS 应用设置

• 已安装 Flutter，并已创建项目

步骤

1. 打开 Flutter 项目

2. 运行：cd ios

3. 运行：fastlane init 并按照提示操作

4. 将 Fastfile 的内容替换为以下内容：

#!/bin/bash

echo "App Release Automator by @rodydavis"

action="$1"
red=`tput setaf 1`
green=`tput setaf 2`
reset=`tput sgr0`

if [ ${action} = "build" ]; then

    echo "${green}Generating built files.. ${reset}"
    flutter packages pub run build_runner clean
    flutter packages pub run build_runner build --delete-conflicting-outputs

    pub global activate pubspec_version
    git commit -a -m "Build $(pubver bump patch)"
    
    echo "${green}Building Project...${reset}"
    find . -name "*-e" -type f -delete
    flutter format .
    flutter clean

    echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"

    echo "${green}Building APK...${reset}"
    flutter build apk

    echo "${green}Builing IPA..${reset}"
    cd ./ios && pod install && pod repo update && cd ..
    flutter build ios

    git commit -a -m "Project Rebuilt"


elif [ ${action} = "beta" ]; then

    echo "${green}Generating built files..${reset}"
    flutter packages pub run build_runner clean
    flutter packages pub run build_runner build --delete-conflicting-outputs

    pub global activate pubspec_version
    git commit -a -m "Beta $(pubver bump patch)"
    
    echo "${green}Building Project...${reset}"
    find . -name "*-e" -type f -delete
    flutter format .
    flutter clean

    echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"

    echo "${green}Building APK...${reset}"
    flutter build apk

    echo "${green}Sending Android to Beta...${reset}"
    cd ./android && fastlane beta && cd ..

    echo "${green}Builing IPA..${reset}"
    flutter build ios

    echo "${green}Sending iOS to Beta..${reset}"
    cd ./ios && fastlane beta && cd ..

    git commit -a -m "Sent to Beta"


elif [ ${action} = "release" ]; then

    echo "${green}Generating built files..${reset}"
    flutter packages pub run build_runner clean
    flutter packages pub run build_runner build --delete-conflicting-outputs

    pub global activate pubspec_version
    git commit -a -m "Production $(pubver bump minor)"

    echo "${green}Building Project...${reset}"
    find . -name "*-e" -type f -delete
    flutter format .
    flutter clean

    echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"

    echo "${green}Building APK...${reset}"
    flutter build apk

    echo "${green}Sending Android to Production...${reset}"
    cd ./android && fastlane release && cd ..

    echo "${green}Builing IPA..${reset}"
    flutter build ios

    echo "${green}Sending iOS to Production...${reset}"
    cd ./ios && fastlane release && cd ..

    git commit -a -m "Sent to Production"

fi

echo "${green}Successfully completed${reset}"

5. 运行：cd .. && cd android

6. 运行：fastlane init 并按照提示操作

7. 将 Fastfile 的内容替换为以下内容：

# Uncomment the line if you want fastlane to automatically update itself
# update_fastlane

default_platform(:android)

platform :android do
  desc "Prepare and archive app"
  lane :prepare  do |options|
    #bundle_install
    Dir.chdir "../.." do
      sh("flutter", "packages", "get")
      sh("flutter", "clean")
      sh("flutter", "build", "appbundle", "--release")
    end
  end
  
  desc "Push a new beta build to Google Play"
  lane :beta do
    prepare(release: false)
    upload_to_play_store(
      track: 'beta',
      aab: "../build/app/outputs/bundle/release/app.aab"
    )
    add_git_tag(
      grouping: "fastlane-builds",
      prefix: "v",
      build_number: android_get_version_code
    )
    push_to_git_remote
  end

  desc "Push a new release build to the Google Play"
  lane :release do
    prepare(release: true)
    upload_to_play_store(
      track: 'production',
      aab: "../build/app/outputs/bundle/release/app.aab"
    )
    add_git_tag(
      grouping: "release",
      prefix: "v",
      build_number: android_get_version_name
    )
    push_to_git_remote
  end
end

8. 运行：fastlane add_plugin versioning_android，如有需要，请输入密码

9. 运行：cd ..

现在，你可以发布应用的 Beta 版本了！

iOS：运行 cd ios && fastlane beta

Android：运行 cd android && fastlane beta

敬请期待后续文章，我们将介绍如何使用这些 Fastlane 子目录，通过 GitHub Actions CI 自动化发布流程。
