如何使用 fastlane 缩短 Flutter iOS 应用程序的构建时间

Question

我的问题是，当使用 Firebase（特别是 cloud_firestore）时，Flutter iOS 应用程序的构建时间变得很长，以至于我在 Bitrise 上的 CI 构建超时（28 flutter build --release 的分钟，而 fastlane 的 build_ios_app 又超过 20 分钟）。所以我无法在我的 CI 上执行完整的 iOS 构建。缓存当然是可能的，但首先必须完成初始构建：/

根据this guide it's necessary to rebuild iOS app when archiving with Xcode using Fastlane. There is, however, a discussion on official Github repo介绍了直接从 Flutter 发布 IPA 文件的命令，但目前还不可能。

我的问题是 - 有什么方法可以缩短构建时间，例如通过跳过 fastlane 步骤中的构建，只是辞职并将 .app 文件归档到 .ipa？我一个人搞不定。

Here you may find a sample Flutter app 启用 cloud_firestore。

您可以在下面找到我的 Bitrise 和 fastlane 配置：

            set -x

            cd $BITRISE_FLUTTER_PROJECT_LOCATION/ios
            pod repo update
        title: Update pods repository
test:
    before_run:
    - prepare
    steps:
    - flutter-build@0.9.2:
        inputs:

        - ios_additional_params: "--release --no-codesign -t lib/main.dart

        is_always_run: true
    - fastlane@2.4.0:
        title: fastlane iOS
        inputs:
        - work_dir: "$BITRISE_FLUTTER_PROJECT_LOCATION/ios"
        - lane: ios test
    after_run:
    - finish
    envs:
    - opts:
        is_expand: false
    FLAVOR: tst
    - opts:

    steps:
    - cache-push@2.1.1:

        - ignore_check_on_paths: "~/Library/Developer/Xcode/DerivedData"
        - cache_paths: |-
            $BITRISE_FLUTTER_PROJECT_LOCATION/build
            $BITRISE_FLUTTER_PROJECT_LOCATION/ios/Pods
            ~/Library/Developer/Xcode/DerivedData
app:
envs:

- opts:
    is_expand: false
    BITRISE_SCHEME: tst
- opts:
    is_expand: false
    BITRISE_EXPORT_METHOD: ad-hoc

这里是快车道：

default_platform(:ios)

platform :ios do
  lane :test do
    match(
      type: "adhoc",
      force_for_new_devices: true,
    )
    automatic_code_signing(
      use_automatic_signing: false
    )
    update_project_provisioning(
      profile: ENV["sigh_pl.flutter.buildTimeIssue_adhoc_profile-path"],
      build_configuration: "Release",
      code_signing_identity: "iPhone Distribution"
    )
    build_app(
      scheme: "tst",
      configuration: "Release",
      xcargs: "-allowProvisioningUpdates",
      export_options: {
        signingStyle: "manual",
        method: "ad-hoc",
        provisioningProfiles: {
          "pl.flutter.buildTimeIssue": "match AdHoc pl.flutter.buildTimeIssue"
        }
      },
      output_name: "Runner.ipa"
    )
    appcenter_upload(
      app_name: "Name",
      owner_name: "Owner",
      group: "All-users-of-Name",
      ipa: "Runner.ipa"
    )
  end
end

Answer 1

我用 https://github.com/invertase/firestore-ios-sdk-frameworks 的 Cloud Firestore 框架的预编译二进制文件修复了同样的问题，如下所示：

# ...
target 'Runner' do
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '6.26.0'

# ...
end
